Contact Corrosion
WARNING: This page does not describe the selected car, but rather 23 other vehicles, including the 2017 Audi S5, 2017 Audi A5 Quattro, 2016 Audi S5, 2016 Audi A5 Quattro, and 2015 Audi S5. However, it is still accessible from the selected car via links, so may be relevant.
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!
