warning lights are usually got to do with the electronics in the carm so you should go to a mechanic and ask him to check the cars electronics which is free and he will probably say your electronic wiring is smashed the cheapest thing to do is rewire your car it would cost 100-250 euro where as if you got the car comprimised it would cost 700-900 euro

I had the same issue with my '05 A4 1.8T.  Turns out it was the RPM sensor.  Audi tried to tell me it was teh fuel pump and the cam-shaft positioning sensor.  Paid for teh fuel pump replacement and it died 6 blocks from the dealership.  Then they replaced the RPM snesor, works great now... Except it's still an Audi.

Really need the codes when the light comes on. Stop by advanced auto parts and have them read it, or buy a $50 tool. Will save you hundreds with an Audi.
Most likely is MAF sensor. Not as scary as sounds, and you may be able to fix it your self if you can twist a screwdriver.
Are you getting any coolant warnings?
