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 incorrect fasteners (bolts, nuts, washers, etc.) are used.

In addition, rubber or plastic parts and adhesives are made of non-conductive materials.
If there are doubts about whether parts can be used or not, then use new parts. Refer to the Parts Information.
Note:
- The use of Audi original replacement parts is recommended, since they are tested and approved.
- The use of Audi original accessories is recommended.
