I have a 2005 1.9 diesel Laguna with 74000 miles on the clock. Under gentle or heavy excelleration I get quite a lot of white/grey smoke from the exhaust. The engine is really smoth, ticks over well, pulls/accelerates very well. What do you think would be causing the white/grey smoke?

Generally speaking, its a sign of unburnt fuel.

Also lean mixture can produce these colors.
