Brakes and Traction Control: Service Precautions


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

For this reason, only fasteners with a special surface coating are installed (Dachromet). These elements are distinguished by their greenish hue.

Furthermore, all rubber, plastic and adhesive materials used are non-conductive.

If you have doubts about the reusing parts, it is generally better to install new parts.

Note the information:
Use only Audi authorized parts! They have been tested and are compatible with aluminum.

Additional equipment must be authorized by Audi AG!
Damage via contact corrosion is not covered by warrantee!
