    I'm loosing air from the release valve on the other side. Is the solenoid bad? Anyone fixed or replaced one of these?

Are you sure that is the leveling system? Where exactly is it?

[David and Teresa]

It's in the 3rd bay back, pilot side, the bay in front of the plumbing bay.

Heard, and felt the leak. A couple days later the coach is low, leaning toward the right.

[encantotom]

all of the leveling solenoids are usually in 6packs front and rear.

do you know where the airlines run to from it? those look more like the solenoids that operate something that is air powered.

looks like dump valve solenoids

[David and Teresa]

Could they feed the bathroom doors?

Looks like a dump solenoid to me also. Mine is in the same compartment as the AH. I had a leak there also about a year ago.

[encantotom]

There is probably no carpet in the bay where the dump solenoids are more likely something else

Where exactly was it leaking at

It's like the solenoid has the valve open. Air is escaping from the filtered output.

With that solenoid leaking your 120 volt compressor is probably not able to keep up with the air consumption and may be shutting off from running hot. So if you have a slow leak, which many coaches have especially on cold mornings, then the suspension could drop.
Not sure what that solenoid controls but like others said it is not for the leveling system. If it is not something that is critical for day to day operation, then you could bypass the solenoid by plugging it off until you can replace the solenoid. Any hardware store could fix you up something to plug the tubing. Looks like 1/4" tubing? Just don't leave it bypassed.
