NOTES ON THE REPAIR TECHNIQUE USED IN THE MAIN GROUP 41

Two different repair techniques are used in body repair.

These are welding and bonding/riveting.

If the repair instructions do not specify a repair technique, then welding must always be used.

The bonding/riveting repair technique is always described in detail in the repair instructions.

Quality standards must be met.

Blind rivet

1.0 Recommended tools and equipment

  • Blind riveting tongs
  • Rivet head extension

Setting blind rivets:

  • Refer to repair instructions for rivet size.
  • Position bore holes for blind rivets in accordance with specification in repair instructions. If necessary, carry over the positions of the blind rivets to the new part.
  • Drill holes that exceed the outer diameter of the blind rivet (example Ø 4.2 mm with 4 mm blind rivet and Ø 6.8 mm with 6.5 mm blind rivet).
  • The edge of the hole must even on both sides. If necessary, sand down and even out surfaces (e.g. edges of punch rivet connections). Deburr bore holes.
  • APPLY ADHESIVE.
  • Insert blind rivet. If necessary, remove adhesive that has emerged.

    Position blind rivet tool vertically. Use rivet head extension if accessibility is poor.

  • Rivet blind rivet with blind rivet tool. In the meantime clean rivet head if dirty with adhesive. Risk of damage to rivet head by penetrating adhesive.
  • Seal blind rivet with SEALANT D1 (risk of corrosion).
  • Seal cavities after work on vehicle paintwork on with CAVITY PRESERVATION (risk of corrosion).

Bonding on painted/primed surfaces

IMPORTANT: These repair instructions apply only to components of the outer skin and not to structural components.

These include roof outer skin, tail panel, rear side panels and components of the luggage compartment floor.

Follow the vehicle-specific repair instructions.

Only the repair method described there must be used! Conform with safety regulations .

Overview of topics:

  1. Equipment
  2. Expiry date of consumables
  3. Preparation of surface

  5. Hardening times
  6. Subsequent treatment
  7. Disposal of adhesive

1.0 Equipment

  • CLEANING AGENT R1
  • ADHESIVE K5
  • CARTRIDGE GUN

2.0 Expiry date of consumables:

  • Glue cartridge is marked with a date.
  • Do not use adhesive after this date.

3.0 Preparation of surface:

3.1 Preparation of the surface on the vehicle (series status):

  • Establish a level bonding surface (e.g. grinding).
  • Do not sand primed bonding surfaces.

    If the bonding surface is painted in the vehicle colour, the paint must be completely sanded off.

  • If necessary, pre-clean bonding surfaces with cavity sealing wax remover.

    Clean bonding surfaces with cleaning agent R1.

  • Allow cleaned surfaces to dry for approx. 5 min.

    Bonding surfaces must be completely dry.

3.2 Preparation of the surface on the vehicle (replacement of a bonded component):

  • Remove adhesive residue completely from vehicle. Remove all old reinforcement plates if necessary (e. g. rear side panel).
  • Do not prime in the area of the bonding surfaces! Adhesive insufficiently bonds to primer.

    If priming is needed after straightening work, cover the bonding surfaces.

  • If necessary, pre-clean bonding surfaces with cavity sealing wax remover.

    Clean bonding surfaces with cleaning agent R1.

  • Allow cleaned surfaces to dry for approx. 5 min.

    Bonding surfaces must be completely dry.

3.3 Preparation of surface on new part:

  • Do not remove primer on new part.

    Do not grind/sand bonding surfaces.

  • Clean bonding surfaces with cleaning agent R1.
  • Allow cleaned surfaces to dry for approx. 5 min.
    Bonding surfaces must be completely dry.

4.0 Adhesive application:

  • Processing temperature of glue cartridge 18 ºC 30 ºC.
  • Object temperature, vehicle and new parts, at least 15ºC.
  • Do not use an air-powered cartridge gun.
  • Insert glue cartridge into cartridge gun, remove cap and allow both adhesive components to emerge. Strip adhesive components uniformly and attach mixing tube.
  • Allow approx. 10 cm of mixed adhesive to emerge and then apply the mixed adhesive first on one side of the bonding surface.
  • After applying the adhesive, check whether an adhesive component has emerged at the back of the glue cartridge. If yes, break off the bonding procedure. Clean new part. Use new glue cartridge.
  • Pot life of mixed adhesive approx. 2 h. A change of mixer is necessary only if no material has flowed through the mixer for a period of 30 min.
  • Join components and secure in position.
  • Remove excess adhesive.

5.0 Hardening times:

  • Do not move the vehicle before the adhesive has hardened.

    Check the degree of hardness of the adhesive with a fingernail.

    If the adhesive cannot be pressed in any further with a fingernail, the vehicle may be moved (without engine force) for further processing applications (e.g. painting).

  • Vehicle strength for driving applications is achieved after: 48 h at an object temperature of at least 15 ºC (corresponds to approx. 18 ºC room temperature).

    Or 1 h in the spray booth (spray booth temperature 80 ºC/object temperature 60 ºC).

  • When using radiant heaters, make sure that the object temperature does not exceed 85 ºC.

    Excessively high temperatures will destroy the adhesive.

  • Remove contamination caused by adhesive residue immediately.

    Hardened adhesive can only be removed mechanically.

6.0 Subsequent treatment:

  • Reseal areas which are cavity-sealed as standard.

7.0 Disposal of adhesive:

  • Hardened adhesive is disposed of as normal waste.
  • Empty glue cartridges are disposed of as normal waste.
  • Non-hardened adhesives and mixtures of adhesive and solvent and the like must be disposed of as hazardous waste.

These regulations apply to the Federal Republic of Germany.

For other countries, comply with the (possibly differing) nationally applicable regulations.

Corrosion protection

NOTE: Following repairs, the corrosion protection work already begins with the correct removal of the underbody protection, anti-drumming layer and seam sealing in the repair area.

The PRODUCTS RECOMMENDED by BMW are optimized with regard to corrosion protection.

1.0 Removing and applying sealant:

1.1 Removing sealant:

IMPORTANT:

  • Do not burn off PVC material (sealant) with an autogenous torch or similar or heat to temperatures above 180 ºC. This would generate highly corrosive hydrochloric acid and release harmful vapor.
  • The new sealant does not adhere appropriately to burnt polyvinyl chloride material and hence subsequent rust creep is possible.

Remove PVC material with a rotating steel brush, or heat PVC to maximum 180 ºC with a hot air blower and scrape off with a spatula.

Remove PVC material with a rotating steel brush, or heat PVC to maximum 180 ºC with a hot air blower and scrape off with a spatula.

1.2 Applying sealant:

Prime and seal all weld seams that are sealed with sealant in original condition immediately after repair work. Replace damaged or removed anti-drumming layers.

