Hi wezy

How did you get on with this problem? Sorry to dredge up an old post but my problem seems the same and it's kicking my ass.

Same puling when you come off throttle, more than that, if you dip the clutch it revs up gently for a second before settling to a steady idle. Is that the same?

I've had it pressure tested, smoke tested and various other diagnostic efforts but nothing gives, next recommended step is the lambda, but we think we're grasping. Wondered if you had a wonder fix?

( I know from vagcom the ECU is requesting a rich mix just at these times, but can't figure why )

Thanks
