Stop car to low

I have problem, with my self leveling air suspension, i keep losing air allmost everyday, it suddenly sags to the ground, and i get the (stop car to low) warning sound,.when this happens, i hear that the compressor is going nuts!
And everytime, the car rises after 10mins each time

I am loosing air, near the compressor,i think, i will try to connect the star tomorrow, it dont sag overnight....
Can the compressor get a internal leak, when it starts to fill air in the springd, it uses 60-80sek, to get full height

Internal leak, like wear out piston ring?
This is pretty complex system orchestrated by computer with program written by weed sniffer.
It takes some leg room to troubleshoot it.
If you can disconnect the compressor, check how many psi it can pump.
Rebuild kits run for $15, so doing new ring is not taking rocket scientist.