NOTE: Required spray gun for sealant (order number 81 49 0 300 887).

Seal blind rivet with SEALANT (risk of corrosion).

2.0 Basics of cavity preservation:

Apply cavity preservation after all body repairs.

Concluding cavity preservation is the most important part of all corrosion protection measures.

Use the cavity protection spray only for smaller-scale straightening work where the parts in question are easily accessible. Use the PRESSURE CUP GUN for all other repairs. Cavity protection agent is available in different container sizes.

Use the relevant sensors with tubes for the different cavity areas.

IMPORTANT: Incorrectly performed cavity protection can, especially in the case of steel/aluminum joints, give rise to a non-calculable product liability and safety risk.

The best repair is worth nothing if the subsequent cavity protection measures are not conscientiously carried out.

2.1 Cavity preservation of steel parts:

New doors and lids must be sealed with cavity protection agent after being painted.

New sheet-metal parts or cavities, weld seams and folds formed by new sheet-metal parts must be sealed with cavity protection agent after being painted.

The cavities affected must be sealed with cavity protection agent after all straightening work.

2.2 Cavity preservation of aluminum parts:

New doors, lids and side panels made of aluminum are not sealed with cavity protection agent.

After all straightening work on aluminum components, the cavities affected must be sealed with cavity protection agent after being painted.

After all welding work (E52 only) on aluminum components, the cavities affected must be sealed with cavity protection agent after being painted.

Cavities, seams and folds formed from new sheet metal parts or extruded profile must be sealed with cavity protection agent after being painted.

Emc screws

(EMC = Electro-Magnetic Compatibility)

1. Purpose:

  • EMC SCREWS are used in the Bonding/Riveting repair method to re-establish bonding transition.
  • They assume the function of welded joints, which ensure transition to ground between the individual components.
  • The punch or blind rivets used in the repair do not guarantee permanent bonding transition between the individual components!
  • The EMC screws ensure the operational reliability and safety of the electrical/electronic components following repairs!

2. Procedure, aluminum front end:

  • Each welded joint which is opened must be replaced by at least 2 EMC screws.
  • Position the 2 screws on the flange on which the weld seam has been separated. In the event of partial replacement, position the screws in the area of the component overlap.
  • In the case of repairs using partial replacement, the number of EMC screws described in the repair instructions must be fitted.
  • Drill holes to a diameter of 4.2 mm and insert screws.
  • Seal EMC screws with PU sealing material (risk of corrosion).

3. Procedure, steel body:

  • Install the number of EMC screws described in the repair instructions.
  • Drill holes to a diameter of 4.2 mm and insert screws.
  • Seal EMC screws with PU sealing material (risk of corrosion).

General instructions on paintwork

The marked area serves as reference value for paintwork. This area may differ from the illustration for technical painting reasons.

Touching-up areas are taken into account.

Special procedure for matte paintwork: Matte paintwork cannot be touched up since the painted surface cannot be polished.

General notes for labelling with adhesive films

In the event of a repair the adhesive films must be partially or completely replaced. The basic procedure for all areas of the vehicle is described below.

In addition, vehicle-specific repair instructions are available.

1. Preparation: Wash and dry vehicle. Rework with compressed air as required in area of joints.

Clean complete component surface with glass cleaner (BMW part number 83 12 0 396 775). Also clean the inside of the component in areas, in which adhesive films are applied.

Only carry out repair work with clean hands!

IMPORTANT: Labels can only be applied to recently painted components after a waiting period of 2 weeks . The paint hardening is only fully completed after this time.

2. Procedure for applying labels: All adhesive films in the repair kit are marked with numbers. Prepare the required plastic films prior to start of repairs.

The templates included in the repair kit assist orientation. A straight line running over the different components is the top priority.

Pull off the templates positioning of the adhesive films.

Only throw away templates after completion of all repair work, as some templates are used several times.

Body+and+Frame

Templates are always applied along the light edge (1). The light edge is the reflection of the light source in radius (see arrow).

Roughly align the adhesive film using a template.

For large adhesive films, pull off the first 20 cm of protective film and fold back the edge.

Align and lightly press down the adhesive film. Use only one finger for this and not the entire hand so that air pockets are unable to form under the adhesive film.

Pull off the remaining protective film and press down the adhesive film from front to rear and from inside to outside.

If faults are made in applying the adhesive film, it can be pulled off and repositioned several times. When no further corrections have to be made, use a squeegee to press down the adhesive film firmly from inside to outside.

Lay protruding ends of the adhesive film around the component edge and press down firmly.

Body+and+Frame

Carefully pull off backing film (1) at an acute angle.

Grinding aluminum components

1.0 Recommended tools and equipment

Grinding work on the outer skin:

  • To carry out grinding work by hand or machine, you must use the recommended tools and equipment.

    The workbay can be cleaned with conventional extractor systems (low dust concentration).

Grinding work on the structure (except Z8):

  • To carry out grinding work by hand or machine, you must use the recommended tools and equipment.

    The workbay can be cleaned with conventional extractor systems (low dust concentration).

Z 8 Spaceframe structure:

  • To carry out machine grinding on the structure, you must use the recommended device with grinding dust extractor facility.

    The workbay must be cleaned with the recommended explosion-proof extractor system.

    High dust concentration, explosion hazard!

2.0 Grinding outer skin and structure

Do not use any abrasives (grinding wheels, paper, etc.) which contain iron (risk of corrosion).

Always replace abrasives which have already been used to treat steel (risk of corrosion).

Use stainless steel wire brushes only (risk of corrosion).

Reduce speed of grinding machines. Excessive speeds cause a smearing effect.

Do not use coarse abrasive grains (only ≥ 80).

Do not grind notches into the material (risk of cracking).

Do not grind the material thin.

Grinding steel parts

1.0 Recommended tools and equipment

  • Tools are recommended for manual grinding work.
  • Machines/equipment are recommended for machine grinding work.

2.0 Grinding outer shell and structure

Always replace abrasives which have already been used to treat aluminum (risk of corrosion).

Do not grind the material thin.

Handling airbags and restraint systems

1.0 Airbags and restraint systems

  • In the case of vehicles with airbags and restraint systems observe the relevant SAFETY INSTRUCTIONS .
  • When straightening work is carried out on the body there is a risk of airbags being accidentally activated when the battery is connected.

    Because of this risk the battery ground cable must be DISCONNECTED prior to all repair work on the body.

HANDLING COMPONENTS AFTER FLOOD DAMAGE

Flood damage can occur if the permissible fording depth of a vehicle is exceeded. Ingress of water can cause damage to the engine (water shock) or components.

Because dirt particles generally enter into the component with the water (e.g. starter motor, wiring harness), the components need to be thoroughly inspected.

Residual moisture in the components leads to corrosion (increased contact resistance in the component), which can lead to a component failure at a later time.

