Contact Corrosion
WARNING: This page is about a different car, the 2022 Audi SQ7 and 2022 Audi Q7. 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, all rubber or plastic and adhesive are made of non-conductive materials.
If there are doubts about whether parts can be used or not, use new parts. Refer to the Parts Information.
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.
