1.9TDI smoking under acceleration???
Afternoon, have a slight problem....well to be honest i dont know if it is or not.
I have a 96 B5 1.9TDI 110, its doen 130k now has had two turbos in its life the last one within 7-8k miles.
My problem is that when i accelerate it chuffs out black smoke, not blue oily smoke, just sooty black stuff. The harder you accelerate the worse it does it, normal cruising or on tickover there is nothing visible form the exhaust, just under heavy acceleration.
Why is it doing this? There seems to be no loss of power, it pulls very well, still does a gazillion miles to the gallon etc. Another thing is that i have an MOT to gte through in the middle of May, will it fail on emissions or anything because of this or do they just test it on tickover??
Any help will be appreciated.
Thanks in advance.
