When and how was the battery voltage taken?- 11.5 volts way to low.
Edit: after studying the graph again I see that was when cranking, 9.5 v when cranking is min without throwing faults, on the last graph battery voltage (I think) the voltage takes a massive drop towards the end, why is that? there doesn’t seem to be anything wrong with the alternator, the graph is very poor quality on my Ipad, cylinder offset is only measured at tick over revs
Live values on the Iid tool is you friend and keep graphs as simple as possible.
The readings on the oil temp sender is suspect, I am surprised that hasn’t been picked up. I would also check the engine to body earth is good.
I think fuel ramp pressure should be translated to rail pressure.It can when others can't,
It will when others won't,
It goes where others don't.

Yes, battery measurement taken while engine was off. Not 100% sure why battery degraded so fast.... alternator voltage seems healthy while engine is running.
I think it makes sense to wait for new battery before moving forward. But seeing that faults usually come out after at least a few tens of miles of a drive, I suspect this is not battery related.
I would note that the faults seems to come more often once they showed up (i.e. Seems like a warm engine leads to a more recurring issue).
Feels like this is sensor related (i.e. Once warmed up, sensor misbehave). Now... I assume that this could also be the case for something more mechanical that lives in oil.
Not sure how the HPFP failing feels like.... maybe someone here has such experience?

Oil sensor is throwing a code (out of range from memory). That could/would not cause cascading errors, would it?

Doubt it, I've had that occur from time to time with a few D3's without any other issue involved. What other codes are you getting from engine ECU? Forget about U codes!yµ (idµ - eAµ) ψ=mψ

Here are the codes (approximate translation from French to English)
P2290-00 (6C) Injector Control Pressure Too Low
As it turns out.... Only one during that "run". But it repeated
( on 08-08-2018 10:18:50 at 212996 km ) P2290-00 (2F)
( on 08-08-2018 10:23:55 at 212998 km ) P2290-00 (2F)
( on 08-08-2018 10:33:35 at 212998 km ) P2290-00 (2F)
on the 9th, also got that one:
P0087-00 (2F) low fuel rail pressure
On the 6th, got more variety:
06:40:41 P117D-00 (2F) Fuel regulator - volume has exceeded maximum limit
06:44:57 P0087-00 (6C) low fuel rail pressure
06:47:23 P0087-00 (6C) low fuel rail pressure
06:50:45 P2290-00 (2F) Injector Control Pressure Too Low
06:52:56 P0087-00 (2F) low fuel rail pressure
06:59:26 P2290-00 (2F) Injector Control Pressure Too Low
07:05:53 P0087-00 (2F) low fuel rail pressure
07:09:15 P0087-00 (2C) low fuel rail pressure

These codes seem to be indicating either a fuel flow restriction or insufficient delivery. Did you change the fuel filter for an original? Also, make sure the connections are in the correct order if its the early type filter. Battery needs to have 12.5v min at rest, other than that you might have to look at the lift pump delivery!yµ (idµ - eAµ) ψ=mψ

Hum.... I thought that in case of low pressure pump the high pressure pump would raise another error (something about cavity).
Fuel filter was replaced -after- the issue started. Not sure by what type, but will check.

Fuel filter is of the "new" type (you only replace the cartridge/element) and was replaced recently (twice) since the issue started and is a "Britpart" brand (LR009705 - GI17080930).

OK, I have had issues with that particular filter on a couple of occasions which resulted in fuel rail pressure faults. Problem was resolved permanently with an original LR filter. I think it best you rule this out now, or you might end up going mad if later on you find its the real cause. If nothing changes after replacement we can look at the lift pump (in tank FDP)yµ (idµ - eAµ) ψ=mψ

If you are going to take a look at the fuel tank delivery side of things, Robbie has put together this excellent "How to" which will take you through the system in clear and logical step by step approach.

HPFP. That’s what sorted my D3 out when I was having similar problems. Did you run out/low on fuel. I did and problems started not long after.
Plus don’t go back to the two dealers who are saying one of the turbos are fault. Unless I’m mistaken D3’s only have one.D4 MY15 SE TECH
D3 gone but never forgotten.

One of the dealership insisted on replacing the air compressor because it was "slow" (but no associated code).... 1500 euros later, nothing changed. He is not seeing that truck again for a while. (they also did not put the "old"/"broken" compressor in the boot as instructed).
Not running out of gas in the past. I hope it is neither the low pressure or high pressure pump... In both cases just the parts are expensive (but less than a 1500 euro compressor.....).

An update on this issue since it could be (somehow) useful for others: we do not know what the problem was, BUT, after leaving it at the dealership and having them unplug "stuff" and plug it back, the issue is not reproducible. Unfortunately, they did not keep track of what "Stuff" was unplugged and replugged.....

I know your leaning towards your fault being either poor voltage or a fueling issue but my D3 did this too (Limp mode, Terrain Response Unavailable, Gearbox Fault etc...) and it was the steering sensor. I took it to the local Land Rover Ind (before I had my IID tool) and had them reset it (five minute job) and its never done it since. It cost me £20 at the time so perhaps worth checking?
