Evening all,
Looking for some advice, i have an issue with my 2009 TFSi 211
Recently it seems to have developed a rough/lumpy idle and seems to be idling at around 750RPM, am sure it used to idle at around the 800 mark.
If moving off in first gear with very little throttle input the car shakes violently, or if in second gear in slow moving traffic this sometimes happens, enough to bring on the EPC light for a second, also if you plant the throttle at low RPM the car seems sluggish at first and then suddenly springs to life.
Have checked miss fire count and its across all cylinders, only codes i could see to start with were :
Bank 1 system too rich at idle
This seems to have gone and not reappeared and now i get the occasional code :
camshaft position sensor (implausible)
I have changed the spark plugs, swapped around coil packs, checked the hpfp, replaced the diverter valve etc and the pcv valve was replaced last year before this started as the old one failed
If i have the heater/fan on in the car the idle picks up to nearer 800 rpm and the idle feels smoother, and apart from the above mentioned the car drives fine
Just wondering if anyone has experienced this problem before or what to check next?
Any help would be greatly appreciated
