Is it holding at warmer temperatures thru the day?
You said it yourself that compressor is pumping it up, although required few cycles would indicate deteriorating performance.
In your shoes I would start with compressor service/overhaul. I made pictorial about it.
My first guess would be that moisture in the system freeze something.

If it holds for weeks in warm weather, but drops in freezing temperatures, that should give you straight pointer.
When was the last time you serviced the compressor?
I bought my wagon with over 140k and had intermittent suspension warnings, till I finally bought rebuild kit.
Doing the service at the end of very long dry season, I found the drier soak wet, so evidently there is design flaw in the system.
If you keep filling delicate electrovalves with moisture and park the car in freezing temperatures, that is asking for troubles.

Good you found leak source, but I am afraid you might have more issues.
Leak on supply line will not drop the suspension, unless valves on bags leak in the row as well.

Kajtec1,
Took your advice and replaced the right rear spring that was bottoming out in cold weather. Upon start up the right is about an inch shorter than the left side.
Today I will replace the air distributor and see what happens.

If the bags are sagging overnight, you have a leak in the bags. There is an isolation valve that locks them off from the system when the car is off. If the car is sagging overnight, it is 100% a bag failure.
