    Have done a seach on my symptons and i'm still a tad unsure.

    I own a 1.8T quattro AVJ engine.

    Today the car started fine, drive round the corner and once waiting at a junction the car stalled and wouldn't start again.

    I left it for about 5 mins then tried again in which it stalled, this time i restarted with a bit of throttle and the car started but with the 'epc' light on and it was idling at 1100-1200rpm.

    Is there an idle control valve on thiese models?

    Anything I should check? Is it worth reseting the ECU (taking the battery of) to try and clear the problems.

    Cheers guys:ermm:

    People have to view your post to see whether they know the answer. I don't know the answer which is why I haven't replied. Sorry!

    It might be the engine speed or camshaft sensor, that causes sudden cutouts, usually works after 10 - 15 minutes when the sensor has cooled, its at the rear of the cam cover as far as I know but the one on the B6 has been fine so not totally sure. I had this trouble with the Golf GTi, and the B5 I had before.

    It may also have been the immobiliser / key signal weak but then it would flash the "car with the key inside" symbol.

    Remember we are all amateurs or engineers in different disciplines, not mechanics, so we can only help if we know the answer, and even that is an educated guess without testing anything or seeing fault code data. You need to get it scanned by a vagcom set or an audi dealer's 1550 machine etc to know what you are dealing with. ECU controlled cars are complex, and fussy.
