Contact corrosion

~1min read

Contact corrosion can occur if unsuitable fasteners (bolts, nuts, washers, etc.) are used. Therefore, only fastening elements with a special surface coating are installed in the vehicle. In addition, rubber and plastic parts as well as adhesives are made of electrically non-conductive materials. If there is any doubt about the suitability of parts, a general rule is to use new parts → Electronic Parts Catalogue.

Please observe the following:

Use only Genuine replacement parts which are tested and compatible with aluminium.

Use only Volkswagen Genuine Accessories.

Damage due to contact corrosion is not covered by warranty.