If water ingress into the electrical components cannot be ruled out, it is recommended to replace the component to ensure correct functioning through the vehicle lifetime.

Handling electrical system and electronics

1.0 Battery

  • Explosion hazard in the vicinity of the battery during welding and grinding work. The battery must be REMOVED .

2.0 Control units

  • Control units with visible mechanical damages and/or electrical damages caused by accidents must be replaced.
  • The following risks exist when the battery is connected:
    • Damage to control units resulting from welding work on the body or a line short circuit.
    • Accidental activation of airbags during straightening work on the body.

Because of these risks the ground cable must be DISCONNECTED prior to all repair work.

  • Control units are designed for a temperature of 65 ºC. The temperatures in a spray booth do not pose any problems. If a vehicle is in the spray booth at a displayed temperature of 80ºC, the actual temperature of the vehicle is ≤ 60 ºC (object temperature).
  • Protect control units against the influence of heat >65 ºC (e.g. during welding and drying work with infrared beams or hot air blowers).

3.0 Electrical wires and wiring harnesses

  • Protect electrical wires and wiring harnesses against damage (e.g. during straightening and grinding work).
  • Protect electrical wiring and wiring harnesses against the influence of heat >65 º C (e.g. during welding and drying work with infrared beams or hot air blowers).
  • Do not kink electrical wiring.

4.0 Optical fibres

  • Follow instructions for handling OPTICAL FIBRES .

Information on hazards

1. Aluminum

Hazards/effects Measures/regulations
Repair stage 1 and 2: No hazards/effects none
Repair stage 3: (Welding - only E52)
  • Explosion hazard due to high concentration of fine aluminum dust.

    Arising e.g. during straight-through grinding of coated components in the base material and large-surface grinding of bright-finish components.

  • Explosion hazard due to swirling up of fine aluminum dust in cavities.

    Created by the necessary, thorough cleaning of machining surfaces and tools before and after machining aluminum.

  • Avoid high concentration of fine aluminum dust by means of continuous extraction.
  • Use explosion-proof exhaust extraction unit
  • Do not use compressed air when cleaning the workbay.
  • Avoid swirling up dust when cleaning the workbay.
  • Spontaneous combustion of fine aluminum dust when ignition and fire sources are drawn in.

    E.g.: hot swarf, grinding sparks, cigarettes, etc.

  • Do not operate ignition and fire sources in the intake area of exhaust extraction unit.

2. Carbon

Hazards/effects Measures/regulations
Repair stage 1: No hazards/effects none
Repair stage 2 and 3:
  • Explosion hazard due to high concentration of carbon dust.

    Produced when grinding carbon.

  • Explosion hazard due to swirling up of carbon dust in cavities.

    Created by the necessary, thorough cleaning of machining surfaces and tools before and after machining carbon.

  • Avoid high concentration of carbon dust by drawing it off continuously.
  • Use explosion-proof exhaust extraction unit
  • Do not use compressed air when cleaning the workbay.
  • Avoid swirling up dust when cleaning the workbay.
  • Spontaneous combustion of carbon dust when ignition and fire sources are drawn in.

    E.g.: hot swarf, grinding sparks, cigarettes, etc.

  • Do not operate ignition and fire sources in the intake area of exhaust extraction unit.

Information on metal filler

IMPORTANT: Note the following information before starting to apply metal filler!

  • Country-specific safety and industrial safety regulations
  • Material safety data sheet of manufacturer
  • Processing instructions on the packaging

Storage: Dry at 15ºC to 25 ºC.

Shelf life: The packaging is marked with a date.

Do not use the metal filler after this date.

Surface pre-treatment: Grind surface to a metallic bright-finish. The surface must be clean, dry and free from grease.

Clean the surface with a cleaning agent R1 and let it vent for 2-3 minutes.

Processing: The working temperature of the metal filler must be at least 18ºC.

Body+and+Frame

  1. Metal filler
  2. Hardener

NOTE: The mixture ratio refers to the volume.

Mix metal filler in mixture ratio of 5:2. Mix components thoroughly and free of pores.

IMPORTANT: Do not stir components. Danger of air pockets in metal filler!

Working life of the metal filler is approx. 45 minutes.

Applying filler: Apply pressure to apply a thin layer of metal filler. Carefully coat all edges in gaps with filler.

Then fill gap completely with filler. Apply filler with about 30% excess because the filler will significantly shrink during hardening. A second application of metal filler is not possible due to poor adhesion.

IMPORTANT: Use a narrow spatula to fill the gaps. Apply the filler in one draw if possible. Danger of formation of pores in gaps!

No restrictions related to the layer thickness.

Hardening time: The metal filler must be hardened using a short-wave infrared heater.

  • 10 minutes at 50 ºC - pre-hardening (avoid formation of bubbles/blisters and pores)
  • 10 minutes at 75 ºC - 1st stage hardening
  • 10 minutes at 85 ºC - 2nd stage hardening (avoid material shrinkage)

IMPORTANT: In the first 10 minutes, the temperature of 50ºC may not be exceeded. In contrast, a temperature that is too low may be equalized by extending the time.

NOTE: When the heater is used for the first time, the distances that match the temperature must be determined. Switch the heater on and change the distance until the surface temperature of the metal filler no longer changes for a period of 2 minutes. Measure the temperature with a temperature gauge. When optical temperature gauges are used (Epsilon value 0.92-0.95), the heater must be switched off briefly during the measurement. Record the measurement

Post-processing

WARNING: When grinding, wear a fine dust mask with particulate filter P2-P3!

After cooling, the metal filler can be machined.

Pores and faulty spots that become visible after grinding the surface must be closed with polyester filler (BMW Colour system).

Special procedure for pores: Use a Ø4.2mm drill. Turn the drill by hand to expand the pores in v shape. by t Fill cavities with polyester filler.

Paintwork: Perform paintwork according to the specifications in the painting handbook.

IMPORTANT: When using temperature-controlled infrared radiators, damage to adhesive bonds, paint and vehicle components can occur when drying spatula and filler.

The temperature sensors in the infrared radiator only operate reliably on large, even surfaces.

On small surfaces such as C-pillars or sills, often only a colder, adjacent area is measured.

This leads to actual surface temperatures of up to 130ºC, even if only 70ºC is set on the infrared radiator.

When the rear side walls are partially replaced by bonding and riveting, these high temperatures can lead to a visible pattern in the area of the joint.

Remedy: Check the surface temperatures on small component surfaces during the drying process with an external temperature sensor.

The general rule is: The surface temperatures must not exceed 85ºC.

Metal filler disposal: Hardened metal filler is disposed of as normal waste.

Empty packaging is disposed of as normal waste.

Non-hardened metal filler and mixtures of metal filler with solvent and the like must be disposed of as hazardous waste.

These regulations apply to the Federal Republic of Germany.

