2019 G31 520d Touring, 40k miles, nearly 5 years old.

Came out this morning, started the car, to be greeted with a 'chassis limitation' message and the rear suspension dropped to the deck as I started to drive off. No previous errors or warnings, car has stood for 5 days but was running fine. The car says it can still be driven to the dealers but is this a good idea - obviously it's very 'hard' and low!
Is there anything obvious I can check like loose connections in the boot area etc?

It's booked in for an oil service next week anyway, but this got me thinking and I looked at the last one - which was Jan 2023 and 12000 miles ago. I thought the intervals were 18k miles so why has it dropped to 12k now? Not that I'm worried as I don't agree with BM's long service intervals anyway, just curious really.

Any helpful advice appreciated chaps, ta.

Thanks for the replies.
For health and time reasons I really can't do much myself on it for the foreseeable.

This afternoon I drove the car up and down the drive, changed the settings from comfort through sport and eco and back to comfort, and nothing happened, suspension still on the deck.
Put the car in the garage, switched it off but left it unlocked. Five minutes later a whirring sound and the compressor pumped it back up to the right height, and it's stayed up since. So hopefully that means the compressor is Ok and the airbags are not leaking.

I'll see what it's like tomorrow and probably get our local mechanic to see if he can read codes.
