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.

Furthermore, only rubber/plastic parts and adhesive made of electrically non-conductive materials are used.

If there is any doubt about whether parts can be used or not, then only use new parts. Refer to the Parts Information.

Note:

• Original replacement parts are recommended because they have been tested.
• The use of Audi accessories is recommended.
• Contact corrosion damage is not covered under warranty.