For other countries, comply with the (possibly differing) nationally applicable regulations.

Installing a cavity sealing with 2-component pu cavity foam

SOURCING REFERENCE for cavity foam HS1.

IMPORTANT: The cavity foam may only be use for cavity sealing at the points at which cavity sealing is present as standard!

The following repair represents the replacement of a shaped part for the cavity sealing by the use of cavity foam.

This type of cavity sealing is used at points at which shaped parts cannot be used for repairs.

This is the case when large amounts of heat occur (e.g. due to welding, soldering or tin-plating) in the direct vicinity or at the point of the standard cavity sealing.

It is not possible here to install shaped parts for the cavity sealing because of the fire risk! To replace shaped parts with cavity foam at further locations, adopt the procedure shown here and adapt it to the relevant ratios.

It must be ensured that the cavity sealing is fully completed.

NOTE: Check the accessibility for the spraying pipe of the cavity foam to the affected cavity after removing the defective parts.

Properties of cavity foam HS1:

  • 2-component PU foam, solvent-free.
  • Excellent flow capacity, enabling complete sealing of cavities.
  • Good strength, preventing slipping in cavities.
  • Low water absorption, preventing corrosion.
  • Ideal for use as insulating and sealing compound.

Information on dangers/hazards:

  • Avoid eye and skin contact.

    Wear eye protection, solvent-resistant protective gloves and protective clothing.

  • Do not inhale.

    Apply in well ventilated rooms only.

WARNING: Application time after mixing process: within 8 minutes!

  • Completely empty open can after use.
  • Residual amounts which are not used can cause the can to explode on account of a chemical reaction (buildup of heat)!
  • Alternatively, cool the can containing the non-removed residual amount for several hours in cold water.
  • Do not eat, drink or smoke while working with these products.
  • Keep heat and ignition sources far away.
  • Read the manufacturer's information on hazards/dangers (printed on the can) prior to application.

Processing instructions:

  • Observe the expiry date on the cartridge.

    Do not use spray can after the expiry date has passed. After the Use by date the properties of the cavity foam will no longer meet the requirements of the BMW Group.

  • Cavity preservation of the repair area possible after an air drying time of 1 hour.
  • Surface must be clean, free of dust, grease, oil and separating agents .
  • Application temperature at least 15 ºC. Optimally 20 ºC.

IMPORTANT: Foam expands many times over as it sets (change in volume).

  • Before applying to the vehicle, fill a clearly visible cavity of corresponding size with foam on a used part.

    This enables an optimal dosage (i.e. spraying time) to be specified for filling the cavity on the vehicle with foam.

  • Tape off open passages to visible areas with adhesive tape to prevent foam from escaping.
  • The setting takes approx. 30 minutes. Mechanical processing (e.g. drilling, cutting, etc.) is then possible
  • Cavity preservation of the repair area possible after an air drying time of 1 hour.
  • Remove fresh, non-hardened polyurethane foam with adhesive remover 208.

    Sourcing reference: BMW Parts Department.

    Hardened polyurethane foam can only be removed mechanically.

  • Excess hardened polyurethane foam can be disposed of as residual waste.

    Cans that are not entirely empty or are unused and have an expired expiry date are classed as hazardous waste.

    Observe country-specific waste disposal regulations.

  • Observe the manufacturer's processing instructions (printed on the can).

Materials science

1. Aluminum

1.1 Chassis/suspension components READ and observe the Notes on chassis/suspension components before handling aluminum.

1.2 Material influences

Causes Effects/remedies
A galvanic element is created under the effects of moisture by contact with materials such as copper, tin, nickel, iron and zinc.

Tools also used for work on steel components can implant steel particles in the softer surface of an aluminum component.

Surfaces are attacked when fluxing agents are used.

Aluminum/steel grinding dust from adjoining working areas.

This plating process causes aluminum to be removed from the connection point.

This results in surface corrosion or pitting.

New parts and accessory parts which have been approved by the BMW Group for aluminum (screws, washers, nuts etc.) have undergone special surface treatment.

Such parts must not be replaced by conventional parts.

NOTE: Damaged parts lose this protection and must be specially coated or replaced.

Damage caused by contact corrosion is excluded from the warranty.

Surface corrosion or pitting occurs.

A separate tool set is available for processing/machining aluminum.

Soldering is not permitted for joining aluminum components.

Risk of corrosion from chemical factors.

This results in surface corrosion.

Erection of protective barriers.

1.3 Machining properties

Properties of aluminum compared with steel Effects
Aluminum parts are magnetically neutral.

Elasticity is only 1/3 as high.

Elongation failure is approx. 50 % slighter.

Electrical conductivity is almost 4 times higher.

Material expansion during heating is twice as high.

Thermal conductivity is 3 times higher.

Structural transformation between 200 ºC and 250 ºC

Aluminum shows no annealing colors.

Attachment with magnetic tools/working aids is not possible.

Convertibility is limited in comparison with steel.

Overstretching the material results in strain-hardening and an increased tendency of cracking.

Electric welding methods require different equipment (MIG welding).

The material expands more markedly. Shorter heat treatment is necessary for removing dents.

Heat is drained more quickly. Adjoining working areas are affected more heavily e.g. during welding.

Elongation characteristics and thus plasticity are improved.

Strength is reduced.

IMPORTANT: No heat treatment during repair work on the vehicle structure! Workshop operation doesn't make it possible to control the temperature to sufficiently exact levels.

The melting point is 650 ºC. Once the melting temperature has been reached, the material begins to flow without any further indications.

The temperature can only be estimated by means of the paint coloring and the surface warpage.

IMPORTANT: Do not use thermo crayons. Not suitable for workshop operation because the paint runs too quickly.

1.4 Storage

Characteristic features of aluminum Special measures
Corrosion (ageing) in damp environments.

Contact corrosion in event of contact e.g.

with steel components.

Susceptibility to paint infiltration.

Store aluminum components in a dry place.

Always store aluminum components separately or in isolation from steel components.

Do not damage factory protective layer of the surface since this would cause oxidation.

Failure to comply with this requirement would result in more painting work.

Notes for repairing aluminum rims

In general, the economic viability must be checked prior to the repair.

It is possible to repair the following damage (applies to cast aluminum rims labelled as AlSi7 AlSi11, AlSi12):

  • Depth of the damage in the aluminum at maximum 1 mm
  • Distance of the damage from the outer rim edge at maximum 50 mm
  • Paintwork damage on the remaining wheel rim

It is not possible to repair the following damage:

  • Deformation and cracks
  • Polished, forged aluminum wheel rims are unsuitable for repair.

Body+and+Frame

An individual solution is required for damage that was not caused by an accident.

Notes on using temperature-controlled infra-red radiators

When using temperature-controlled infrared radiators, damage to adhesive bonds, paint and vehicle components can occur when drying spatula and filler.

