No it's not a coming out of the closet whilst setting up a business moment, I am getting a puff of blue smoke on start up, it's really not enough to concern me, as its not really what I would call excessive, but I do like to know whats behind stuff.
Its not really bad as I have only noticed it when waving to wife (with kids, as id look pretty daft waving her off on my own) when she goes out (point being I am in line with exhausts when she starts it).
I did have a petrol car years ago which needed valve stem seals to cure it, but obviously this is a diesel turbo so wondering if its the same or a sign of turbo trouble or indeed engine wear.
Car has been over serviced, so as long as it hasn't been thrashed cold we should be ok there. 2006 3.0d 76k.
There's no blue smoke when driving, just start up.
It's the best car I have had, so please no bad news lol!

No help to you but, took me a second then LOL!

The engine management system over fuels the car to assist in cold starting, that's why you don't have to wait for it to pre heat, it is noticeable when the car is first started, especially on cold mornings. You won't see it when the car is warm. They all do it its normal

Unintentionally I only ever watch it when cold so just assumed it always did it, thanks for the swift (and non worrying) answer.

Mine does iit as well.
