What colour? Would help determine what could be wrong with it, leaky injectors is usually white smoke, has it had a full service and filters replaced? Have you checked the condition of the egr valve and inlet system?

Sorry guys - black smoke, not white.

I've not checked EGR setup, no. I'm not familiar with the EGR setup on these motors so I don't rightly know what to look for. Any diagrams or pointers?

Black Smoke could indicate issues with the Turbo but if its passing an MOT and mpg is okay, I would ignore it unless you want to throw money at it.
Has it got big mileage ?

Nah it's only on 125k, not a lot really.

I'm tempted to get it on a ramp at weekend and check for boost leaks (i.e. loss of charged air making it go rich) and blank the EGRs off to see if that makes a difference. I must have a bit of cake tin or something somewhere to make a couple of blanks up with; unless they're visibly caked up and not functioning properly in which case I'll clean and restore.

I just don't know if it will throw a metered air or air quality code up; later cars I know certainly will but I don't think cars this early should care - if memory serves it's only about euro 4 on that it got clamped down on.
