Airbags leaking

I have a 1998 Newmar Dutchstar. Every time I turn off the engine the airbags start deflating. Obvious leaking. Any advice?

There are several components, in the air suspension system that can leak.
Does the whole coach drop , as if your were dumping the air prior to leveling? Or just one corner?
Do the air gauges read zero when you turn the key on , or is one gauge at 65 PSI, and one in the 100 PSI range?
DO NOT GO under the coach looking for the leak without proper safety stands in place.
Freightliner or Spartan chassis?

could be a leaking air dump valve

My Spartan chassis also had a similar problem that was diagnosed as a faulty air dump valve. When it was replaced the mechanic said it was more of an air line fitting problem rather that the valve itself. Not sure if this is what you have but it is one of many suggestions that you will get from this posting.
Cheers and happy travels!!!

My 2000 Dutch Star has leaked some since the day I've owned it. Kind of settled for that's just the way it is, as long as the pump has no trouble bringing it back up and holding it over 100. But then last weekend while out tailgating, I noticed that the front seemed to now drop faster than the back. Huh . . . .

Strange, as our '02 DSDP/Spartan would go several weeks with the bags still aired up.
