The engine seems to drag every now and then, when in low revs the engine jumps and black smoke will come out of the exhaust. Also there is a rushing sound when you accelerate like an air leak. Then after a while engine management light will come on any ideas? (Laguna 1.9 dci 51 reg)

laguna rushing noise !! it sounds like the turbo intercooler has failed if you look through the front grill at the radiators top edge do they run parallell?
if not the intercooler has expanded and split you need to remove your grill,bumper,headlamps&top front panel to gain access you may even need to have the ac emptied and refilled by a dealer???
