The diesel engine under the bonnet. Most diesels smoke when you start them, especially older ones.

If it's not starting easily in this cold, then you might have a glowplug or two out, that will make it smoke more on start.

black smoke in a diesel is over fueling normally.

see minicabs pulling away

Thank you all.

Black smoke is as Dtooth said,  you can see it on on new diesel cars when they put their foot down,  white smoke is un burnt fuel, you may have a dodgy injector, thats dripping into one of the cylinders when it's stood.............

black smoke is unburnt diesel white smoke is too much air in the system i.e air leak in the air intake. blue smoke is burnt oil. i was always concerned about exhaust smoke when i had my diesel untill i saw modern diesels and what they kick out, then i wasn't bothered at all
