Diesels do that, at night with a car following you, you'll probably
think a fog has descended!  It really shows up under those
circumstances.  You can see it happening when people overtake in a
diesel, I've driven a fair few diesels, not yours, but they all smoke
a bit when you accelerate hard.

Of course if you're spurting out thick white or black smoke that fills
the road and forces other drivers to stop, then that's another matter ;-)

This is normal

Why are you accelerating at 4krpm in a diesel when the power has tailed off?
