Contact Corrosion

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

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

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

If there are doubts about whether parts can be used or not, then use new parts.

Note:

• Original replacement parts are recommended because they have been tested.
• The use of Audi accessories is recommended.
• Damage resulting from contact corrosion is not covered by the warranty.