The temperature sensors in the infrared radiator only operate reliably on large, even surfaces.

On small surfaces such as C-pillars or sills, often only a colder, adjacent area is measured.

This leads to actual surface temperatures of up to 130ºC, even if only 70ºC is set on the infrared radiator.

When the rear side walls are partially replaced by bonding and riveting, these high temperatures can lead to a visible pattern in the area of the joint.

Remedy: Check the surface temperatures on small component surfaces during the drying process with an external temperature sensor.

The general rule is: The surface temperatures must not exceed 85ºC.

IMPORTANT: Do not use infrared radiators on carbon parts! Risk of component destruction.

Opening bonded connections

4. Opening bonded connections on carbon-fibre-reinforced plastic parts Procedure is described in detailed in the relevant repair instructions.

OPENING BRAZED CONNECTIONS

The "Bonding and Riveting" repair method involves replacing the watertight brazed connection with adhesive.

This gives rise to a new procedure for opening brazed connections.

Grind brazed seam with a belt grinder. This keeps the influence of heat in the area around the brazed seam as small as possible.

IMPORTANT: Never use a gas flame.

All traces of brazing solder do not have to be removed.

Do not grind body panels thin.

Opening rivet connections

Different rivet types are used on BMW vehicles.

1. Opening blind rivets:

1.1 Loosening blind rivets (N1, N2, N7, N8, N9 and N10): Grind off blind rivet head with a belt or angle grinder. Do not grind off base material. Remove rivet remnants with a drift punch.

1.2 Opening blind rivets (N3 and N6): Drill out blind rivet head with a 5 mm dia. drill bit. Do not damage base material. Remove rivet remnants with a drift punch.

2. Opening punch rivets:

2.1 Opening punch rivets by extraction: This procedure is used on the reduced-weight aluminum front end.

Recommended tools and equipment:

  • Stud welding apparatus with gas bottle containing inert gas (82 % argon, 18 % CO2).
  • Stainless steel stud (sourcing reference via BMW Parts Department image board Aluminum and steel/bonding and welding)
  • Universal riveting tool

Grind off paint and dark grey coating of punch rivets.

Position bolt centrally on the rivet and weld on vertically. The area in which the bolts are welded on should be between the two grounding terminals. Position both terminals, if possible, on the top side of the panel on which the rivet is located.

Extract bolt with welded-on rivet using universal riveting tool. Use a large plastic nose piece if not otherwise specified in the repair instructions. Check plastic nose piece prior to use for wear.

Plastic nose piece must rest on sheet metal all round; if necessary, grind off plastic noise piece in collision area.

Do not push riveting tool forcefully onto special-steel bolts.

Do not use riveting tool to bend special-steel bolts.

Pay particular attention to central positioning of the bolt when using the small plastic mouthpiece.

Follow the equipment manufacturer's instructions for use.

2.2 Opening punch rivets by drilling out: Drill out rivets with a 6 mm dia. carbide drill bit.

Punch rivets can be drilled out on both sides. When drilling from the protruding rear side, spot-drill the rivet shank only and remove the rest with a rivet punch.

NOTE: Sand down and even out remaining burr on the rear side. Deburr bore holes.

Use a drift punch to remove punch rivet remnants in the aluminum (risk of corrosion).

Clean vehicle to remove swarfs (risk of corrosion).

Opening welded connections

1. Components made of steel:

1.1 Opening welding spots (resistance pressure spot welding): Sheet steel panels made from high- and super-high-strength materials make great demands on the tools used.

Only with special carbide milling cutters can welding spots be drilled out on these sheet panels.

Use BTR/BOR milling cutters only in conjunction with Vario Drill spot-weld remover. Sourcing reference for spot-weld remover and BTR/BOR milling cutters.

  • Procedure: If necessary, surface-grind existing unevenness with a belt or angle grinder in the area around the welding spot.

    Set punch mark in center of welding spot. Set 8 mm dia. welding spot drill bit on punch mark and drill through top metal sheet.

NOTE: Because the welding spots may have surface-hardened, grind them if necessary with an angle grinder and paper grinding disc.

Use a chisel to separate the sheet metal flange and remove the component.

Follow the special procedure for SPOT WELDS.

1.2 Opening MAG weld seams and MIG brazing seams:

  • Procedure: Grind off weld seams with a belt or angle grinder. Do not grind the base material thin.

Position of shaped parts for cavity sealing

Cavity sealing is carried out in specific body areas in order to reduce interior noise and to reduce condensation.

To do this, shaped parts are inserted in the cavities. These shaped parts adapt themselves optimally due to heating of the body to approx. 180 ºC by expansion to the shape of the cavities.

Because it is not possible to heat the body to this extent for a body repair, a different procedure .

Punch rivets

The "Bonding and Riveting" repair method involves the use for the first time of punch rivets in the repair. This requires new tools and procedures.

The punch rivets are matched in size to the material thickness and quality used at the respective connection point.

1.0 Recommended tools and equipment

  • Punch rivet tool (05 03 09 (535))

Setting punch rivets:

  • Refer to the vehicle-specific repair instructions for the punch rivet size.
  • Mark the positions of the rivets on the vehicle. Set punch rivets at roughly equal spacings.

    Punch rivets do not require a predrilled hole. They are pressed directly into the full material.

  • Insert punch rivet in riveting die. Position punch rivet tool on sheet metal parts to be riveted.

    Riveting direction: Always from new part to used part.

    Deviations are specified in the vehicle-specific repair instructions.

  • Rivet punch rivets with punch rivet tool. In the meantime clean riveting die and matrix if fouled with adhesive.
  • Seal punch rivets in moist area (e.g. wheel arch or carrier support) on both sides with SEALANTD1 (risk of corrosion).
  • Seal cavities after painting vehicle with CAVITY SEALANT (risk of corrosion).

Quality standard

  • The overall requirements relating to a vehicle can only be implemented by including "all" components.

    This applies in particular to the body. With regard to an optimum crash result, it is necessary to maintain the structural measures.

    The procedures described in the repair instructions must be complied with. Deviations are only permitted after arrangement with and approval by BMW.

    The use of non-approved repair steps or tools may have serious consequences for the structure of the vehicle (e.g. in the event of a crash). In the end, this can result in safety and product liability risks which cannot be calculated.

    Corrosion protection measures during and after repair work are vital for ensuring the vehicle retains its value.

  • For repair work, only use original BMW/MINI parts, or parts that are of an equivalent quality, and approved auxiliary materials and operating fluid.

    For repairs that are settled by a warranty or goodwill, only original BMW/MINI parts may be used.

