Hi

My 850 TDI seems to produce the infamous diesel black smoke. It is not really noticeable on normal cruising but under acceleration it is at its worst.

Any ideas of how I can reduce this. Is there anything specific for this engine that would be worth checking?

Thanks

Stu

A noticeable white smoke suddenly appeared on my exhaust one day, and set the Lambda light on. Refer to post on 'Lambda Light'. I sent it back to the dealer right away.

WATER (?) in fuel mix...?
That can't be good, can it?


I don't know, Barmy.

Correct.

But the Volvo 850 TDI does produce a nice black cloud as well when stepping on the gaspedal... nothing to really worry about! When disconnecting the EGR-valve, it slightly reduces, but don't expect miracles then!
