Thanks for that encouraging info Martin.
I've been trying to start the car quite a few times to make sure things aren't just random.
So, here's a bit more information.
When I turn the key one of two things happen;
1) The Glow Coils icon shows and I hear the "slurping noise" from under the car as the engine gets glowed and primed with diesel. Followed by the "OK" sign.
2) There's just the dots in the screen for quite a long time, and no noise from under the car, and if this happens it goes straight into the EKG-Error-Icon with the nasty beep.
(In both 1) and 2) the red immobiliser light goes out)
If 2) happens there's no point in turning the key. I can keep on flicking the key until 1) happens, I can hear it early as the car is either silent or I hear the "slurp" noise.
When 1) happens I can turn the key and the car, first time, wants to start, and I think that if I give it a bit of throttle it'll purr up as it should. However, it has stalled several times just after it's fired up.
If it doesn't start at the first few revolutions, it won't start. No matter how long I keep it cranking or what position I have the throttle at (no, a bit or floored.. doesn't matter).
I can keep trying to crank it for a good while, but it just won't fire up.
I have then notice that if I leave the car for a short while (less than a minute) I can go back to it and if I get the "slurp", coil and OK light, then I crank it over and it fires up immediately like nothing was wrong.
I've then, once started, had it running for a while, giving it throttle once in a while, without any problem. It idles just fine, no hunting, no problem. It picks up the rpms as usual, it doesn't smoke. Everything is normal.
Except; earlier today it stalled after about 5 minutes of running with the red engine symbol with 'Stop" written in it. It started up immediately after...
I'm sensing that this might not only be the glow plugs, but maybe something to do with the fuelling...?! High pressure pump, low pressure pump..?!
Anyone got a clue?
