    Hi i've got a C270Cdi 2003. Had it at merc to have the headgasket and HP pump replaced. When i got the car back it was down on power and smoked at start up. When it reaches operating temp no more smoke. Merc sorted the loss of power was due to loss of vacuum on turbo but are baffled by the smoking. I had turboseals done but still smokes.

    Merc did a compresiontest and leakdown test and they say all is ok. All cylinders are 17bar and no leaks on injectors. Even merc in Germany say all tests are within spec. Any sugestions or possible cause.

    Thanks in advance.
