Hi all, i have a 2006 is 220d. It seems quite sluggish. When i stop at the lights or sit stationary it sounds like a tank and the rev needle jumps from around 800 to upto 1200 revs and straight back down, and the car judders feeling like a rollercoaster when sat stationary. If i put the a/c on this seems to stabilise but not totally remedy it with only slight rev alternation. I have the egr thing cleaned several times and on all occassions it was badly choked is there some underlying issue
regards
Mike
