Contact Corrosion

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

For this reason, only fasteners with a special surface coating are installed.

In addition, rubber or plastic parts and adhesives are made of non-conductive materials.

If there are doubts as to whether parts are suitable or not, use new parts. Refer to the Parts Information.

Note:

• Only use original replacement parts that have been tested and are compatible with aluminum.
• Use only Volkswagen accessories.
• Contact corrosion damage is not covered under warranty.
