Mercedes Vito 108cdi - Vito diesel- white smoke - Columbiers

Hi,

Hoping someone can give advice with this- I only have limited knowledge of diesels! Today my Vito van, 2001, 108 cdi model, suddenly starting poring white smoke out the back, huge clouds of it. This is smoke, not steam, smells very smoky too! Van is running rough and went into limp home mode, not revving above 3000.

No engine light on, no codes when scanned with OBD scanner.

Can anyone advise on some tests I can do to work out what the problem is?

I'll post my favorite chart again if that's OK....

I don't think it'll help much, though -- most of the boxes are ticked for 'white smoke'!

I think the rough running is the clue, what you are seeing is unburnt/partially burnt fuel, its down on one cylinder, usually due to low compression but could be an injetor fault. Take it to a diesel specialist rather than the dealer, they usually know what they are doing and will likely be cheaper.
