Contact Corrosion






Contact Corrosion

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

For this reason, only install connecting elements that are treated with a special coating.

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

If there are doubts about the suitability of parts, generally use new parts. Refer to the Parts Catalog.

We recommend original parts only. They are tested and compatible with aluminum.

Audi accessories are recommended.

Damage due to contact corrosion is not covered by warranty.
