      VIDEO - Ok, found out it airs out weird sometimes too. I haven't had air very long, but I adjust my ride height as I go, usually running around 45-55PSI. If I go to air out a little on the road, it will just do this, usually on the first try. I was just messing with it a lot because I knew it would eventually do it. Side note: its my driver's front.

      Also note that I'm the one airing it up/down quickly. When it makes the 'duck' noise and the yellow (left) needle drops far, that's what issue I'm having.





      Alright, so I have 8 SMC valves, and this switch box. When I air up, I usually do the back first, and then the front, using the back up, then the front up switches (individually.)

      Today, I watched my gauges, and when I aired up the back, the passenger side rear went WAY higher than the drivers side, and just kept inflating. I quickly aired it out and it stopped. The front did the same thing, but ONLY on the passenger side. It's happened a few times now, it's not every time, and it just started today.

      Now, if I air each bag up individually, it doesn't do it, but that could be the fact that it happens intermittently.

      Any ideas? I have yet to check grounds/power yet, but I really can't think of what it would be.

      Bump for halp!

      Also, when I let out the front left it lets out too much sometimes. I can only describe it as a 'fart' noise. I know, I know - technical stuff. Switch box maybe?

      its because you drive that ugly colored mkiv.

      im imagining your up valves are sticking and when you air down while its stuck open it will give it the release of pressure to close the valve.

      thats the only thing i can think of

      *edit* and because you left san antonio

      very common problem with individual valve setups. alot of things will fix this. Just needs a little bit of back pressure. if you run a PTC off your dump with a pice of airline thatll fix it, or a muffler, i personally have my dump lines run outside with a 1/8" barb fitting to slow it down and correct the problem

      Ohhhhhhhh ok. I could just run mufflers on them I suppose. This is my first air setup, so I didn't know this was a common issue.
