Contact Corrosion
WARNING: This page is about a different car, the 2012 Audi S5, 2011 Audi S5, 2010 Audi S5, 2009 Audi S5, and 2008 Audi S5. 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 are made of non-conductive materials.
If there are doubts about whether parts can be used or not, then use new parts.
NOTE:
We recommend Original Parts only. They are tested and compatible with aluminum.
The use of Audi accessories is recommended.
Contact corrosion damage is not covered under warranty.
