id check all the pipe work for the turbo but black smoke indicates overfuelling

[tigertye]

what could cause it to over fuel and now you mention it she did say other day that when she parked up that there was a cloud of black smoke at the back. And i was followin her the other day when she went round corners there was what seemed to be droplets from the exhaust cheers for the reply

[marktaylor]

the droplets from the exhaust are usually condensation from when the exhaust heats up

Check air filter is not black or sucked up a cloth or full of leaves, as restricted air flow will cause over fueling ie: Black smoke.
