Contact Corrosion
WARNING: This page is about a different car, the 2015 Audi Q5, 2014 Audi Q5, and 2013 Audi Q5. However, it is still accessible from the selected car via links, so may be relevant.
Contact corrosion can occur if unsuitable fasteners (bolts, nuts, washers, etc.) are used.
For this reason, only fasteners with a special surface coating may be installed.
In addition, rubber or plastic parts and adhesive are made of materials that do not conduct electricity.
If there are doubts about whether parts can be used or not, then use new parts .
NOTE:
Original replacement parts are recommended because they have been tested.
The use of Audi accessories is recommended.
Damage resulting from contact corrosion is not covered by the warranty.
