Lighting and Horns: Service Precautions

Contact Corrosion

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

For this reason, only fasteners with a special surface coating are used.

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

If there are doubts as to whether parts are suitable or not, use new parts. Refer to the Electronic Parts Catalog (ETKA).

• We only recommend original replacement parts as they have been tested and are compatible with aluminum.

• We recommend using genuine Audi accessories.

• Damage resulting from contact corrosion is not covered by warranty.
