Hello, I currently am having a problem with my front right airmatic shock. I have 100k on my car now. I replace the front right shock at 50k/4yrs ago and the front left about 6m ago (both with arnotts) the front right shock sometimes will drop while parked and sometimes it holds air. What's weird is after going through both front shocks failing before they would take forever to pump up air. my situation now is different, the car pumps up quite normal. but sometimes when I park, sounds like a value is left open for 10-15seconds until it stops hissing by itself and I can his it releasing air pretty quick as the car drops. today driving on the interstate I received a stop car, car to low warning. so I pulled over and seen it was bottoming out. restarted car and was pumped back up in a matter of 10seconds to normal ride height. so im curious if anyone has had this similar problem. To me it doesn't seem like a leaky airbag but more of a release value issue.


please any advise or diagnostics I can perform will be appreciate.

anyone have an issue with this valve?

after doing a little more research, ive read that the pressure relief valve on the air compressor could leak. but if that's the case, wouldn't more than just the front right airmatic deflate when parked?

It could be strut itself (internals), check for leaks - pressure line to strut & central valve @ compressor (post 2):

VL = left front strut
VR = (FR) right front strut
HA = (RA) rear axle distributor
P = COMPRESSOR
SP = reservoir in trunk

Just an update. I was starting the car and the front right bag wouldn't blow up. Then after an hour it decides to hold air. I'm jumping the gun, but just order a new strut. My Indies says if the control valve was bad, probably would throw a CEL. Just weird how the strut works randomly. And this will be the third strut on that corner at 100k. ;(

So, the front Arnott failed with 50k on it? Are they going to honor any warranty?
I am thinking about buying Arnotts for the front of my car.
