Contact Corrosion

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

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 about whether the parts are suitable, then use new parts. Refer to the Parts Information.

Note:

• Only original replacement parts are recommended. They are checked and compatible with aluminum.
• The use of Audi accessories is recommended.
• Contact corrosion damage is not covered under warranty.