SITUATION

BMW/MINI vehicles are subjected to rigorous crash tests by internal BMW/MINI departments, government agencies and additional crash assessment tests by independent organizations. When repairs are required, the only way to guarantee that a vehicle will retain and fulfil all crash requirements following repairs is to follow BMW/MINI repair standards and use only new original BMW/MINI parts. Any deviation could have serious consequences on the crash performance of the vehicle and jeopardize the safety of the occupants.

BMW/MINI utilizes many different types of materials and joining methods during production of the body shell.

The advanced steels, aluminum and synthetic materials are used to improve weight, strength, energy absorption and corrosion resistance. These materials work in unison with the rest of the vehicle to deliver the level of safety, driving performance and appearance often associated with the BMW/MINI brand.

PROCEDURE

BMW/MINI of North America does not support the use of aftermarket, imitation, recycled and salvage repair parts. Returning BMW/MINI vehicles to manufacturer's specifications requires trained technicians utilizing only approved equipment, materials and joining processes. BMW/MINI repair instructions are supported only by the use of new original BMW/MINI parts.

BMW/MINI of North America bases its considerations on the following points:

  • It cannot be confirmed that equivalent materials are used to produce aftermarket parts.
  • All crash testing results and certifications are achieved with original BMW/MINI parts and joining methods in place.
  • It cannot be confirmed that remanufactured components from outside sources fulfil BMW/MINI repair standards.
  • Salvage components cannot be traced if subjected to a manufacturer's recall.
  • It cannot be confirmed that salvage parts have not been subjected to prior crash impact loads, previous repair work, weathering and/or exposure to additional elements such as fire, smoke/heat damage or flooding.
  • Non-original BMW/MINI parts may have poor fit, finish and quality which has a direct impact on the residual value of the vehicle. Original BMW/MINI parts are the same parts utilized to build the vehicles.

Handling electrical system, electronics, airbags and restraint systems .

1. General information

  • For repair cases the following procedure will implemented:
    • Autogenous brazing solder
  • The MIG soldering procedure is not used in repairs for strength reasons. MIG soldered/brazed seams used in standard production are replaced during repairs by MAG weld seams.
  • Brazed areas from vehicle production are bonded following the same procedure.

2. Work materials

  • Tube pack and torch (autogenous torch)
  • Brazing solder
  • Gas bottles (oxygen and acetylene)
  • Welding goggles

3. Preparation

  • Remove the paint and zinc layer in an area of approx. 30 mm around the seam to be soldered.

4. Implementation

  • Execute brazed seam without overheating the solder and with low heat dissipation. If necessary, use heat protecting paste.

5. Subsequent treatment of brazed connections:

  • Remove burnt residual zinc completely. Align and grind visible connection faces.
  • Remove burnt paint with a stainless steel wire brush.

6. Notes on melting/tinning: Only applicable within the European Union! European used-vehicle regulations prohibit the use of tin containing lead in motor vehicles introduced after 01.07.2003! Even out unevenness smaller than 2 mm with filler according to painting handbook If an exceptional unevenness is larger than 2 mm, use METAL FILLER.

Only perform in visible areas of the outer skin and on the carrier support.

All areas which have covers on the vehicle are not to be processed.

Spot-weld bonding steel components

IMPORTANT: Comply with the following topics from "Body, General": Safety regulations .

Handling electrical system, electronics, airbags and restraint systems .

  • Beginning with E65 the spot-weld bonding process is used to increase vehicle rigidity. In partial body areas, a 1-component adhesive is applied to the spot flanges and this is followed by resistance pressure spot welding. The adhesive is hardened only after the paint drying process (at approx. 180 ºC).
  • In the case of repairs, adhesive is not applied to the spot flanges. The number of welding spots is doubled as a substitute for the omitted adhesive.
  • Minimum distance between welding spots (1) is 25 mm. Important! The minimum distance must not be undershot! If there is not enough space for twice the number of resistance weld points, each non-made resistance weld point must be replaced by a MAG weld seam (2). Length of a MAG weld seam = 20 mm.

    Set the MAG weld seams at equal intervals distributed on the face.

Body+and+Frame

  • The following procedures are used as a substitute for spot-weld bonding:
    • MAG welding (M etal A ctive G as welding)
    • Resistance pressure spot welding (referred to in the following and in the repair instructions as spot welding).
  • Adhesive is not applied between the spot flanges on new parts in the case of 2- or multi-sheet joints.

    Areas which cannot be reached by the spot-welding tongs can be joined by MAG plug welding. The number of welding spots is doubled as a substitute for the omitted adhesive.

  • Exceptions (e.g. E65) are described in the relevant repair instructions. Apply welding spots to existing welding spots on new part. This is necessary because the adhesive between the spot flanges of the new part acts as an insulator.

CAUTION: Extract smoke and fumes during welding work.

Spray gun for cavity sealant

Body+and+Frame

1.0 Delivery specification:

  • Owner's Handbook
  • Pressure reservoir spray gun (1) for cavity sealant
  • Spray set, consisting of spray hoses: Angle nozzle (2) and round spray nozzle (3)

IMPORTANT: Prior to start-up read and familiarize yourself with the manufacturer's operating and safety instructions.

2.0 Start-up:

  • Open the pressure reservoir and insert the cavity sealant in the form of a 1-liter can.

    Close the pressure reservoir.

  • Connect the spray hose to the quick-release coupling.
  • Connect the device to the compressed air supply.

    Operating pressure 2-6 bar, max. 8 bar!

3.0 Operating principle:

NOTE: Unlike previous devices you can alter the spray pattern on this device with the air volume regulating screw (large knurled screw).

  • Twisting the air volume regulating screw in decreases the air volume and thus reduces the formation of material mist.

This facilitates optimum working when preserving open components/surfaces.

  • Twisting the air volume regulating screw out increases the air volume and thus increases the formation of material mist. (For closed cavities)
  • The trigger has two settings.

    1st setting - air discharge only.

    2nd setting - air and material discharge.

  • After finishing work, press the first setting to clean the spray hose with compressed air.
  • Prior to storing, remember to twist the air volume regulating screw closed to reduce the risk of the material drying out.
  • Prior to an extended period of non-use (2 weeks and more), clean the gun.
  • To ensure that the spray hoses function properly, do not store them coiled up e.g. in the side member area! Store the spray hoses stretched out.

4.0 Application examples:

  • Use the appropriate spray hoses for the different types of cavity and surface.
  • Example - doors, lids and hatches: Spray hose with angle nozzle. Reduce air volume to keep the formation of mist low.
  • Example - side members: Long spray hose with round spray nozzle. The air volume must be increased a little, depending on the type used.
  • Basically, keep the formation of mist low to avoid fouling and unpleasant odors.

5.0 Safety instructions:

  • Do not inhale spray mist.
  • Use in well ventilated rooms only.
  • Operating pressure max. 8 bar.

