Its a R plate S40 TD with 156000 on the clock. Whenever the engine is\nstarted from cold there is plumes of blue smoke from the exhaust and\nit is prone to stalling when stopping the car until the engine is\nwarm. Even when driving if the revs drop below 2000 rpm their is a\nlack of power when the throttle is pressed and more blue smoke out of\nthe exhaust. The only way to stop it is to bring in the turbo. A\ncoupe of friends have told me it is a fuelling issue so i changed the\nfuel filter but it made no difference. On occasions when driving when\nthe engine is cold it is very hard to get the turbo to kick in at\nall!! ADVICE NEEDED PLEASE!!
