Re: Sound Clip of Air Suspension "discharge" -- Is this normal?
Yep, that's normal. My Touareg and Cayenne, both with air suspension made a similar sound. It's the valve closing on the nitrogen storage tank. Remember, it's under a lot of pressure. If you listen closely you get a similar sound from a compressor when the fill valve closes and you have more than 100lbs of pressure. I've only heard it a couple times on the road and that was when the radio was off and the windows were closed. It happens when it drops to aero height then when it raises as you slow down but it shouldn't cycle. That would indicate a you might have a leak and it's having to adjust height more than normal.
