Contact Corrosion

Contact corrosion can occur when incorrect fasteners (bolts, nuts, washers, etc.) are used.

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

In addition, rubber and plastic parts and adhesive are of non-conducting materials.

If there are doubts as to whether parts should be reinstalled, install new parts.

Only use genuine Audi replacement parts. They have been checked and are compatible with aluminum.

Accessories must be approved by Audi AG.

Damage due to contract corrosion is not covered under warranty!
