I'm having bother with mine just now too and it's starting to sound like injectors reading this thread.

There are no split intercooler hoses and i've had the EGR and inlet off and cleaned them both out.

Lots of blueish smoke on start when cold but seems to clear when it's warm,won't rev over 3k and absolutely no power at all,turbo doesn't seem to be kicking in.

When it happened first it made a whooshing noise like a hose bursting but i've checked them all again and again and can't see anything wrong.

Gallon of petrol and a match making their way towards my car soon!
