Hi people,
Just like to say a quick hello to everyone first, although not new to the forum but this is my first post.
Afraid to say my W211 E220 07plate has suffered from the black death disease. I have had injector 1 replaced and few thousand miles ago. She has done nearly 300k now . After doing a 200 mile journey over the weekend perfectly fine, the next morning she started up to heavy knocking noise and white thick smoke. I made the assumption one or more off the injectors had gone due too the severity of the knocking noise and smoke. If it did not knock so I would have gone down the road of a blown turbo. Injector 1 and 2 seemed like the likely culprits this time. I decided not the cheap route but get all the injectors checked by a diesel injector specialist whom confirmed injector 1 and 2 where gone and advised 3 and 4 should be done also as they weren't too great either. Injector 3 seemed an original Delphi one to me as the bolt was an original long bolt still.
So I have replaced all 4 injectors now with refurnished one, not cheaply. The knocking noise has disappeared now completely and the even seems to sound idling quieter than before but she is still suffering from thick white smoke. I have allowed it to run idle to see if it clears away with no avail.
But to the turbo, maybe ? After taking the car down it seemed like the smoke had reduced by about 40% and remained to smoke under acceleration. Doesn't seem to be a lack off power nor does the smoke really smell like oil smoke more diesel.
I've scan her and she only comes up with code P0670 and P2030. No other faults showing.
Any advice in what direction I should be heading or at least looking towards for now.
Much appreciated guys, thanks in advance
