Contact Corrosion

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

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

In addition, rubber or plastic parts and adhesive are made of non-conductive materials.

If there are doubts about whether parts can be used or not, use new parts. Refer to the Parts Information.

Note:

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