About 4 miles from home, eml came on(little icon of an engine block), no differance in running at all, pulled into a lay by, and popped the bonnet, can see nowt amiss. Turned the engine off, waited 10mins then checked stuff again, oil, water all good. Started her up, lamp still on so switched her off and came on here.
Nanocom is at home :vb-groan2:.
What's likely to put that lamp on? Safe to drive home? I'll call recovery otherwise.

Lots of things can put the EML lamp. If it's running OK and is not overheating, I would drive home. I always carry my diagnostics, no use if left at home as you have found out twice recently.
 
I've just ordered a hard case plastic waterproof box off ebay that it should sit in snugly. Much smaller than the box it came in but that had to hold the chunky obd cable and stuff. The cable will be safe in the glove box, can't see anyone nicking that and I should be able to hide the nano somewhere with a smaller box.

So it's check the wiring to injector #4 as a first step. Have you had the inlet manifold off? If so, it's easy to trap the wires when refitting the manifold.
The wires are not trapped BUT I was driving through a severe rain storm last time it was used(last saturday), lots of surface water and spray about, no under tray fitted. Maybe the electrics around that area got a soaking.

Is there any diesel leaking from around the 4th
injectors sensor/plastic part at the top of the injector itself?
 
Don't know yet. Put my back out brushing my teeth last night.
Sounds funny but it's true, muscles gone into spasm, happens every now and then doing things that really shouldn't cause this. Last time I was just squeezing a tea bag out!
Experience tells me I'm stuffed for anything between 1 and 4 days now.
It did all look dry yesterday with a quick look in the lay by but I didn't look really hard at the time.
New number 4 injectors ain't cheap are they! Jeez aloo.

Does Nanocom show live data for #4 injector?
 
According to the nano, there is no 'feed back' from the needle sensor at all, looking at the pics above ^^^
Should the engine still run cos it does, and quite well too. Although idle is not as smooth as it was.

The pics above are the readings with the engine running, nothing from the injector, crank is, I presume, Crank position sensor which is giving a reading. I don't recall exactly but I did blip the throttle and the revs acted like a sticky throttle cable or a missing return spring on a carb, ie- they went too high and stayed there too long before dropping which made me twitch a bit. Nano was plugged in and I was checking other stuff. Might have been checking if the cps reading increased or the throttle position reading changed, can't recall. I did wonder at the time if the injector caused that issue.

Mine still ran with a dead needle lift sensor, I cannot remember if if ran badly. As you say, replacements are expensive. Have you checked to see if the connector is full of water?
Old fashioned Aspirin works best for my back when it plays up.

It will run on defaults taken from the crank sensor. The needle sensor is only used for the actual point of injection and fine-tuning this by advancing or retarding the point of injection using the solenoid in the top of the pump.
 
This is the lamp that's constantly on. I have no lamp that looks like an injector at all during ign on and bulb test. If I should have one (2001) maybe a bulb has blown.
