A class (169 diesel)

[ilunn]

Ok Fingers, toes, legs in fact everything crossed that transmission (CVT) now fixed (I'm quick at striping it having done 3 times in 3 week) any way one of next things I need to address just because I cannot resist getting things as close to 100% as possible is the slight lumpiness from engine at low speeds, There is no codes being generated so thinking possible, things like EGR blocked, splits in hoses, ect one thing I have noticed it does not idle consistent and the rev counter can fluctuate maybe 25 to 30 rev's at idle.
Any one got any suggestions as to common things on these engines? I's done 106000 mile. Can Egr be blanked or does it then come up with fault?.
