General Information
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.
