Contact Corrosion

Contact corrosion
Contact corrosion can occur if non-approved fasteners are used on the vehicle (bolts, nuts, washers etc.).

For this reason, all fastening components have been subjected to special surface treatment (Dachromet). These components can be identified by their greenish surface finish.

In addition, all rubber and plastic parts and all adhesives are made of non-electrically conductive materials.

If you are not sure whether used parts can be re-installed, always install new parts.

Please note:

Always use genuine parts.

These have been tested and are compatible with aluminum.

Accessories must be approved by AUDI AG.

Damage resulting from contact corrosion is not covered by the warranty.
