2013 RR Supercharged, just started getting these two fault messages on start up in the last week or so. Also noticed that the right rear suspension (only) drops down to access mode shortly after shutting the car off, all other corners stay at normal height. Probably about an hour to drain down. On start up it airs the bag back up and the suspension is level again. No issues while driving. Anyone experienced this before? Failed/worn air bag? Or something causing the system to think it needs to drain that one corner only? Looking to self diagnose if possible rather than deal with the idiots at the local dealer/independent repair shops.

Thanks.

Seeing as only you can check the airbags, thats a moot question.
Check the rear bags and see what you discover.
Check all airline connections etc while you're under there.
After that, I'd say it's either time to invest in some diagnostic kit, or hand it off to someone who has it.

I’d look at the ride height sensors first, specifically the right rear.

What are the actual codes? Generic message in the message centre only point you to the general issue. Only pulling the codes can tell you what is wrong.

I'm assuming I need some Rover specific diagnostic equipment to run codes for the air suspension etc? Any suggestions on what product to purchase?

And I will check both the bag/lines and sensor tonight see if I can see anything obvious.

There is an entire section below for diagnostics equipment with lot of suggestions for which ones people prefer. I would check with the folks at GAP to see what coverage their equipment has for the newest generation.

Great thank you very much. One other thing I noticed last night, the terrain response dial is not illuminated 'Auto' at start up and when you turn the knob it says terrain response menus not available. Also when you open the right rear door (that door only) when parked and not running it drains the air out of both rear bags and puts it to 'access mode' height. Only the rear though, not the front. I am thinking this is something more electronic/control module related than anything to do with the mechanics of the rear suspension (bag, height sensor etc). Sometimes I really wish they would just put coil springs in these things.

Land Cruiser's are nice enough rigs if you want coils from the factory. Full of plastic inside, but nice enough.
Your rig is now @5 yrs old, you expected totally trouble free motoring? Brand new ones have issues, of ANY make.
Now back to reality...
Your terrain response wont do anything until the EAS is happy again.
Have you tried to spray the bags yet, in all heights?
Checked the height sensors?
