Rear air suspension

Could this be a height sensor or similar when I leave the car in normal mode the rear drops down on to bump stops, seems the drivers side is the lower side this is approx after 10 mins. if before I stop the car and press the up suspension button and let it raise to max height it stays up all the time therefore suggesting to me it is not the air bag Thanks for any help

Disconnect the battery immediately after u leave the car, or unplug the connectors from the valves...if it will not drop then as usual it's a management issue and we'll speak again. if it drops even with battery disconnected it's a leak somewhere. The bags have the strange ability to seal themselves... yes even in ORM

Will give it a go today thank's
