Black smoke is an indication of too much fuel being delivered and the engine is essentially "flloding" itself.
Most likely a mass air flow sensor or throttle body issue. Try cleaning the body first.
ps
White smoke is a head gasket
Blue smoke is piston rings.
You have the cheapest smoke issue to fix.

Black smoke from exhaust means engine getting to much gas.
SOURCE: Black smoke coming out of exhaust, only on
Your engine is running "too rich" meaning more gas is going into the chamber than is supposed to. If it is a late model, to need to see your mechanic. FYI , blue smoke is oil, black too much gas, white, antifreeze, (really bad).

This is almost certainly a split hose - mine was the large hose coming out of the bottom of the EGR valve.
Speaking to a parts guy at my local Jaguar dealer, he said that the new part is uprated as Jaguar are aware that this is a problem.
The split allows more air in and results in the ECU changing the mixture and over fuelling - Black smoke is an indication of un-burnt Diesel. As well as the black smoke you may also notice a whistle/whine or sucking noise when you accelerate and a lack of power / lumpiness at around 2000rpm.
Hope that helps!
