Hi Scotty,
I have a 2016 BMW X5, 45,000 miles. The other day car was "jumping" all around and was very stiff at the back. I stopped the car and saw that the two rear sides of the car were very low, both sides. Looks like the pump didn't feel the air suspension. No error/warning code on the car dashboard. I closed the car and opened it a few times, and suddenly the pump started working, and the air suspension came back up and worked fine.
I took the car to my mechanic. We checked the suspension bags and the system in general and didn't see any leaks.
We connected to the car computer and scanned the system. No error codes were found by the scanner.
We performed an air suspension purge via the computer. All worked fine (the car deflated and inflated the bags with no problem).
The only thing that we noticed is that one side is at 1mm and the other side is at 3mm. Not sure if it is related to the problem or not. I did notice that one of the tires was also worn significantly more that the other. Is it related to the problem?
The car was fine for 2 weeks, and then it happened again. All was deflated. We turned off the car, turned in back on, and all started to work fine.
What could be the problem? Where should I start?
Thanks
Steve.

It seems the issue is related to the electronics since when you restart the car, it is resolved for sometime. It is not an easy job to find the solution but the electronic issue is not uncommon for a 6 year old BMW. You may take the car to a BMW specialized shop for diagnosis.
Thanks, Yaser. Guess I'm getting to the point in which I need to get rid of it 🙂
Seems like a wise action.
It sounds like the system is just glitching, which isn't surprising considering its advanced technology that's aging. You may need to talk to a BMW expert who's seen these systems before.
Thanks. "glitching" is exactly what I'm afraid of 🙂 It can cost a lot of money till you find where the glitch is.

yup.
Who knows, it may just be a control module of some sort that needs to be replaced (just a guess, ive never worked on one of these). But, probably safe to say that similar issues like this aren't too far behind.
Id still consider getting out while you still can. You may want to go to like carmax and sell it there, idk what you'll be able to get on the street for it.
Thanks Bro
