Black smoke?
Budgie:
That would make sence, N reg onwards then. :?
Xtremeteam:
AFAIK the "cat" on a 300tdi isnt actually a cat,its just a particle collector which catchs the larger particles of soot,seen a few now that have started smoking really bad & its been that that has been choked solid,fit a new down pipe without the collector & the motor goes fine again

My 1998 TDi has just gone through it's 2nd MOT without problem and without a CAT fitted. Emissions were fine too.
The exhaust on my Disco is made up of a Defender down pipe (no flexible hose to rot), and no CAT. It costs about £130 front to back, fitted!
Bulli:
Often oil in the turbo , a little normally get past the seal when its been stood. The reason why the turbo doesn' repond to the increase in fueling is that it isn' exhaust gas that makes it spin. THe turbo spins as a result of heat,thats why it lags more when the engine is clock cold.
