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