| Contact corrosion can occur if unsuitable fasteners (bolts, nuts, washers ...) are used. |
| For this reason, all the fasteners on the vehicle have a special surface coating (Dacromet). These components can be recognised by their greenish colour. |
| In addition, rubber parts, plastic parts and adhesives are made of non-conductive material. |
| Always install new parts if you are not sure whether used parts can be refitted. |
| Always use genuine parts. These have been tested and are compatible with aluminium. |
| Accessories must be approved by AUDI AG. |
| Damage resulting from contact corrosion is not covered under the warranty. |
