Hello, can you tell me what happens with the car?

you have 2 valve blocks , 1 front and 1 rear that control all 4 struts , so if the whole vehicle is lowering you may have seepage from all 4 but that is rare. most likely you have a failed return valve on the pump and it is allowing the pressure to drop. when you say the car settles overnight how low does it get? and are you shutting the car off at the raised height or the lowered height?
