My AR has just developed a problem with the air suspension system, the warning light comes on after you pull away. The suspension is stuck at the top setting and befor pulling away with the system working in manual when you try to lower it the green lights flash as it should do to say that the system is lowering but before it actually lowers the warning light comes on again. I suspect that its the air release valve but need to know if it would cause this problem, anyone know how this system works or the pinout connections at the management unit.
