Smoke from diesels?
Discussion
Generally speaking you can't over fuel a diesel, the extra diesel that there isn't enough air to burn just gets blown out the exhaust without losing engine power so people just pump in way too much when they 'tune' them. On normal cars you get the odd puff on acceleration as there will be a small transition point when the turbo is spooling up that there is too much fuel for the air.

Work out if it has a DPF, if it doesn't then you can get impressive black smoke when you boot it, more so if you've been driving like an old fart for a few days, but a DPF equipped car shouldn't.
Impressive? Do you not mean "embarrassing"? Diesels blowing smoke like soot stacks is not unusual, this is why diesel exhausts point down towards the ground where they would normally sit parallel to the road on petrol versions, as shooting the soot downwards disguises it against the dark surface of the road.
And diesels shouldn't smoke at all by the way, unless they are: A) remapped (badly), B) really old technology, or C) not running correctly.
