smokey

hey all
my 335d had recently started smoking from its exhaust after being sat idling for few minutes, no smoke at start or driving along though, it seemed to be a whiteish color, however i thought id try get a vid today to show you but it didnt smoke once, even filled with v power and the fume smell has lessed alot. is it something i should be worried about? iv got car in for mot on monday and due a service, i did ask them to have a look but im concerned if it didnt happen today after a run then it may not happen when they have a look.

Do you regularly change your engine oil?

Whitesh in color is typically just water vapor, normal for all engines. Was it a bit cooler today than it's been in a while? This will make the water vapor more visible. Also with a diesel, the oil will get very black in just a few miles after it has been changed. Completely normal.

no the weather has been quite warm today, though some days it was cooler. but it wasnt a small amount of smoke, it was plainly visable and seem to give a bigger puff as u pull off but then gone as your driving.
