Contact Corrosion
Contact corrosion can occur if incorrect fasteners (bolts, nuts, washers, etc.) are used.
For this reason, only fasteners with a special surface coating are installed.
Rubber or plastic parts and adhesives are also made of non-conductive materials.
If there are any doubts as to whether parts can be reused or not, use new parts. Refer to the Parts Information.
NOTE:
The use of original replacement parts is recommended, since they are tested and are compatible with aluminum.
The use of Audi accessories is recommended.
Contact corrosion damage is not covered under warranty!
