306 kicks out black smoke when turbo kicks in

hi all, i own a 97 306 5door d-turbo with 80k on the clock. As i have
never owned a diesel before this car i have noticed that when i floor
it in 2nd and 3rd it leaves a nice black cloud behind me when the turbo
kicks in.
But if i go up the revs slow it doesnt do it.
i have heard this is normal, is this true?
or does this mean there's something wrong.
it had a service about 600miles ago.
cheers marc.

 

Its an oil burner so if you rag it you'll see the results in the rear view
mirror. Having said that deisels do benefit from a good thrashing from the
right foot once in a while to clear out the sh1te. Just make sure its
warmed up first.

 

Just make sure that the air filter was changed during the service, it
wouldn't be the first time....
Diesels do build up soot in the exhaust when used on low throttle round
town, or on short journeys. Then when you boot it hard it all comes out of
the back end. Normally once you have cleared it, it runs cleaner the second
time. This is a handy thing to remember at MOT time. Take the car for a run
first, get it warm, then on a suitable road, floor it in second, and keep it
there for about 15 seconds. This cleans all the sh1t out of the system, and
gives a far better chance of a good emissions figure.
If you have an ongoing problem with really black smoke on hard
accelleration, then it is possible to get the pump adjusted to reduce this
affect. If it is done properly then it will not affect performance.

Cheers fellas will try your hints out and i'll have a look over the air
filter!
if i got an induction kit for it would this help or do you think it
would make it worse??

 

Well, induction kits are supposed to make the engine suck air in more
easily, so it might help, but the emphasis is on the "might".
