so iv'e had my A4 for about 3 months now and i love it!!!! i took it for a health check courtesy of Audi and the usual crap returned, replacement screw £140, wiper linkage squeaking £245vyada yada, anyways one of the things found was the G80 injector had an intermittent fault....
there was a slight stutter in the idling which id noticed but only when at stop and when you really tried to feel it as it doesn't show on the rev counter but it is noticeable....
so without further hesitation i plugged her in myself and sure enough G80 intermittent short to plus or open circuit.
bought the injector, £350 worse off replaced it and the code went away... YAY success...
however this did not remove the funky idle!!!! there are no more fault codes after a clean sweep with vag-com but still this random lumpy but hardly noticeable idle lumpyness!!!! and its driving me mad.
anyone had an issue like this before? the car runs fine otherwise.... good mpg around 37 average, smooth motorway running and a dream to drive!
2001 A4 2.5 TDI Quattro AKE with 99K genuine!
cam belt at 80K
Regards to anyone who has any ideas!!!
