2000 D2 TD5. I’m getting what sounds a bit like a pressure release from my ACE valve block every 10 or so seconds. It’s definitely coming from the ACE valve block. It definitely isn’t the rear air suspension. The ACE valve and lines aren’t leaking except at both fittings on the ACE Ram where there’s a small leak.

So with my new Nanocom, here are the ACE settings. Could someone please tell me if the values are normal? I’m wondering if I have a pressure valve issue. Values were taken whilst engine was running with the ACE relay removed and bridged with wire.