Straightening aluminum component on the outer skin

1.0 Prerequisites

The component must be replaced if there are cracks and it is neither possible to drill into the end of the crack, nor to weld it.

2.0 Recommended tools

  • Only use tools specifically designed for aluminum repairs.
  • Do not use tools and operating fluids that have already been used for steel repairs (e. g. grinding wheel). Danger of contact corrosion.
  • Do not use any sharp-edged tools (notch effect).

3.0 Straightening outer skin

  • "Cold" straightening: Press dents out from their center and smooth in an outwards direction with gentle taps.

    In the case of small, soft dents (hail and parking damage), this is also possible without damaging the paintwork. Special tools and a trained employee are needed.

  • "Hot" straightening: Heat the component in the damaged area with a hot air blower to approx. 60 Â ºC. This significantly reduces the force that needs to be applied for straightening.
  • Avoid notching and cracking.
  • Avoid hardening and overstretching.
  • Avoid heating and excess temperature the outer skin over large areas.

Straightening aluminum components in structure

  • Reshaping or heating extruded profiles and cast parts is not permitted! Failure to comply with this requirement would have the following results:
    In the case of reshaping, weld seams (E52) or bonded connections (E60, E61, E63, E64) tear in the surrounding area.

    In the case of reshaping, the material loses up to 40 % of its original strength.

    In the case of heating, the material loses up to 40 % of its original strength.

    The adhesive is destroyed at temperatures ≥120 ºC (E60, E61, E63, E64).

    Extruded profiles and cast parts which show visible or measurable signs of deformation must be replaced.

    Perform the check for deformation with the aid of the straightening system.

    For optical testing, strip adjoining components in cases of doubt.

    Extruded profiles are used in the E52 as engine supports, door posts, side members, etc.

    Extruded profiles are used in the E60, E61, E63, E64 as engine supports.

    Cast parts are used in the E60, E61, E63, E64, E70, E71 as spring supports.

  • Reshaping of extruded profiles and cast parts may only be used to achieve optimum joining of connection faces (e.g. when bulkhead is damaged). Reshaped parts must be replaced.

    Repairs which affect the attachment points of mechanical assemblies and chassis/suspension components must be carried out on the straightening bench. Use the vehicle-specific set of attachments set or vehicle- specific data sheet.

    Straightening attachment supports and data sheets are also available for the top section, e.g.: door posts, soft top mounts, cowl panel, tailgate hinges, etc.

  • Check windscreen and rear window apertures for curvature by inserting the original glass.
  • Take the gap dimensions for doors, engine compartment lid and tailgate from the vehicle-specific gap dimension diagram.
  • Exceptions on the E60, E61, E63, E64:
    Carrier support and bulkhead may be straightened if they do not have any cracks, sharp-edged damage or holes. After repair work, check parts again for cracks.

    Examine adjoining adhesive flanges for peeling off. If necessary, seal and preserve with SEALANT.

    Observe the frame reference dimension for the carrier support.

    Any repairs to the bulkhead if cracked outside the approved scope of repair work are only permitted after consultation with and approval by BMW.

Straightening steel components in the structure

  • High-strength and super-high-strength steel plates as a rule cannot be reshaped. Reshaping only serves as a preparatory measure to replacing the component in order to achieve optimal joining of the connection points.
  • Bearing body components such as e.g. engine supports, door pillars, side members etc. with deformations which can no longer be returned to their original shape by "cold straightening" must be replaced.
    Heating bearing body components for better reshaping is not permitted! Failure to comply with this requirement would result in a loss of original strength of up to 40 %.
  • The body must be anchored as follows for reshaping:
    If using vehicle-specific/universal straightening attachment sets (Carbench/Celette/Car-O-Liner), it is necessary to secure the body additionally with 4 retaining clips to the spot flange of the entrance or to the 4 jacking points. The spot flange (if available) is to be preferred.

    If using universal electronic or mechanical straightening systems (Car-O-liner/Celette), it is necessary to secure the body with 4 retaining clips to the spot flange of the entrance or to the 4 jacking points. The spot flange (if available) is to be preferred. In addition anchor at least 2 points with the securing set.

    Failure to comply with these instructions will result in damage to the body during reshaping in non- damaged areas. Vehicle-specific straightening attachments and universal mounts may be damaged.

  • Repairs affecting the mounting points of assemblies and chassis/suspension components must be carried out on the straightening bench with the matching straightening attachment set or specification sheet for the vehicle.

    Straightening attachments and specification sheets are also available for the top section, e.g.: door pillars, convertible top mounts, cowl, rear lid hinges, etc.

  • Check windshield and rear window apertures for curvature by inserting the original glass.
  • Take the gap dimensions for doors, engine hood and rear lid from the vehicle-specific gap dimension diagram.

Straightening steel components on the outer skin

1.0 Recommended tools.

Only use those tools designed for steel repairs.

2.0 Straightening outer skin.

  • "Cold" straightening: Press dents out from their center and smooth in an inwards direction with gentle taps.

    In the case of small, soft dents (hail and parking damage), this is also possible without damaging the paintwork. This requires special tools and a trained employee.

  • In the case of damaged areas which are only accessible from one side, a repair system with welding can be used.
  • Avoid cracking.
  • Avoid hardening and overstretching.
  • Prevent overheating small areas of the outer skin.
  • When the surface exhibits an unevenness no greater than 2 mm after straightening, putty compound can be used to even out the area (see Painting Handbook).

    Unevenness greater than 2 mm with metal putty.

NOTE: Only applicable within the European Union!

European used-vehicle regulations prohibit the use of tin containing lead in motor vehicles introduced after 01.07.2003!

  • For high-security vehicle, note the special information in the repair instructions!

2.1 Straightening the wheel arch (rear side panel). Vehicles in which the wheel arch is not welded but bonded and bordered can be straightened.

This is possible in the following situations:

  • Rear side panel (wheel arch) is not torn in the area of the bonding. Welding in this area is not permissible.
  • The outer skin has not become separated from the outer wheel arch section.

In general, the following applies: When performing straightening work on the wheel arch, apply sealant to the inside. After straightening, the area must be primed and resealed with sealant D1. Protect from the inside using cavity preservation.

Touching up paintwork damage

These notes apply to paintwork damage on the body aperture that occurred when detaching bonded window glass.

To ensure long-term corrosion protection, it is absolutely essential to touch up damage to paintwork! The "BMW Color System" painting handbook forms the basis of these repair instructions and must be observed without fail.

Ground down damage to paintwork on body aperture and touch up with BMW multibase filler.

Grind larger areas or damage down to the bare sheet metal and coat with BMW multibase filler (layer thickness 30 to 40 μm).

