Got it, the residual pressure is trying to fill either the front or rear air bags on the passenger side. Can you tell if the exhausted air is coming from the front or the back?
There are two ways this can happen in the scenario that you have described. One, the travel solenoid six pack valve is leaking on that side. The Height control valves always have system pressure. It is the travel solenoid that isolates the HCV from the air bag.
Two, the raise solenoid valve is leaking. The six pack always has system pressure from the 3/8 line entering at the end of the six pack. If the raise solenoid is leaking by, then the system pressure will flow into the airbag until the pressures are equalized.
