P38A Glow Plug Relay, power in but no power out?

Andy Cash · Jul 22, 2015

Hi Guys

I am having problems with my 1999 2.5 DSE glow plugs. There doesn't seem to be any power leaving the glow plug relay to the plugs themselves.

I have power going to the relay but that is as far as it gets.

I have also changed the Engine Coolant Temp Sensor (green one on side of black towards the back) as i read that this may cause a problem, but to no avail.

any suggestions or pointers for what i could try next would be gratefully received

many thanks

Have you checked the fuse (80 amp I think) in the engine ECU housing?

Hi Saint.V8, thanks for the reply!

doesn't seem so, although I'm not an electrical wiz! is there an easy way to check? couldn't hear it clicking if thats any help? i did replace it for another but it was a used one, perhaps with the same problem?

regards

Is there a hotfix on it?

Replacement temp sensor reading OK?
