My 2016 W900 just started leaking down overnight on both the suspension bags and cab bags. Talked to couple other guys having similar issues. No audible leaks or breaks. Will build and hold air and a load fine. Was thinking it could be Pressure protection valve off the tank. Any suggestions? Thanks

Check the fittings. A lot of those use the push in fittings, which aren't the best for longevity.
