Could a low battery cause the Air suspension to deflate ? or not "keep it up" so to speak ?

Interesting observation....

Dont know, I could ome up with a rationale by which a failing battery (ie unable to hold a deep long charge) could allow certain modules to go into an odd mode and lead to leakage.

How old is the battery? If you read up on this, you will see that they can fail in strange ways.

Battery is as old as the X5, so 5 years now...without a doubt it has to be changed, just wondering if that can cause the suspension issue ?
