Contact Corrosion
WARNING: This page is about a different variant/trim than selected.
Contact corrosion can occur when incorrect fasteners (bolts, nuts, washers, etc.) are used.
For this reason, only fastening elements with a special surface coating (Dacromet) are installed. These elements can be recognized by their green color.
In addition, rubber and plastic parts and adhesive are of non-conducting materials.
If there are doubts as to whether parts should be reinstalled, install new parts.
NOTE:
Only use Original Parts. They have been checked and are compatible with aluminum.
Accessories must be approved by Audi AG.
Damage due to contract corrosion is not covered under warranty!
