L322 Rear suspension drops both sides very quickly

so today's problem.
Frosty morning, not sure if that's relevant
I start the car and feel it raise a little which I thought is odd, anyway, went to shop, park up and suspension doesn't alter so I thought it might be a strange overnight drop.
Anyway, I get back home and within a couple of minutes both sides at the rear have dropped,
If it was a leak wouldn't it just drop one side?
I'll check for fault codes in a few minutes and see if there is anything obvious.
Anything else to check for?

How did you get on youmite?

Went back out to look, ignition on, closed door, raised immediately to correct height, no obvious leaks, so took key out so I could watch and listen as it drops but it didn’t, and hasn’t dropped by this morning either.
I think I’ll put it down to being a Land Rover and Just keep an eye out if it does it again

That's the problem with electronic units on cars, occasionally there's a fault and then nothing for ages or never again!! I took my bus out last night after a few days of sitting. Limited acceleration!!! Switched off and then on.. not a problem! Yep, it's a landrover

I think it’s just modern cars, not necessarily LR, at least an on/off with the key solves many issues. And 10 minutes with the battery off cures plenty of issues as well, albiet they might come back again
