Technical EGR valve fault?

[Granvilleb]

I had the loss of power, the engine going into a "get you home mode". I followed the suggestions in the EGR valve thread but it did not rectify the fault.
It was on the engine at start up and the yellow triangle was lit. I then thought was it the glow plugs as the mornings had gone cold and at 55000mls it is shown in the service schedule to check the glow plugs. They all had the same resistance reading so they were all working but I didn't know what the reading should be so I replaced them. I still had the fault. I the looked at the glow plug relay and found that the main battery lead was not very tight and there had been heat there as the thread and the plastic were damaged. I cleaned the parts and refitted the relay and the fault had gone. It took 5 engine starts to make the warning light to go out. Now at the start of this winter I got the same fault again. Removed the glow plug relay and found that the main battery terminal was not 100% tight. The last three threads had been damaged and I hadn't noticed the first time. I fitted a washer to cover the threads, tightened the nut, refitted the relay and Bingo. SO don't get too technical, think what it could be before delving in.

I suppose it is so easy to expect the worst when engine warning lights start flashing their warning, and yet the simple tightening of a bolt cured all your woes.

Indeed a lesson to us all here.

Where is the glow plug relay located ie. which one is it? Thanks

It is on the bulkhead near to the brake fluid tank. It is held on by one 10mm nut.
Once it is loosened you can remove the connectors and then turn it to get at the main terminal underneath. The connectors are not the same and will ony fit one way.
