Air suspension losing air while standing

[buddy110]

Good evening,
I noticed that the air leaked out of the passenger side air bags last night. Wondering what would cause that. Started her up and she aired back up, no problem. Any ideas?

Bruce, I am interested in this as well.

I am having a similar problem when I don’t drop the jacks. But it takes about 3 or 4 days for me to really notice my passenger side airbags are low.

If I stay for a week I need to start my coach in the middle of the week to air back up.

I have started leveling with jacks because my air bags do not hold for a week.

The onboard air pump will keep it pumped up if loosing air while on air level.

An air suspension should not be expected to stay aired up by itself indefinitely. A day or two or three...

Now, if you have air leveling and it's activated, then it should of course stay up and level.

My air bags will stay air'd up for months.

Air leveling turned on or off!

I do not have air leveling activated. That said, my Anthem never lost air or if it did, it was equally distributed. The CS only lost air on the passenger side, and it was overnight. I'm going to check it again today.

Bruce, Just an FYI. I overnight checked for air leaks while at NIRVC. Every time you turn the ignition on, air pressure drops 10 psi. Something new on the 21's NIRVC also thought it might have an air leak, soaped everything underneath to find out every time they turned the key on, it dropped 10 psi. I know that won't fix your overnight leak, but it does make it hard to test for leaks.

Also, for some unknown reason the jacks now have a 6 minute air dump delay. Wait 6 minutes before using the jacks for the air to dump, or do the double level trick to get them to dump manually.

My 2019 Anthem had air leaks and I took it to Spartan and they fixed it. The previous owner abused it. Never bled the air tanks with lanyards. Air leaks lead to water in system, which is very bad. Can you take your new coach back to NIRVC?

I have a spartan repair facility near me, but I don't trust them. The last time I went there with a CEL they charged me $900.00 to replace the fuel filter and water separator.

Yeah, I too didn’t have a good experience with local Spartan “Authorized “ repair facility, so I took it to factory where I was very pleased with result.

Long trip for me, but I know they would fix it right the first time

Get the OK from Spartan, you are under warranty if the air leak is bad. Spartan allow 3 psi per hour to be within Specs. That is going to be hard to check with the "new" air drop every time the key is turned on. I guess leave the key on for an hour and see what the air pressure is.

Should I call Spartan first?

Are you saying you have to wait 6 minutes once you start your vehicle to retract the jacks?
