There was a recall on the glow plug relays on some of these,
Yes I read about that.

Glow plugs are located at the back of the engine, there will be a large relay located in the bay somewhere, it will be easier to test them from here rather than trying to get to the plugs, a diagnostic test will tell you if a glow plug is down.
The plugs are not used to start the car believe it or no they are they to get the exhaust temps up to do a particle filter regen etc.
The rough running on start up will be air in the fuel lines, the air filter bobbins break and the vibrations on the filter box put a small hole in the diesel pipes located underneath and cause this issue, the pipe work is about £120 to buy.
Any questions ask away, I see these engines in various cars everyday. Also if you do go to change the glow plugs be careful as they snap and once that's happened it's a head off job.

Thank you Carl.
I've been doing a fair bit of reading around on forums etc. and have never seen the diesel pipes issue mentioned anywhere. Is it really necessary to buy the pipework or can a section of this be replaced? I take it that I'd then have to prime the fuel system to get it started again?
Are we talking pinholes that'd be very difficult to spot or could I see it if I took the airbox off and had a peek over the weekend?
The rough running feels like running on 3 and as soon as there's some heat in it it goes away. Also, it doesn't occur if revved, it is just rough idle with smelly white smoke out the exhaust.
A cheap code reader didn't show up a glowplug fault.
Finally, did you still want to sell that bottle of plasticare you had?
Thanks for your help so far, really appreciate it.
