There's no problem. [

It is known that these cdi engines, especially if they have a few miles on them, start to smoke. Sometimes little or non, sometimes tonnes of black smoke.
Our 320CDI smokes like hell when I stamped it open after a week of city driving by my mom...[]
It's probably the catalytic converter that's full of crap, and gets blown out when making revs and driving hard.

Mine started to create a lot of smoke too, it turned out to be an injector that gone bad, seems to be a common problem and above that they are really expensive cost me aprox. 640$ labor excluded.
Main reasons of black smoke as far as I know:
- Leaking injector (Most common).
- Malfunction of commonrail pressure sensor.
- Malfunction of commonrail regulator.
- Malfunction of air mass sensor.

Our's had a leaky injector too, and was also replaced.
More reason when excessive smoke can occur:
- Clogging of the inlet manifold, causing too little air getting into the engine in relation to the amount of fuel to be injected.
Further progression of this problem and you get what our car has: Constant limp mode (little power, and rpm limited to 3000rpm), caused by the AMS that gives an unreal value to the ecu, etc, etc, bla bla bla...
- the EGR valve which is bolted on the inlet manifold can get stuck, and the valves inside the manifold too. This will also cause limp mode and excessive smoke.
At the side, these cars are definately not made for short grocery runs. I can feel that the car doesn't like it when my mom drives it 2 miles into town and back. When I get in afterwards, I try to get all the crap out as much as possible... ofcourse in limp mode it's not that easy hehe.
