My bag won't leak at night when I'm high!

[Clutch]

Ok, another air-suspension thread. I've read dozens of them but can't find a mention of this - I too have the right front suspension sagging/leaking overnight, yet not all the time. There is no pattern to when it goes down and when it doesn't. Some mornings it hasn't moved, some mornings down a little, and some mornings practically touching the tire.

And here is the twist - if I raise the ride height before turning the engine off, it won't leak at all - it will stay at the high height for days and days as long as I don't drive the car! So, I am confused about how it can apparently leak overnight from the "normal" position, but not from the "high" position? Is it a two-stage bag or something like that? Thanks in advance for any insight fellas.

PS - I have no other ride-height symptoms while driving - no sagging, no noises, zip.
