I think you will find that is a form of fast idle for when cold, I think it either affects the advance of the timing or helps in another way from cold.
It in no way will be anything to do with immobiliser side.
If you take a photo of the end of your injector pump where the four pipes come out we may be able to advise better.

Mark,
I think that what you are looking at is the thermal injection advance release, that I reffered to in my previous post on your other thread. On cold starting injection is advanced slightly by pulling a knob. This improves starting by giving the fuel spray slightly longer to warm up and ignite.
For detailed info explore previous link, and for a general explanation see here. I think that the flame starter mentioned in the linked page does not apply to your engine which I expect will have glowplugs.
