Hi all. Ive got an AUDI A3 2.0TDI SPORT, and for the past few months I have had trouble starting up the car in the morning. After putting the key in the ignition and waiting for the lights to go off i start the car up. And I get nothing. I turn the key back and try again and then all of a sudden its about to start and it dies and then whilst the key is turned still it finally starts up. The car shakes for a few seconds and then it is normal. The issue only occurs in the mornings first thing. Once the car fires up I have no issues with it during the day. Some mornings I have no issues with the car starting up, its starts up fine. And some mornings I have this problem.
So I took the car to a local garage and had it put on a diagnostic. the diagnostic came back with fault code-
"P0673 CYLINDER 3 GLOW PLUG CIRCUIT -Q12:ELECTRICAL FAULT". The mechanic had no solution into fixing this issue as it could be various problems. A bottomless pit. So earlier today I had the same problem with the car starting up. Wouldnt start on the first try, after the third try it fired up. So I took it to a diesel specialist. Again had the car was put on a Bosch Diagnostic and it came back with "FAULT 269 GLOW PLUG CYLINDER 3 OVER TEMPERATURE". The mechanic had said to me its an ECU fault as the ECU is sending out wrong information out to the car. As far as I've been told any ECU problems can only be dealt by from main AUDI dealers. As they can only program the ECU. And could cost approximatly £1800 to replace.
Before I take the matter any further I was wondering if anyone on here has had a similar issue to what I have and what procedure was undertaken to resolve this issue.
Any Audi specialist technicians or electrical technicians, your advice would be very much appreciated
