First thing to do is whip the inlet pipe to the turbo off (couple of clips) and check that you can or can not spin the impellor with your fingers.

Sticky rear brake caliper will do that too , just look at the discs after a run .

check the manifold pressure sensor isn't blocked up

check the hoses after the turbo to inlet could be a hole.
i think tho it would smoke if there was a hole. other thing it could be is a blocked diesel filter they do strange things when they cant supply the fuel

quick update took inlet pipe off and impellor spins freely,checked hoses and pipes couldnt find any leaks ,quick question where abouts is the manifold pressure sensor

If your turbo was not kicking in then you would definatly feel no power what-so-ever. All it serves to do is heavily block both inlet air and exhaust gasses out. The truck will struggle to get anywhere above 30 mph. I would think its something else thats the problem. Check your air filter hasn't gummed up .. or even better for the sake of £10 replace it.

on a euro2 engine it's at the front of the inlet manifold with a pipe going to the manifold itself, on a euro3 engine it's at the back and is fitted straight in to the manifold no pipe.

could be they do block up so just disconnect the exhaust at the joint above the main oil filter and give it a run,
