I recently bought an A3 1.6 FSI 2004 with 81,000 miles and whilst driving it home, the engine light came on.

Now the airbag light has come on too. I took it to Audi (when it was just the engine light) and they said it was some sort of faulty wire in the ECU, and that it would cost over £500 to fix!

Searching these forums, i've noticed a few A3's have had similar problems, and its down to the CTS. But Audi didnt say anything about this.

Any suggestions or help about either lights???
