I agree with you that there are elctronic ride sensors for each wheel. The air line for the two air bags on the left drive wheel are tied together. I believe the tag air line is separate. The control valves for the air supply to each wheel are not at each wheel. They must be with Hadley control system. The coach does not have traditional RHC valves that are mechanically connected to the axel- only electronic sensors and air lines to the air bags.

Trying to find a leak that is so slow will be difficult. So I plan to live with the system the way it is for now. For all I know we have had a slow leak in this system from the beginning. The manual says that it is not designed to be leak tight.
Thanks for help.
