After about 6 hours of sitting, come back to my X5 looking like this

Can someone explain to me what the problem is (if there is one) and the cost of fixing it?
Sitting very close to the ground

Rear air suspension failure (hole in airbag)

Check on the Arnott's instead of OEM for replacement.

Super easy DIY. Arnott's replacements are perfect, but if you want an OE I have one for sale on eBay. I replaced both sides even though only one was leaking.

The whole car is sitting this low, does that make a difference in your answer? Thank you btw

Could be the air compressor if both sides are sinking, but chances are one of your air shocks is leaking which could cause the compressor to fail. New Arnotts are $140 each and the compressor is about $250-300. The dealer will charge $800 to replace both shocks and $1000 for the compressor.

I would start with the airbag, because as everyone has said it is an easy DIY. I am an absolute novice and I was able to do both sides in less than 3 hours.

I dont know how the system works but I assume that the car wouldn't sag if there wasn't a hole in the airbag because the compressor doesn't constantly run to keep the system level.

One side down is the air bag, both sides down is the compressor,regulator, or both bags. Generally.....

Does it pump back up when you start it?
