Hey all, new M109A4 owner here. I'd like to share a problem I am having with you guys in hopes that I can track down the issue. My air pressure builds normally and pressurizes the CTIS system just fine. When I go to turn my wheel however, the air gauge drops to zero PSI and the buzzer and warning light come on. Wait about 30 seconds and the gauge jumps right back up to operating pressure. The air assist steering does not seem to be functioning at all and when this happens the transfer case disengages as well (if engaged at the time). My question is this: Is there some sort of overload or leak protection valve that is causing this issue? Seems almost like a circuit breaker for an air system is tripping and cutting off air to the steering, transfer case and gauge. If such a thing exists where can I find it? I'm not sure but there may be an air leak upstream in the air assist steering system that is causing this but if I can't maintain any pressure in the system there is no way to look for it! Help!
