im getting bored of this...
So the problem is still there.
It drove fine on my 15 min test drive after changing the sparks. It drove fine on a 40 min drive at varying speeds on the m11.
The driving back tonight i stuck the cruise on 80 and drove for about 35 mins and then dropped in speed and when i put my foot down again (in 6th in manual) it started doing the hesitation and lumpy running.
Each time its done it.. its been after a decent run at around 80mph .. a couple of times on cruise and once just keeping a steady speed with the throttle. Thats the only similarity I can think of.
I tried to take a video but it doesnt show how 'lumpy' it feels.
What you can see is it sort of surge a bit when i put my foot down and then the revs drop a bit and then slowly continue to raise... but as they are slowly raising it feels very hesitant and lumpy. Its hard to see.
I had it in manual mode on the dsg
