Contact Corrosion
WARNING: This page does not describe the selected car, but rather 13 other vehicles, including the 2017 Audi SQ5, 2017 Audi Q5, 2016 Audi SQ5, 2016 Audi Q5, and 2015 Audi SQ5. However, it is still accessible from the selected car via links, so may be relevant.
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 consist of non-conductive materials.
If there are doubts as to whether parts can be reused or not, use new parts.
NOTE:
The use of original replacement parts is recommended, they are tested and are compatible with aluminum.
The use of Audi accessories is recommended.
Contact corrosion damage is not covered by warranty!
