I have a 2.2dti and the glowplugs are not working.  As far as I know there are 5 things in the glowplug circiut that can malfunction.
1. 40 Amp fuse
2. glowplug
3. relay
4. timer
5. temperature sensor

Firstly am I correct with the above and can anyone tell me where the temperature sensor and the timer is please?

[rustym95]

have you checked the plug its self out as they do go.

[Dave DND]

Got to agree with Rusty on this one

Check the glowplugs themselves - not uncommon to burn out after five years or so

If using a meter, should have a 12v supply to them and pull around 5~8 Amps each one

If testing them on a bench with a 12V supply, DO NOT BE TEMPTED TO TOUCH THEM to see if they are hot - if working, even a few seconds of voltage is enough to take a few layers of skin off. And if replacing them, always advisable to replace the full set, as if one has gone, the others will not be far behind - not expensive.

Tch! As if anyone would be daft enough to touch them after they'd had power on them .......

I`m ashamed to say that I did, many years ago with a Golf one - briefly by accident though, applied voltage whilst holding with a pair of pliers to check current etc for no more than ten seconds. Put it down on the bench and then for some reason unknown to me, I turned around and then picked it up by hand to refit it.

BLOODY  HELL  THAT  HURT !!!

I don't even have the excuse that I did it by accident. I applied voltage to one for just a couple of seconds & purposely touched it to see if it had got hot!

It had!  Ouch!!

The plugs are new, could it be the glow plug control module?
The outside temperature sensor is also not working, would this be connected into the glow plugs at all?

there is a reley in the black box net to bat but cannot remeber if it is in there or colour, and out side temp sensor only dose that out side.

Outside temp sensor feeds the climate ECU with temp data as well. 

[andy4775]

Are we saying that the outside temperature sender supplies the ECU and effect starting from cold?

[rustym95]

no he mean in side car climate ecu on models with climate control,

[rustym95]

as dont know were you are, can you not see if some one near to you may help, its prob a wiring fault or a duf ecu but dont know, put were you are on and some one near may be able to help you.

Up to now I have put in new glow plugs, a new glow plug control module (relay) I have also checked that I have voltage to the glow plugs by pulling the glow plug caps off and putting a multimeter into cap and onto the top of the glow plug and I am getting 11 volts across each one when the light is on in the dash, so I think that side of it is ok.  Correct me if I am wrong, does the ECU need the engine temperature from I think the ECT (engine coolant temperature sensor) is that right?  And that determines how much diesel to put into the engine to start.  This is the first diesel car I have had so I am researching on the internet and what good advice I get on this site as I go along.  I am in Cleveland don't know if anyone is near and if it is the ECU thats gone how much are they? Sounds like they will cost an arm and a leg.

You have voltage at the glowplug ? In which case, everything on the car appears to be working fine, and if the glowplugs are not getting hot, then the glowplugs themselves are at fault.

[rustym95]

is 11v good? is that charged up?
