Air Suspension is acting odd

Hi Guys,

I've been getting a rear left air spring empty every now and then lately.
I hear that when I wake up the X compressor starts pumping and there's a particular sound like the reservoir is empty,some sort of whistling when it starts to pump.
So,I was trying to research here and had no luck,although I saw few people's posts.Some have replaced just a left air spring and got the same result after that.
I am not exited about overhauling the suspension right now,but the winter is around the corner and I wouldn't like my wife to get such a thing while she's alone with a newborn.It's good if it pumps right away,but what if it doesn't....
Anyway...where do I start checking?
Should I give it a battery disconnect treatment?
Recently had a carsoft hooked up and found a Pile of codes,nothing serious,but yet...some O2 inactivity and so on...did I get the gremlins...again

It depends on the surface it's on,for example:
I park in the garage,get a bit deeper in and it's on the well leveled pavement and no dip in the morning.If I stop a bit closer to the gate,all wheels are on uneven pavement(it's an old asphalt sunk by the weight of the car) and I get it leaning to the left 2 nights in a row.
This afternoon it sunk in just 1 hour after I came back home,so....no puncture,an air spring is fine...control unit? Gremlins? Height sensor?
IDK

так вот в #78 OP пишет что проблема таки была в воздушной падушке(пружине).Он поменял одну,но она была с браком и пропускала.

Они по 170 баксов за штуку.
