WARNING

It is recommended to have a special aluminium tool kit in the
workshop trolley.
5.5.4 Contact corrosion
Contact corrosion can occur if unsuitable fasteners (bolts, nuts,
washers etc.) are used. For this reason, only fasteners with a
special surface coating are fitted. In addition, all rubber parts,
plastic parts and adhesives are made of non-conductive materi‐
als. Always renew parts if you are in any doubt as to whether the
old part can be used again.
Note
♦
Always use genuine replacement parts (same as original
equipment). These have been tested and are aluminium-com‐
patible.
♦
Accessories must be approved by Volkswagen AG.
♦
If non-approved materials are used, any damage caused by
contact corrosion is not covered by warranty.
