Can anyone give me some advice?? My Airbag light came on some time ago, and when I put it in for a service last week with Isaac Agnew Audi in Belfast, I was expecting them to say it was a sensor, or a faulty connection. However, they claim that it was the Control Unit, and it would need replaced at a cost of £370 for the part + Labour & VAT, bringing it up to around £500!! The Car is 4 years old with only 36K on the clock. Is there anywhere I could get this unit for less? Or should I be writing to Audi to complain about this unit failing so soon?
