I've done lots of searching on the forum for problems with the V6 3.0CDTI engine and the engine judderring/shuddering at 1500 revs in 4th, 5th & 6th gears, as I'm having this problem with my engine.
I have a 08 reg facelift (z30??) and all the threads talk about a pre-facelift (y30??) engine having this and possible probs with the SCV valves???
Can this still be the issue with the facelifts and the Z engine???
Cars been into dealer to have a look at it - and he says no fault found.....
Any help would be appreaciated before I go back to them..
