Contact Corrosion

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2017 Audi S3, 2017 Audi RS 3, 2017 Audi A3 Quattro, 2016 Audi S3, and 2016 Audi A3 Quattro. 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.

For this reason, only fasteners with a special surface coating are installed.

Rubber or plastic parts and adhesives are also 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.

Only original replacement parts are recommended. They are checked and compatible with aluminum.
The use of Audi accessories is recommended.
Contact corrosion damage is not covered under warranty.
