Sounds like a power issue. Failing alt, bad ground, you know the stuff. But thats my first reaction to issues like that. The venting could have been just a coincidence, but during power supply issues the air ride is the first to go offline (well, maybe heated seats).
Once I got home I lowered the LR3 to access mode and then ran it immediately to Off Road height with no problems.
Just another data point:
I plug my IID tool in frequently at the end of a drive while idling in my driveway, especially if I’ve done some maintenance, and have not had a problem with reading codes or looking at live values triggering dash lights. Twice however, I have had the engine start aggressively idling at 1000 or so rpm immediately after clearing faults. I had the same thing happen once on my wife’s XC90 after I cleared DTCs while it was idling. I agree with @DakotaTravler clearing faults while running can cause all sorts of weird behavior. In all instances of the high idle I shut the car off and it was fine on restart. With the LR3 the codes weren’t engine related in either instance.

I’m just bumping this up because it’s a good reminder for anyone using scan tools.

In general, if your battery will start the car, it isn't the battery - this just seems to be a convenient excuse used by LR garages. Do make sure the contacts are tight but that's it.
Using the IID tool when driving is not a good idea apparently - read when the engine is stopped.
If you get the Christmas tree lights, it is NOT the software or new software modules needed. Once more this is one of the old wives tales from LR.
The design of their car softwares is simple though I use the word 'design' loosely. If the car worked when it left the factory then no new modules will make any difference.
The software modules are for each component (like ABS for example) and no matter what version they simply send messages across the CAN bus and read messages they are interested in. As I said though, if it used to work then it still does.
Ditto the CAN bus. Yes it could have problems if you have severe corrosion or something has come off but that's it.
In general when you get odd problems it is a LOOSE connection (since LR have crappy build procedures) and a loose connection on one thing can cascade and give fifty symptoms and hundreds of irrelevant messages.
The two main culprits leading to cascade (suspension lowering, gearbox fault, ABS etc etc etc) are
The steering angles sensor has a loose connection
The brake pedal sensor has a loose connection or dust inside it.
Lower the panel under the steering wheel and jiggles them as you start and when idling. Usually, job done.
I am personally fed up with the constant stream of bull**** from LR about these problems which all stem from bad design and bad build
