As far as I know the FL2 duddun have a VCU but a Haldex instead, adjacent to the rear axle.
… No VCU on F2
And AFAIK, no simple way to run it as 2WD, as the haldex is actually part of the rear diff

What are you trying to achieve?
Pulling the fuse (or disconnecting the power) to the Haldex unit will remove drive from the rear 'axle' - but put several warning lights on, the only 'drive' then going to the rear will be due to the viscosity of the oil in the Haldex unit, maybe 6% at best. IIRC the lights that will be on would cause a MoT failure if presented for test.

I know nodge has had to run his 2wd for some reason but like others said no VC but haldex instead.

His diff seized !! Design fault that LR never rectified. Locked up and he skidded to a halt.
Pinion pre-load set far too high from factory.
Lucky he wasn't injured.

Didn’t JLR sell a 2wd model. Wouldn’t it just be easier to get one of those or at the very least upgrade (if you can call it that) to a 2wd Disco Sport/Evoque.

Can you not then just remove the prop shafts?
I think I read it causes issues in the F2.
If you simply pull the fuse on the Haldex, it throws the computer into a hissy fit and you lose functions.
If you have an issue in the rear diff or the haldex, that would still be spinning though the rear axle anyway.
I guess it depends on what the issue is/why you’d want it 2WD?

Presumably the reason to want to remove it is wind up - so with the props removed, it could not create wind up.
I could see how it might damage an already damaged Haldex further, but can't see how it would damage the transmission.
It might start throwing Amigos or summat if the input shaft to the Haldex is not spinning as fast as the diff end though.
Maybe some company will come up with a more fancy version of the F1 IRD pinion removal blanking plate for when the Haldex is removed from the diff on an F1. It would need some electronics gubbins though to fool it into thinking the Haldex was there and working.
Or maybe you have to remove all the transmission between PTU and wheel stub axles (ie props, haldex, diff and most of the drive shafts - but you'd still need some electronics gubbins - unless the computers can be set to think its a 2WD (ie an eD4).
