Could be a boost pipe that has popped off. What car do you have? The lower boost pipes on the 130's & 150's pop off at will. Have a look around the engine, and underneath where the radiator and intercooler is to see if there is anything out of the ordinary. Black smoke it normally a sign of a boost leak.

its the 110. ive had a look but the all look ok the is a hiss but there is a slite hole in the flexy on the cat pipe.

If there was a turbo pipe off there would be a significant loss of power. Engine management light on. And probably going into limp home.

Take it to a garage so they can plug in a diagnostic machine to check for fault codes. Then go from there.

Could be something simple, could be the turbo on its way out.. 

Hope this helps.
