Contact Corrosion

Contact corrosion can occur if inappropriate fasteners (bolts, nuts, washers, rivets, plugs, grommets, adhesives etc.) are used.

For this reason, the manufacturer only installs fasteners with a special surface coating. Also, rubber and plastic parts and adhesive consist of materials that do not conduct electricity. These parts, which have been tested and are aluminum compatible, are also available as replacement parts. Refer to the Parts Information.

Note:

• Always install new parts if there is any doubt as to whether parts can be reused.
• Original equipment replacement parts are recommended. They have been tested and are compatible with aluminum. Refer to the Parts Information.
• Audi accessories are recommended. Refer to Parts Information.
• Contact corrosion damage is not covered under warranty.
