Contact Corrosion

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

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

In addition, rubber or plastic parts and adhesive are made of materials that do not conduct electricity.

If there are doubts whether a part should be used again, install a new part according to the Electronic Parts Information (ETKA).

• We recommend only using original replacement parts. They have been tested and are compatible with aluminum.
• The use of Audi accessories is recommended.
• Contact corrosion damage is not covered under warranty!
