Nav suspension leak 2008 "L"

Hi all - trying to figure out what to do next...

I've sprayed all connections that could be reached with soapy water, no sign of a leak.

The rear suspension deflates after a few hours of sitting, but it does fill right up upon starting.

I'm not sure if there is something I should do to pinpoint the problem.

I am also wondering if there is a down side to just ignoring it, as it really doesn't bother me to wait a minute before driving off.

I'd appreciate any help here

This may help. It doesn't have to be THAT cold either.

Thank you for that...

You mention that it doesn't have to be that cold. My question is, does that mean that if it continues to leak down into the warm weather months, it wouldn't be the air spring solenoid valve?

Thanks again.

It still could be. It just shows up more when it's cold.

ALSO:

Originally, only the passenger side would deflate. Over time, the driver side started to do the same thing. It was several months before it started to do it.

Should be one per tire.

Ever notice that there's so many high performance parts available for GM products?

Did you ever think that maybe they NEED them?

Is there a way to test the solenoid to make sure it is the problem, before removing it???
And if there is one per tire, what are the odds that both of them have gone kaput in the same general time frame?????

If they're original, probably pretty good. Given they have the same design and made from the same material, their life span from normal wear and tear is going to be near the same. Soap bubble will pick up leaks, a pressure gauge on the vent, a pressure gauge on the inlet to see if it back leaks.
