Contact Corrosion
WARNING: This page is about a different car, the 2022 Audi S3, 2022 Audi RS 3, 2022 Audi A3 Quattro, and 2022 Audi A3. However, it is still accessible from the selected car via links, so may be relevant.
Contact corrosion can occur if inadequate fasteners (bolts, nuts, washers, etc.) are used.
For this reason, only fasteners with a special surface coating may be installed.
Furthermore, only rubber/plastic parts and adhesive made of electrically non-conductive materials are used.
If there are doubts about whether parts can be used or not, use new parts. Refer to the Electronic Parts Information (ETKA).
Note:
- Only original replacement parts are recommended. They are checked and are compatible with aluminum.
- The use of Audi accessories is recommended.
- Contact corrosion damage is not covered under warranty.
