Possible air leak

[Guernsey]

I have a 2014 Anthem DLQ. I can hear an air leak in the back engine compartment on right rear side with engine idling. No issues airing up the suspension or driving down the road. When parked, I do lose most of the air within a day or two.

Anyone have similar experience?

I had that on my 14 just before I sold it. It was the rear right height valve. Any shop the does truck suspension can change it.

If it's coming from the immediate right-rear then it could be the air governor or turbo protection valve on the air dryer. Easy to find out. Just open the right-rear bay door. You'll see the air dryer so check if there is any leakage from the purge port. The air governor is also in that area, probably to the far left. Check for leakage at the governor as well. It could also be a leaky line to the compressor, which you can see by opening the rear door. If everything looks well the leak is probably a bit farther forward but echoing through the engine compartment. In that case it's most likely the ride height sensor that Chuck mentioned.

Thanks I have some crawling around and spritzing water on air lines ahead of me......

Had all the filters changed once in that area, and the tech let the gasket fall off the air dryer filter before the filter was installed, and then tightened way too much, and air was leaking from there. I thought it was other valves around the air dryer, but it was the gasket not on the filter.

Coach ran fine, but once I stopped, and was at the rear of the coach, I could hear it.
