Contact Corrosion
WARNING: This page is about a different car, the 2012 Audi S5, 2011 Audi S5, and 2010 Audi S5. However, it is still accessible from the selected car via links, so may be relevant.
Contact corrosion can occur if non-approved fasteners are used such as bolts, nuts, washers, etc.
For this reason, only connecting elements with a special surface coating are installed.
Also, rubber or plastic parts and adhesive consist of non-conductive materials.
If you are not sure about the suitability of parts, install new parts.
NOTE:
We recommend original parts only. They are tested and compatible with aluminum.
It is recommended to use Audi accessories.
Damage resulting from the contact corrosion is not covered by the warranty.
