Volkswagen Golf Service & Repair Manual: Contact corrosion

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.
