Yes mate
I have had most of it out and disconnected to check connections and wiring.
Bone dry down to the floor.

CAN BUS should be re-named CANT BUS
Do you have the rotary gear knob? If yes it the 8speed.
can you not get all those faults in one doc (maybe phone not the best way to do it)

You’re right there bud, I will try to sort that out!
Yes rotary gearbox and I'm pretty sure they only mated the tdv8 4.4 to the 8 speed box.
The strange thing is sometimes I clear the codes and every single code disappears and the car is perfect, everything working as it should and it’s a joy! And half hour later it’s a **** pig.
To clarify I run a small garage and know my way around a vehicle, but by no means am I an expert in range rovers!!
I currently run a discovery three which in hindsight I have been pretty lucky with.
So not having this on the road is not a major issue but it is really starting to irritate me!
Tomorrow I will pull the fuse box under the n/s glovebox and check all the connections there.
I will get to the bottom of it, it just may take me a while and all help is gratefully received.

Tell me about it!!CAN BUS should be re-named CANT BUS
From what I can see on your faults. Yes they all seem to come back with testing the CAN, bad grounds or power to a module, and even corrupt CCF.
So testing CAN bus and see what happens. I don’t honestly know enough about testing can bus to advise. I only know some basic testing can be done with normal equip.
there were a couple of guys talking about it on here a while back, think @gstuart was one.

hiya
alas I’m not familiar at all with this model ,
U codes can normally be ignored
if both keyfobs suddenly stopped working I’m wondering if maybe the RF transponder unit in the roof has maybe failed , easiest to use a multimeter to test between the KVM and transponder for continuity
indeed and also agree ref connection/ wire , haven’t seen many replace a RF unit but instead found bad connection , inc the earths points as well
plus doesn’t take long to do a continuity test
know a low battery can cause havoc , or even a blown bulb can light up the dashboard like a xmas tree
Right gentlemen
I think I may have had a bit of luck, after stripping practically everything out of the rear of the car and having no joy with connections etc, I then removed glovebox to check connections to the junction box which, again all seemed clean and dry, I then went under the seats and started checking, under the n/s seat just seems to be a tv module or poss telephone module, either way no can bus wires to it, then under drivers seat I found the seat control module (climate seats) with plenty of can wires to it.
I disconnected this and tried again, now the only codes I am getting back are the speaker codes, which have been pretty much hard from the start.
I have road tested, although only five or so miles and still no communication or med speed can bus codes.
Obviously the climate seats no longer work but everything else seems to have healed up!
The question is could this module, either shorting or open circuit, cause this sort of catastrophic failure ? also, why would I get no climate seat codes when disconnected.
Thoughts please
