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.

Note

1. We only recommend original replacement parts, they have been tested and are compatible with aluminum.
2. We recommend using Audi accessories.
3. Damage resulting from contact corrosion is not covered by warranty.
