Hi has anyone had the following, when switching on the ignition the engine management light does not come on and hence the engine wont start! I have to wait anything from 10 seconds to 10 mins for the light to come on, the engine then starts and is fine, this fault is intermittent. The car has been to the main dealer twice but has never occured there! a master technician had the car for two days with no joy and Audi can not shed any light on it and diagnostics, the fault is still there an dwas wondering if anyone can shed anylight on it.. The car is a A4 Avant 1.9 TDI on a 53 plate..
