SR - many thanks for the recommendation. I dont live far away from AutoLusso and was going to go there ref another issue, which, can I run by you quickly:
Car feels to "lurches forward" under light throttle (under 2000 rpm) at the same time turbo gauge drops down then climbs back up again. Other times (when car pulls away without lurching, the turbo gauge climbs steadily as per normal.
Took the car to main dealer: turbo valve replaced, cross over valve reported sticking and cleaned, recon EGR valve (with upgarded seals) fitted and software update installed.
Car doe not always "lurch" when setting off. When accelerating hard, car does not lurch at all!
Also, noticed car has had a couple of "misses" were the engine appears to lose power then rights itself. This was on a cold start going to the shop (admittedly, I was trying to push the car when it was still cold.
Finally, under steady throttle (ie maintaining a constant speed) usually under 2000 rpm, car feel its running rough.
Ive kept this very simple and basic.
Any ideas what it could be?
