Ok, here we go agian....,

Fixed the steering shaft module issue first (car totally dead). Then the MMI (2x times, different things), and now this........

Last weekend I replaced the 6x glow plugs. Took it out yesterday for a run. Worked beautifully, until the motor suddenly stopped... It is cranking, but does not start.
I got towed home and run the VCDS, below. I get some faults due to low battery - but that is quite normal after all cranking....:p

Any ideas...? This evening I will check if there is any voltage coming out to the glow plugs. The 80A fuse is fine. Anyone know how to test the glow plug relay (636)?

THANKS!!

Are you getting fuel into the combustion chamber? Does the lift pump in the fuel tank get power and run? Clogged filter?
What kind of compression does the engine have? 28 BAR or better?
How cold it is? Fuel gel?

Not, sure - will check that too. Thanks

I went ut to measure the voltage coming out from one of the ignition wires.... Connected the multi meter to one of the ignition wires and the other to earth. Turned the ignition on without cranking - result - 2.1 V for a few seconds and then 0 V. I guess this is the problem. The 80A fuse is ok, so I´m leaning towards the glow plug relay. Does anyone now how to test/measure this relay?

The procedure is in the repair manual.........

Spray some flammable starting fluid in the intake and give a try.
Do not crank too much or you will potentially flood the cylinders with diesel fuel from excessive cranking cold.

Suddenly stopping bothers me and I would immediately verify basics like Jef advised for compression and fuel delivery.

Went out again. This time unscrewing the glow plug. Turned ignition on placed glow plug on earth - got glow sure enough (for a few seconds), so I guess the relay is ok after all. I will start looking into the fuel delivery system tomorrow.

Is it safe using starting fluid on an engine like this?

Also, compression issue - I´m not that good on diesel engines, but if I got a bad compression on one cylinder does that mean engine won´t run at all?

You need to brush up on some RTFB sir.

You need to know basics before you can test them.

Spraying a very small amount will not hurt it and it should at least try to start ........if it doesn't I'd be having a look at timing conditions for pump.

Please immediately log for RPM ref of G28 when cranking and verify TV or intake flap is opening.
