I describe this as Jerkyness coming off the throttle!
Sometimes it will be fine, sometimes it can be pretty violent. I've had it a couple of time in second gear going round a roundabout where you are at the point of just coming off the throttle, you can get a big lurch (jerk).
I think this is happening as you are coming off the throttle and are in the zone between the throttle cable driving the butterfly valve in the throttle body and the ECU driving the valve. Seems that there is a period where it doesn't get set properly.
All temp sensors, dump-valve etc have been checked and replaced, also MAF, sparkies etc.
1. Another thing I'm worried about is could it be the dual mass flywheel on it's way out???
2. Another thing it could be is the turbo actuator getting stuck, does this sound feasible?
I got exactly the same problem - started about 2 months ago, then my idle speed was intermittently high, and my cruise control intermittently working / not working. Vag-com said Throttle position actuator problem - VW confirmed this and replaced the throttle body (luckily under warranty) at a cost of ?440. Strange though, now the idle speed seems ok when engine is warm but when first starting in the mornings it idles for a minute or two at about 1500 to 1600rpm and i still have the stuttering talked about here, i find it most noticeable when i am driving at about 30mph in 3rd gear and very slightly creep on and off the gas to maintain speed. Really annoying problem. Any ideas guys - Vag-com is completely clear of error codes by the way. Should i start replacing temp senders or what [?]
mine is most noticable at partial throttle in seconde gear. Just as the car has accelerated as fast as the partial throttle will allow and the speed levels off with no change in the throttle position, bang... the jerk. I have also noticed that this happens more on the 'ultimate type' superunleaded. this is an intermittant thing too.
