could it be injector problem

its a200 tdi defender engine that starts fine with usual puff of black smoke. runs a bit rough when cold , and also when idling though this may be helped if i could find out how to turn the tick over up,its when I'm trundeling about it starts sending out white smoke but as soon as it gets a bit more throttle it clears away and is other wise fine on normal town driving. could it be a faulty injector not spraying proparly at a certian preasure but some how spraying better at higher preasure when more feul is pumped in . any thoughts cheers. its running on 30% veg oil 70% diesil

Is the white smoke only when cold, or at all times when you trundel?

there is a bit when it starts but not all the timr but is there hot or cold when I'm just turndeling about jist when you back off the throttle and let the engine do its own thing but once you put the power back on it clears again fairly quickly. jist does seem to do it if your normal road driving.

I'm in Lanarkshire.
Pop in some time and we can hoick out the injectors and check them for pressures and patterns.

Easy job as long as the injectors aren't stuck in the head.

Before you do, make sure you can lift the injectors and that you have some spare sealing copper washers.

What engine is it? We need to know the setting pressures,
