Autoride compressor diagnostics

[Writefast]

So I have what should be a failed auto ride system. The bladders have holes. And I, as the new owner, have never heard the compressor cycle. A few questions. Why is this not showing up as a fault code? I’ve put the VDiagtool on it a couple of times now it it’s showing no faults there. It shows a few faults, but nothing related to suspension. That’s my primary question. Why does the same system that can tell me my lumbar support in my seat has failed, can’t see that a major suspension component has or may have failed? How do I diagnose the compressor? I want to get this system back up to spec but I don’t want to buy anything I don’t have to. Because I’m cheap.
