Contact corrosion
Contact corrosion
Contact corrosion can occur if use is made of unsuitable connecting elements, bolts, nuts, packing plates, rivets, plugs, grommets, adhesives, etc.
For this reason, only connecting elements with a special surface coating are fitted at the factory. In addition, rubber components, plastic components and adhesives are made of non-conductive materials. These tested, aluminium-compatible components are also available as replacement parts → Electronic parts catalogue.
Important:
t  Always fit new parts in cases of doubt about reusability.
t  We recommend the use of genuine replacement parts only, as these have been checked and are compatible with aluminium → Electronic parts catalogue.
t  We advise using Audi accessories → Electronic parts catalogue.
t  Damage caused by contact corrosion is not covered by warranty.
