Contact Corrosion
WARNING: This page is about a different car, the 2016 Audi A3 and 2015 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.
For this reason, only connecting elements with a special surface coating are installed.
In addition, rubber or plastic parts and adhesives are made of non-conductive materials.
If you are not sure about the suitability of parts, install new parts. Refer to the Parts Information.
NOTE:
Only original replacement parts are recommended, they are checked and compatible with aluminum.
Using original parts is recommended.
Damage resulting from contact corrosion is not covered by the warranty.
