Hi all, first post on here so please go gentle.
Had my 3.2 8P for five years now, been pretty much faultless up until before Christmas, it started as a couple of stalls and rough idling at traffic lights, which would restart but die pretty much immediately, both the ABS and engine check lights came on , after leaving it for an hour, it restarted and all was fine, engine management and ABS lights went out after a day or so . I didn't have any version of VCDS at the time and as it seemed like a glitch which had now disappeared i left it, the car then performed perfectly throughout all the recent snow and crap weather. Then yesterday on a busy 'A' road my gremlin reappeared, exactly the same, would die at low revs and was difficult to hold at idle and then select drive (not easy in a DSG), engine management lights and ABS lights all back on, tried a dozen times and it continued to do the same, eventually got to a safe spot and left it to cool down for an hour or so, tried again and all was perfectly normal, drove the 25 mile trip home and it ran perfectly.
So today i dug out an old VAG-Com cable and managed to get it working with the downloaded version of VCDS-lite, here are my findings:-
6 Faults Found:
18025 - Glow Plug Pre-Heat Indicator (K29) : Open or short to Ground
P1617 - 001 Upper Limit Exceeded - Intermittent
18104 - Power train Data Bus
P1696 -002 Implausible Message from Steering Column Controller - Intermittent
17499 - Mixture Regulation; Bank 2; Range 1
P1091 - 002 - Rich Limit Exceeded
16486 - Mass Air Flow Sensor (G70)
P0102 - 002 - Signal too Low - MIL ON
17573 - Long Term Fuel Trim Additive Air; Bank 1; Range 1
P1165 - 002 - System too Rich
17550 - Load Calculation Cross Check
P1142 - 002 - Lower Limit Exceeded - Intermittent
Readiness:0000 0000
So i know that the first error of 18025 is rubbish and has happened to a few other 3.2 owners (weird but no idea why), the others though are a mystery to me. I saved the codes and cleared them, also took the car for a spin with VCDS connected and no further errors appeared.
My wife uses the car a lot and it's just been lucky that on both occasions this has happened it was me driving as it's a bit scary when it does.
Any ideas...?
