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.
