Our 20 month old A2 has developed a fault with the Hazard Warning system which Audi can't rectify. They have replaced two ECU's, one for the Air Bag system plus another one, but still the warning lights keep coming on for no logical reason. Any one got any good ideas ?
Pulling the fuse stops the problem, but what is causing it. It could be as simple as a faulty switch but that would be too easy.
