Sorry to post this here, tried uk.rec.cars.maintenance but not much in the
way of replies.

I have an 03 reg diesel Kangoo van, 57,000 mile on the clock. On the door
panel its described as 1.7DCi, the plastic cowling over the engine reads
1.5
DCi and the logbook reads 1465cc.

Passed MOT in January which included an emissions test, but now its
started smoking. No change in performance, no starting problems, no sign
of overheating. The smoke is greyish.

How much it smokes varies. It clears when the engine oil level is low,
when topped up it starts again.

Mileage is only around 8,000 pa most of which is stop start traffic,
rarely gets a decent run.

Tried Wynns Smoke treatment in the oil & a Redex product in the fuel, they
don't seem to make much difference. Stopped using Morrissons diesel &
switched to Esso.

Any ideas on what this could be? Someone suggested a blocked oil way or
something - sorry my knowledge of engines, especially diesels is almost
zero.

Without looking at the vehicle, the symptoms sound that of a partially
blocked PCV system where oil is either being forced through less than
optimal turbo seals into the inlet, or through the PCV into the inlet, and
being burnt to create the smoke. You do say it is loosing oil.

I would have it checked out before the engine injests too much, and revs
itself to distruction. Note that failed turbo's on Renaults is umm , par for
the course shall we say!!!
