Hi. Have a problem with a e220 cdi (210) model 70,ooomiles. Starts ok, but then idle speed tends to dip quite lowfor a few seconds.If you attemot to select reverse or drive it may stall. If you rev the engine all seems fine untill around 2500rpm. Then it seems to miss fire and smoke from exhaust Grey/blue ish in colour but smells diesely. Have replaced mass air sensor, changed fuel filter, run from lifeline (fuel can) disconnected front cat from turbo, disconnected egr valve. No different. No fault codes. Any ideas. If you drive car gently nothing really appears untoward. Many thanks in advance of any ideas ???
