Had this realy weird thing happend today. I was on my way to work and the car was fairly warm (off the blue on gague ) and as I looked in my rear view mirror I noticed some white smoking coming from back. Instantly stopped the car to investigate and saw nothing untoward. I drove on further and when I stopped at the lights I notices a few wisps of white smoke and then nothing for the next 10 mimutes of the drive. I will see what its like when I go home. All I can describe the smoke as it what you get when you start it up in the morning or from cold. Got myself in a right state reading about Turbos and Manifolds!!!
Its deffo not Turbo pipe as I have one of those go on the Landrover and that chucked out plumes of thick black smoke ! Maybe its crap diesel 
Keep ya fingers crossed for me
Never anthropomorphise computers. They hate that.
if the car had just got warm enough then the white smoke might be occurring in the shutdown sequence. I'm sure we will have lots of threads about the pre-heat system in the next months 
Good luck
. Started car at 7.30pm and no smoke but unusual sound when revved the car there was this sound that was weird. Not the whistle you get with the turbo but almost an low woo sound (I know but I can't think of another explanation). Drove home and saw a little white smoke but just the once and nothing unusual on kick down. I've got myself in a tizzy think cracked manifolds, shagged turbo, knackered breather the lot!!! When I pulled up outside the house turbo sound back to normal. That smell though just ain't right.
