Hey There,
I'm a RR owner who lives in Austin (like you), and I'm having issues with my air suspension. My RR is a 2006 that had the compressor repaired 2 years ago, but is now riding pretty much on the tires, bags not filling. I've had someone look at it and they said all 4 air struts were fine, and they think it's compressor related. I find that weird being that it was replaced fairly recently. I read one of your posts where you talk about the beads in the dryer being a problem sometimes. You seem very knowledgeable in these cars, and I'd like to get to know mine a little better. If you're ever willing to have lunch here in Austin I'd love to, and if you're ever to provide guidance on the below codes and this problem I would GREATLY appreciate it.
Look forward to hearing from you. dylanellerman@gmail.com
