1.7cdti jumpy throttle

[chriz1]

Hi all,

I own a combo 1.7 cdti 2006 it's done 126k.
The van drives really well plenty of power. The only thing is when say in stop start traffic 1st or 2nd gear feathering the throttle or changing low gears the van jerks or lurches forward or when coming off throttle almost gives whiplash no matter how gentle I am with the throttle.
Say over 30mph or higher gears the van is fine and I can lift off as hard as I want and it doesn't do this lunging.
Fuel filter is been changed, egr cleaned although can't be fully.cleaned on this engine, boost sensor cleaned. Checked for air leaks, changed fuel brands,

I have live data although looks ok to me but I havent got a trained eye .... unless someone can understand it.

What should I be checking?

Any help guys can't find many cases on the net at all.

Any fault codes showing?

If you have access to the pics, I'd look at the throttle position and maf/map readings to see whether they reflect your throttle inputs.

No fault codes showing.
What values should they be showing I can't find a way to post the .csv file up here
