Try injector cleaner then a good Italian tune. It worked for me!

Italian tune = a good, high RPM scream along a fast road or motorway. Don't
be afraid to floor the throttle and keep the revs quite high. You may have
to repeat the process a couple of times.

ISTR the idea behind it is that Diesels are often driven conservatively due
to their torquey performance, which isn't always a good thing. It results
in the injectors becoming contaminated with gunge which prevents them
closing properly, so thy dribble fuel into the cylinders when they
shouldn't, causing smoking. A good thrash cleans them out, and they say a
conservatively driven Diesel should be given a bit of a thrash every once
in a while to prevent this happening.

I'm not sure if the TDDI has a rev limiter, but by thrash I don't mean
holding it into the red, just give it a good, spirited run and keep the
revs quite high for a while.

Another thing to check is that the air filter is clean.
