I've an 04 A3 2.0 tdi not starting properly.
The car is with an audi dealer and they dont know what the problem is.

They have changed the ignition switch, wiring looms, heating plugs, control units and now they want to change the ecu and hope that sorts the problem out obviously all at my expense.

They're only guessing at what the problem could be and i'm just wandering if anyone has come across a similar problem or has an idea of anyway to fix the problem.

Thanks
