Contact Corrosion
WARNING: This page is about a different variant/trim than selected.
Contact corrosion can occur if incorrect fasteners (bolts, nuts, washer, etc.) are used.
For this reason, install only connecting elements with a specific surface coating.
Also, rubber or plastic parts and adhesive consist of materials that do not conduct electricity.
Always use new parts if there is ever a doubt in quality.
NOTE:
Only original replacement parts are recommended as they are checked and are aluminum compatible.
The use of Audi materials is recommended.
Damage due to contact corrosion is not covered by warranty.
