2019 L494 Supercharged Front Air Suspension Question

Hi all. 2019 L494 Supercharged 5L v8. The front suspension seems to be loosing air while driving. When I come to a stop it readjusts back to level. I set the suspension to highest mode and turned off the vehicle and it didn’t lose any height/air after 5 minutes. Since I don’t hear any leaks, could the height sensors be an issue or more likely air control valves?

Welcome .

Got any pics, we like pics.

For tech questions you are better off asking in the RR section, but 5 mins is not really a test. Does it drop overnight?
Have you read any codes?
You usually dont hear leaks until its too late and on the stops.
It could be alot of things I am afraid.
