Has anyone just taken a schrader valve and tied the air lines together so you can fill with an air compressor? My rear air bag was droping on one side but I hears a release of air while parked. Bought 2 new bags but sometimes the car will stay up for days and sometimes it drops immediately when parked.

 

never tried the screder valves route,

but the sinking, what end sinks down?

if you park at level 3 overnght does it sink

if you park at level 1 overnight does it sink?

airbags only tend to leak at level 1 so if it always sinks at level 1 but never at level 3 this is 100% airbag leaking,

let us know what you find

Andy
