Guys bear with me! my next job would be to replace injectors as car smokes under hard acceleration, found however this solution below in another forum for smoking diesel so probably not yet until problem gets worse and someone nails it on the head rather than guess!!
Can this be true for my e220 cdi 56 plate auto?
"Re: Black smoke on hard acceleration
a loose hose clip on the pipe allowing in too much air on the wrong side of the MAFsensor." I guess this would cause a rich mixture and smoke. Problem is smoke, black or grey and one time white cloud and lingering for 500m! At neutral car smokes a little when pressing petal but no smoke at start up in morning or at pull off when cold. Also prone to smoking after town idling when pulling off at traffic lights, and this sometimes... When it does it also feels sluggish and underpowered with no engine extension for the pressure of my foot on the petal.
Already my injectors diagnosed at their limit by indie inj. specialist. One of them way over ...meaning adj value at 5 if memory serves me right? Possible? No visible sign of leaks in engine. no other engine problems apart from occasional slight misfire at idle. No codes whatsoever, mb dealers say. Car already serviced at mb a few times. Miles: 120k.
My oil also smells of diesel as well and is pitch black immediately after change.
Is the injector leakage a likely cause for smoke? Or do the symptoms above indicate something else? Worn pistons, rings, egr (checked) Anyway if i change the injectors would this make the solution much easier with a bit of luck?
Thanks!
