You can upgrade your IID tool from the G3 version you have to the latest G4 version via the GAP website. You just post the old G3 back to them and they'll send a new G4 out to you...
The Gen 4 IID tool has full coverage and support for the D5...costs £220 for the replacement though. Still cheaper than buying a brand new Gen4 IID tool...that'll sting your wallet at £550.
I did the G3-G4 exchange when I bought the D5. Bought the G3 IID tool when I got the Disco 4.
Wife came back in car , and is it me or is it missing a relay ????
Certainly looks like it...could that be the one for the FBH perhaps? I wish I could get out to mine so I could check against that photo...definitely a no go till this storm has passed. I'd end up being blown over to Norway...it's wild and getting worse

When you do get chance please post a pic of the actual relay so I can get one please mole
It's really hard to tell...could have been a previous issue and a fix by some indy garage mechanic...or it might be nothing at all.
Even checking yours against mine, we've both got the same 2017 year of manufacture...but yours is an HSE lux and mine is an HSE. Could well be some differences in that rear panel due to you having the rear entertainment, electric sunroof, cabin mood lighting etc that I don't have...
I'd stick to why the FBH isn't working as a first port of call before we go comparing pics of rear fuseboxes...but of course I'll do the pic thing once this storm has blown over
The junction box central should be the passenger compartment...assuming the engine compartment is the front and the boot (RJB) being the rear one.
In the passenger compartment fusebox...like we talked about yesterday... the 5amp fuse covering the FBH is F27 on that board. The diagram doesn't assign values to any of the relays in there though.
Fuse F27 covers the FBH, TPMS and the front of the roof console....I can safely assume that neither your TPMS nor the roof console have any issues, so that would rule that fuse out.
I'm still none the wiser as to what the relays in that fuse panel cover...I can find no listings for relay functions for any of the fuse panels at all. So, unless it's clearly marked on the individual fuse box covers...I've no idea what they do
The best bet in the meantime is to set the Timed climate thing on the centre screen to fire up in 5 minutes then go out and listen to see if you can hear the FBH running...it's loud enough to hear if it's working.
Normal rules apply then...check at the plug if it's getting power (12v) when it's switched on, if it's got power and it's not running...it's mechanical...or an internal electrical fault within the FBH itself.
Then we can go looking for why it's not got any power if there's nothing at the plug... if that's the case
