Glow plug relay in Freelander TD4 2003

Hello all,
I have a Freelander sport td4 2003 with typical starting probs (hard starts in the morning, lots of white smoke, no symbol of glow plugs...) and I've been told to replace the glow plug relay just to try some solutions. I've been looking for information on this web but I found where exactly are the relays in freelander'98 not in mine. My car has no relays under the fuse box in the engine bay and I can't see the three relays that a lot of people are talking about (two yellows and one black) that control the starting.
Can anyone help me find the black glow plug relay of my car?
Thanks for the info.

The glow plug relay is in the E-box (between battery and fuse box) they're not really a common failure.

Not sure it's cold enough for Td4 glow plugs to operate yet, assuming your in the UK.

Thanks Chaser! I've found it with the instructions but unfortunately it was not the relay.
Thanks a lot.
