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 or plastic parts and adhesive are made of non-conductive materials.

If there are doubts whether a part should be used again, install a new part according to the Parts Catalog.

We recommend only using original replacement parts, they have been tested and are compatible with aluminum.

We recommend using Audi accessories.

Damage due to contract corrosion is not covered under warranty!
