2003 e320 suspension problem

I need some help I have a 2003 E320 with a suspension issue. The rear driver side drops when the car is off (some times 20mins some times days).I had the car checked out I have no leaks on the air bags, valves or lines, the compressor is new and the automatic leveler is working fine. The only problem is the auxiliary battery. Will the battery cause that problem or what else can I check? I forgot to mention when I press the button to lift the air bags I can leave the car and it will not drop for days, it only drops in normal mode.. (I'm getting the battery changed tomorrow).

Could be an internal valve leak on the valve block, maybe also get the level sensors checked and the calibrated level checked.

Thanks for your input...I already got the level sensor checked and a certified mercedes mechanic calibrated my computer system.I got my battery replaced the only thing I haven't got check out is the internal valve..I guess that's next ..

Airspring on that side. Finding no leaks means only you haven't looked in the right place. I found they crack in the folds at the bottom of the bag and the crack can seal up enough to stay inflated. Park and temps pressures change causing the crack to open leak and down goes the car.
