    It sounds like the EGR valve is stuck open....this allows exhaust gas back into the engine to be burnt again - and its a plague on most diesels.
    Easy to get to on this engine, anyway!

    Thanks for the quick reply, I've ordered a blanking plate to test this. Would you recommend I drill a hole in it to stop the light coming up on the dash?

    Not yet, lets just see what it does! Another idea - if it isn't the EGR - is to run the car with the exhaust off before looking at the MAF sensor or the turbo.
    Yours has the sort of mileage where the EGR needs attention though.

    Blanking plate fitted & the problem still exists. Since fitting there is much more white smoke coming from the exhaust on start up. The hesitation does seem to be gone/less but still low on power.

    Check in the turbo pipes for lots of oil, will you?

    There is oil in the turbo pipes. What would you call lots?
    Cheers for the advice.

    There's always a bit of oil in there, but not so much as it drips out.....its the smoke issue that spooks me.
    Can you disconnect the pipes to the intercooler just to see whats in there?

    Which pipes exactly? The one to the right of the turbo? Or behind the front bumper?

    The ones directly into the intercooler behind the bumper if you can get to them......just to see how much oil has collected there.
    Back to the turbo.....can you pop the pipe off and spin the vanes? They should spin fine. Also look for any pipes missing from the turbo actuator, on the side.
    After this, I think you need to get the fuel pump pressure checked at the common rail, and then the turbo boost pressure. Has the car had new fuel and air filters recently?
    John :)

    Yes, I did a service last week to try and correct the problem. Ok will try in the morning.
    I've spun the vanes but needed a screwdriver as they were quite stiff. A little oil in the pipe that came off that.

    They should spin freely with a finger mate......not like a kids windmill, but with minimal resistance. Look carefully for any scratching where the vanes may have been touching the turbo body.

    Needed a screw driver to free them up, once I did there were still some very hard spots. The photo seems pretty conclusive too.
    I guess it's a new turbo then.

    Wasn't able to get the pipe off the intercooler. Still wondering about all the smoke.
