Hi to all. Please can anyone offer assistance? First visit here - caused by problem with my 2002 A4 1.9TDI 130BHP. I have had repeated electrical warning lights coming on from time to time, but recently my ESP light comes on (and stays on until I switch the engine off) when going round a roundabout. Is it safe to drive with ESP off, even though its summer? Maidstone Audi want £105 + vat to diagnose, does this sound reasonable? Any quick/cheap fixes? Its my first Audi, so Im not sure of servicing costs etc. Only got 66k miles on and Im a bit disappointed that I get these problems. All help much appreciated.
