Its that time of year again you might know its R4 the glowplug relay but I found it from the diagram on the fb lid.
Next question do you know what the resistance of all the glowplugs in parallel should be? I am getting about 1.9 Ohms which would give me a current of about 6 Amps for all the glowplugs (that sounds a bit weedy)
Also fuse F4 feeds it and cant see it in the fuse box? Just a black plastic cover.

The resistance of the glow plugs is generally below the accurate measurement of a DMM, requiring a specialist kind of resistance meter. It's generally better to measurement the current, but again you'd need a current shunt to measure the high current needed for the glow plugs. Each plug is about 1ohm, so will pull over 10 Amps.

Is there a separate glow plug controller? I'm sure I've seen something in the manual about it.

The glow plug controller is on later models I think (post 2010)
I think you are right about measuring the current, I have an idea that I will post on here when I try it.
I bypassed the relay with my DMM (in current mode) and it read 14A initially dropping to about 6A after 6 seconds so looks like 1 or at best 2 of them are working.
It is booked into the garage for a new set of glow plugs next week. Disappointing as it had a set fitted at a Land Rover dealer only a couple of years back. I have read that Delphi glow plugs are good. Has anyone else had good or bad experiences with different makes?
