Anyone know where the Glow plug relay is?

Hi, I'm having some problems AGAIN with my D8 starting. At 1st I thought it was the glow plugs. I checked the power going to all 4 with a volt meter and they were all dead. In the Haynes manual it says that, this is an indication of a faulty relay. Now the thing is, where is the relay? Am I right in thinking it's somewhere here?:

Is it one under the ECU in that pic?

Any help appreciated. Thanks.

That box contains a few relays as a sealed unit, but I'm not sure which ones they are. I'd have thought that relays to do with starting would be over the other side of the engine compartment in the engine fusebox? I could be wrong though.

In case it's that one that's at fault, it's held on by a torx screw on the side of the box. You need to take the ECU out, undo the two 8 or 10mm bolts holding it in (on under the ECU, one by the washer filler), and that'll give you access to the screw

its bolted to the passanger front wing, near the top of the suspension strut, its black and green and will have to fat black wires comming from underneath it

Ok I pulled that one out today and had a good look at it. It seems to be fairly ok. That's got about 12 connections on it.

I'm still having trouble trying to find the glow plug relay. I can't for the life of me see it anywhere near the passenger strut. I removed the fusebox cover and there's a pink relay there. I don't think it's that.

In the mean time I decided to change the glow plugs. I got some replacement Beru ones and managed to change 3. The 1st one from the left is a F***er! to get out! AAAARGh I can't explain how frustrating that glow plug is. Pug have put this stupid little water pipe right infront of that plug, to make matters worse they've put the fuel pump right infront too. I couldn't get that plug out and I couldn't even get a 12mm socket in there.

Any idea's on how to get that glow plug out without removing the fuel pump? It's in really tight, If I try to turn it with a spanner I'm affraid I will slip the nut.

Did you manage to get that plug out in the end? I have to do mine this weekend!
