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?
