I have an issue which has got right on my wick! it is an idle hunt/flutter its not just the needle it is the engine... it happens just after crank finish of engine, initially for a moment the engine is smooth then it go nuts!
It has been suggested to me an idle increase at startup may help..
I've DIY done:-
Full set of injectors, MAF, Throttle body, Battery, full service...
EGR inlet into charge air decoked, EGR valve/cooling flap been vacuum tested/MVB 03 done(visual/decoke soon to be done)...
I've had done:-
Full set of chains & tensioners, Tiptronic oil change, Last rev of engine ECU software done...
Soon to be done is Ins.cluster flash to last rev of SW as TPI/TSB suggest bad comms between engine & ins.cluster with SW I currently have (should also give me digi.speedo in DIS
) ...
Sorry OP for hi-jack
... I have no fault codes to go by
... fuel pressure/rail/pump MVB look good as well...
