Continuous trouble with black smoke

Blue dragon said:

Hi I am new to forum chat groups but feel confident this group can help us solve our TD 4 problem! We have been back and forth to garage few times asking them to find out why there is black smoke coming out our freelander. We did a full set of filter replacements and oil change plus checked and replaced two inter cooler hoses. They also cleaned out a smaller filter recently which I cannot remember name of. It was clean for a day or two but has sadly returned again. The car is a 2003 Freelander TD4 is this just an age thing that we are stuck with or is there something else we could try?

Black smoke is over fueling, or a lack of air. So you need to check that the EGR valve is clean, free to close and not sticking.
All the boost pipes (there are 4 on a 2003 TD4) also need to be checked for leakage.
It could also be suffering from carbon build up in the inlet manifold and intake ports. This causes cylinders 1 and 2 to get less air than 3 and 4, giving rise to black smoke under acceleration.

Do you know if the garage checked the fuel system? I've always thought black smoke was the result of over-fueling.
