car smoking when cold

[audi660]

My s6 smokes very badly when the car is cold, but once it is nice and warm it stops smoking..
The smoking is much worse in idle.
Can anyone help me with this problem?

Oil??

What oil are you using? It may be too thin. I had the same problem, Changed to a slightly thicker oil now never burn a drop.

This could be caused by poor valve guide seals or the turbo seals are poor.

when you stop the oil drips into the turbo or cylinder head and is burnt off when you start the engine.
