    My Disco has lately been loosing the air from the rear suspension bags when parked. It replenishes when I start it, so I know it is not the compressor. It will also stay raised (even for days) when I raise the rear and then park it, so I know there is not a leak in the bags themselves. I believe it has something to do with the relief valve (or whatever regulates it under normal "leveling/parked" actions).

    I'm hoping I don't have to replace the entire system, but don't really know where to start.

    Yes, the entire system is probably worth more than the vehicle itself, but I'v had it for over a decade and I'm a very loyal person (it's never left me stranded). :)

    Suggestions anyone?

    you could try spraying the connection points with something like simple green and listen after you've had it fill up.

    obviously you could also convert the rear to steel springs if it becomes too annoying.

    So, it's obviously leaking during "normal" settings, but NOT when I choose the "lifted" option and leave it...

    Not sure what the spraying it with simple green would do, unless you feel that it might "clean" the contact points that you are suggesting are the culprit during normal settings?

    spraying something to bubble if air is escaping is so you can see or hear it. how else do you plan to find a leak?

    not sure what else

    my point is more that if it was "just a leak" it also would leak when in the raise/lift position... it does not... info points to it being a controlled leak problem instead of a generalized leak (hope that makes sense).

    are there two different ways it may leak/dissipate air from the suspension? just baffled on why it leaks while in normal, but not in raised?

    ...it also raises and stays raised while the disco is running.