Hardening time:

  • With infrared, at least 10 minutes
  • Without infrared for at least 60 ºC, at least 30 minutes
  • Without infrared for at least 20 ºC, at least 24 hours

If a complete build-up of paint is required in the visible area:

  • Tape off primed adhesive flange before applying top coat

IMPORTANT: Observe hardening time of BMW multibase filler otherwise a perfect bond cannot be guaranteed!

Vehicle identification number, general

In the event of repair 2 procedures are used, depending on the vehicle. Refer to the vehicle-specific repair instructions for the correct procedure.

1. General notes for stamped vehicle identification numbers:

The vehicle identification number is stamped with a special tool. There are different special tool numbers and stamping procedures for the various vehicles. Refer to the relevant repair instructions.

In repair work, the vehicle identification number is always stamped into a replacement vehicle identification number surface. The replacement surface is usually situated under the original VIN surface.

The IGEF number (bodyshell number) is omitted when the wheel arch is replaced.

In the event of component or body replacement by the BMW garages/workshops, clearly delimit the vehicle identification number at front and rear by stamping a + in place of the BMW badge.

If a VIN is stamped into the replacement surface in addition to the original VIN (e.g. if the original VIN has been tampered with), the following applies: The original VIN must be crossed out. To do so, stamp the letter I from the punch digits lengthways through the original VIN.

IMPORTANT: Do not use an angle grinder in conjunction with a cutting disk!

The protective film used as standard is omitted after the VIN has been manually stamped in. Paint area in accordance with BMW Painting Handbook. Ensure that layer thicknesses are small.

Observe national/country-specific regulations.

2. General notes for embossed vehicle identification numbers:

This procedure is used for all vehicles on which the vehicle identification number can not be stamped.

For the repair new parts with an embossed vehicle identification number can as a rule be ordered from the BMW Parts Department. If this is not possible, observe country-specific regulations.

The IGEF number (bodyshell number) is omitted when the wheel arch is replaced.

If a VIN is embossed into the replacement surface in addition to the original VIN (e.g. if the original VIN has been tampered with), the following applies: The vehicle-specific repair instructions describe the procedure.

The protective film used as standard is omitted after the VIN has been embossed. Paint area in accordance with BMW Painting Handbook. Ensure that layer thicknesses are small.

Observe national/country-specific regulations.

Welding steel components

IMPORTANT: Comply with the following topics from "Body, General": Safety regulations .

Handling electrical system, electronics, airbags and restraint systems .

1. General information

  • The following procedures are used for repairs:
    • MAG welding (M etal A ctive G as welding)
    • Resistance pressure spot welding (referred to in the following and in the repair instructions as spot welding).
  • Take the number and position of welding spots and MAG weld seams from the separated part.

    Replace areas inaccessible to spot-welding tongs with MAG plug weldings at the same distance.

    Diameter of bore holes for plug weldings 8 mm.

  • In the case of emissions extraction, observe a minimum distance of 30 cm for MAG welding during the welding process. Otherwise the inert gas would be drawn off.
  • Follow the equipment manufacturer's instructions for use.

2. Work materials

  • MAG welding:
    • Steel welder (see WORKSHOP EQUIPMENT).
    • Steel welding wire - G3SI1 (SG2) or alternatively G4SI1 (SG3)
    • Welding mask
    • Gas bottle containing inert gas (82 % argon, 18 % CO2)
  • Resistance pressure spot welding:
    • Spot-welding apparatus (see WORKSHOP EQUIPMENT).
    • Safety goggles

3. Preparations for MAG and spot-welding

  • Remove the paint coating in an area of approx. 30 mm around the weld seam or spot.
    • The zinc layer underneath must be removed during the MAG welding method.
    • It is not necessary to remove the zinc layer underneath during spot-welding.
  • Remove the paint coating on the reverse side of the weld seam or spot.
    • Contaminants will otherwise enter the weld pool via the root of the weld seam.
    • An insufficient electron flow prevents an optimum spot-weld joint.
  • Coat all metal overlaps and weld spot flanges with welding primer.
  • To determine the optimum electrode contact force for spot-welding, carry out spot-weld shear tests on sample sheet metal.
  • In order to keep the electron flow short during MAG welding on the body, you must if possible attach the ground terminal directly to the component to be welded.

4. Welding

  • During MAG welding, the weld gap must be kept as small as possible. The larger the weld gap, the lower will be the strength of the joint.
  • During spot-welding, the sheet metal flanges to be joined must be placed as close together as possible without gaps.

    The larger the gap, the lower will be the strength of the joint.

    Minimum distance between welding spots 25 mm.

5. Subsequent treatment of welded connections:

  • When grinding a weld seam, do not grind thin the base material next to the seam.
  • After joining, clean all weld seams and spots with a stainless steel wire brush.
  • Remove burnt paint with a stainless steel wire brush.
  • All welded connections sealed off with body sealing compound in original condition must be primed and sealed off again thoroughly after repairing. Replace damaged or removed anti- drumming layers.

Working with 2-component PU cavity foam

Properties of cavity foam:

  • 2-component PU foam, solvent-free.
  • Excellent flow capacity, enabling complete sealing of cavities.
  • Good strength, preventing slipping in cavities.
  • Low water absorption, preventing corrosion.
  • Ideal for use as insulating and sealing compound

Information on dangers/hazards:

  • Avoid eye and skin contact.

    Wear protective goggles, solvent-resistant protective gloves and protective clothing.

  • Do not inhale.

    Apply in well ventilated rooms only.

WARNING: Application time after mixing: within 8 minutes!

  • Completely empty open can after use.
  • Remaining amounts which are not used can cause the can to explode on account of a chemical reaction (buildup of heat)!
    Alternatively, cool the can containing the non-removed remaining amount for several hours in cold water.
  • Do not eat, drink or smoke during this operation.
  • Keep heat and ignition sources well away.
  • Read the manufacturer's information on hazards/dangers (printed on the can) prior to application.

Application instructions:

  • Use by date on can.

    Do not use the spray can after the Use by date on the can has expired. After the Use by date the properties of the cavity foam will no longer meet the requirements of the BMW Group.

  • Cavity sealing of repair area possible after an air drying time of 1 hour.
  • Backing surface must be clean and free from dust, grease, oil and stripping agent.
  • Application temperature at least 15 ºC. Optimally 20 ºC.
  • Remove fresh, non-hardened PU foam with adhesive cleaner 208.

    Sourcing reference: BMW Parts Service.

    Hardened PU foam can only be removed by mechanical means (machine).

  • Excess, hardened PU foam can be disposed of as residual waste.

    Cans which are not entirely empty and unused whose Use by date has expired are classed as hazardous waste.

    Observe country-specific waste-disposal regulations.

  • Observe the manufacturer's application instructions (printed on the can).

IMPORTANT: Foam expands many times over as it sets (change in volume).

  • Setting takes approx. 30 minutes. Mechanical processing (e.g. drilling, cutting, etc.) is then possible.
