Audi Workshop Service and Repair Manuals

Contact corrosion can occur if use is made of unsuitable connecting elements (bolts, nuts, washers), rivets, plugs, sockets, adhesives etc.

For this reason, all the connecting elements fitted have been subjected to special surface treatment by the manufacturer. This can be seen from the greenish colour of such elements. Use is also made of rubber and plastic parts as well as adhesives which are not electrically conductive.

These tested, aluminium-compatible components are also available as replacement parts.

Always use genuine parts!

In case of doubt concerning the re-usability of parts, always fit new ones.

Accessories must be approved by AUDI AG.

Damage resulting from contact corrosion is not covered by the warranty.
