Contact corrosion!
Contact corrosion!
Contact corrosion can occur if unsuitable fasteners are used (e.g. bolts, nuts, washers, etc.).
For this reason, only fasteners with a special surface coating are used.
Additionally, all rubber and plastic parts and all adhesives are made of non-conductive materials.
Always install new parts if you are not sure whether used parts can be re-fitted → Electronic parts catalogue.
Note the following:
t  Use only genuine parts that have been tested and are compatible with aluminium.
t  Use only Audi Genuine Parts.
t  Damage caused by contact corrosion is not covered under warranty.
