I think this uses the early DI engine with an injection pump, if so there is a fuel solonoid on the pump which can fail but it may be enclosed for security, if not it should be a relatively easy job to change.

Great, except, remember my username....... dieseldummy.... I know what a fuel solenoid cut off valve is in principal, but, where do I find it and how do I repair it please. Also, are you able to shed any light on the idling too fast issue. It is definitely not related to external cable and "stop" adjustments. I disconnected the cable and after very carefully marking and measuring I let all external adjustments back to "zero" and it still wants to idle at just over 1000rpm??????

Easier said than done. I'd happily spend the money but I can't find one in this country. Any suggestions please.

Now that's helpful, cheers. I'll let you know how I get on.

Further to the above, anyone any ideas about the too fast idle problem I also mentioned?

My ancient tech Berlingo uses a mechanical wax cold start device, and these are notrious for getting stuck on mine, I wonder if the same applies to yours.

Hmmm. I can picture the principle. Any ideas on how its actually implemented?

From memory on mine it's the only other cable on the fuel pump (Apart from the accelrator cable)

I just removed the cable from the pump and left it as is. I starts first time in winter and idles fine. I was going to change the wax 'stat but it's a ball-ache of a job.
