Hi, I have seen quite a few similar issues posted with the 2.0FSI AWA engine. Basically it does not idle very well and it sometimes seems to misfire at about 2000 RPM occasionally. I have plugged in and got the following repeat faults:
16698 - misfire(s) detected single (unspecified) cylinder P0314-001 intermittent
16712 - knock sensor 1 (g61) P0328-001- signal too high - intermittent
17927 - camshaft adjustment; bank 1 P1519-008- malfunction intermittent
The car also sounds quite tappety at tick over. One mechanic suggested that the tappets may be starved of oil because of a blocked oil pick up in the sump. The car does not display any oil pressure warnings though.
i have used the car to drive a 300 mile round trip this weekend and when cruising along the motorway it feels perfect and returned a health 37mpg.
Any help would be greatly appreciated!!
