When the air pressure is up by just turning on the key does it start leaking or does the engine
have to be running.

Sorry I tried to find this post to follow up and couldn't. I had it in NAC and what fixed my problem was replacing the turbo air controller. It controls the variable geometry turbo. That was the major leak and also was killing my boost pressure. It was also why I was seeing the air pressure split. The turbo controller takes air from the primary tank (rear brake tank). The check valves were working properly so the secondary tank (front brake tank) was maintaining pressure. Sooo. Two coach bucks later this big bastar$ is happy again. That's when we headed west and blew a slide seal. Back to NAC. Seven coach bucks later we are headed west again. I remember telling the salesman at MOT that I was not looking for a project coach. I didn't realize they are ALL project coaches. 😂🤦🏻‍♂️
