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 whether parts can be reused, use new parts according to the Parts Information

NOTE:
  • The use of original replacement parts is recommended, since they are tested and are compatible with aluminum.
  • The use of Audi accessories is recommended.
  • Contact corrosion damage is not covered under warranty!
