Yesterday as I was leaving an RV Park, I went through all the normal procedures, i.e. air up, slides in, jacks up. The engine had been idling perhaps 10 minutes or so as I hooked up my toad. As I started to leave I tried shifting into drive and the indicator showed “d n”. I then noticed that the air gauges read about 65 psi. I turned off the ignition, turned it back on and the pressure came back to normal. I drove home(70 miles) and the air stayed over 100 psi all the way. Any ideas as to what caused the air to drop?

I personally would not start the engine to air up until the jacks are up. It is possible a jack had lifted the chassis high enough for the height control valve to be in its exhaust position so that air was leaking out. You may also want to put the engine in high idle when airing up.

Sometimes these systems just brain fart. I always tell people that when something doesn't work right, try again and then keep an eye on it. Almost everything has some kind of computer running it.

I see "Algoma's" point, but I do mine differently. I don't like when the coach drops down when the jacks retract. On both of my DP's, I always started the coach, let it air up and as soon as it starts to lift off of the jacks, I hit retract all. It lessens the severity of the coach dropping.

On a couple of occasions over the four years I've owned the DS, it didn't want to air up the bags. I momentarily put it in drive and the bags inflated. Again, I think the systems occasionally brain fart.

Thanks for your thoughts. My coach is an 2014 DS 4369. My hope is that it was a computer glitch/brain fart and no more issues.

Thanks that makes sense.
