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 and plastic parts and adhesive are of non-conducting materials.
If there are doubts as to whether parts should be reinstalled, install new parts.
Please note:
Only use genuine Audi replacement parts. They have been checked and are compatible with aluminum.
Accessories must be approved by Audi AG.
Damage due to contract corrosion is not covered under warranty!
