Contact Corrosion
WARNING: This page is about a different variant/trim than selected.
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.
In addition, rubber or plastic parts and adhesives are made of non-conductive materials.
If there are doubts whether a part should be used again, install a new part according 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!
