Been having problems with warm start for about 2 months, gradually got worse. I changed the fuel filter and cleaned the throttle (which was black on engine side). In the end the car would not warm-start for over an hour. Finally it would conk-out whilst running after about 1 min. RAC came in the end and their computer said the crankshaft sensor needed replacing (all else clear). Got this done by the local garage (non-Audi part) as it was a bitch to get the rubber boot off and into the sensor space on the FSI. After the replacement the problem was not resolved (but garage said no other faults on their computer). Car only started for 30 seconds and then stalled. Now the engine turns but doesn't fire at all. Garage thinks probably an electrical or sensor problem.
I have spent hours on this EXCELLENT forum looking for a similar problem by other owners but to no avail.
Please help me......
