    Default Cold Start - White Smoke - Juddery Engine....?

    Hi all

    Not been on here a while as the car has been running like a dream so haven't had to call on any advise...but nothing is perfect lol

    Had the glow plug light on for a while now finally changed the faulty one...but ive noticed when starting the car from cold it starts fine but i get a cloud of smoke (white.grey) for a little while until i blast the accelerator? Also the engine is juddering until the accelerator is pressed?

    Any ideas?

    The car starts fine and runs perfect....also changed all the filters 2 weeks ago.

    Any advice?

    Oh its a 2.0 DTi Signum.....110k 2004.

    You've changed the wrong glow plug (or more than one has failed). the white smoke is unburt diesel. The unheated cylinder will catch up and fire and that is when the smoke clears.

    The juddering is running on 3 cylinders, 4th one catches up as you throttle on.
