SEATS

Manufacturer
Volkswagen Group of America, Inc.
What Happened
The cable connecting your car's seat heater to a safety system is a small wire that helps your passenger air bag deploy properly. In some 2017-2020 models, this wire might not make a good connection, causing the air bag to shut off when it shouldn't.
Risk if Unfixed
If your passenger air bag doesn't deploy in a crash, you or your passenger could be seriously injured. This is a critical safety risk, and you should address it as soon as possible.
Free Fix
Your Audi dealer will replace the faulty wire and either the heating mat or the entire seat cover, at no cost to you. They'll also handle any previous repairs from a related recall, and you'll receive a notification letter with instructions on what to do next.
