Driving fine on trip. Suddenly level system and beeping. Air pressure at 70, limped into piolet store. Turned off engine and pressure dropped to 50 and holding. With engine running at high idle won't go any higher than 50PSI. Any suggestions? Mobile service is on the way. Back right corner looked like not at ride height. Not noticing/hearing any major leak off when I turn off engine but I am sitting beside an idling semi.
Turn on the engine and go to the low corner and see if you hear the leak. Guessing blown air bag.
Yup, either a massive leak which you should hear OR the air governor is hanging up. New air governors are under $25.
The leak is in the suspension system and not the breaking system. there is a safety pressure valve that prevents a leak in the suspension system from draining the breaking system as well. that valve will engage at about 60 lbs.
in the wet bay under the drivers seat are two switch valves that are subject to corrosion. they activate the alarm on the dashboard. I have had those go out with similar results to yours. I could hear the air escaping with the engine running so it was fairly obvious.
Back in business, mobile repair stopped by Within 15m and tightens the line coming off of compressor
Aired back up and on the road again. No charge! Some clean threads were showing. 2minute repair
Glad to hear.
Curious to know why the one low area as you stated and not the entire coach being low.
To answer your question lt403, in this case it was probably just unlevel ground the coach was sitting on..
