Strange Airmatic issue: advice greatly appreciated
For the past couple of weeks, I've been getting an intermittent Airmatic malfunction message, about every other drive. I put it at the back of my tod-do list, as the car seemed to be functioning fine.
Yesterday, during a long drive, I got the red "Stop: Car Too Low" error. I pulled over and, indeed, the front of the car at both corners was quite low although not so low as to hit the fenders/wheel wells. Both rear wheels were the correct height. Cycling the lift button and suspension settings had no impact. The warning went out after restarting, the car seemed drivable, so I finished my trip.
All day, the car was not lifting on opening/closing the doors as it should (soft "chirp," as usual but no hiss of air.)
Today, after searching this forum, i checked the common issues discussed, starting with the fuses which were fine. I jacked up the drivers front side to inspect the strut and look at the compressor. While on the jack stand, I open the drivers door...and, lo, the compressor goes off and the passenger side of the car (both front and back) lifts.
So, I figure AHA! - must be the drivers side strut, since the compressor and other three corners work normally when I relieve the pressure from the drivers side.
EXCEPT, when i jack up the passenger side of the car to test my theory, the compressor runs and the DRIVERS side rises as normal. When I put the car back on the ground, no compressor and both front corners are low again.
Any ideas? Or, do I have to find someone with a STAR tool?

had a problem similar to yours i couldn't figure it out sometimes the malfunction light was on and went off when i restarted the car. I took my car to the shop and the leveling sensor was going bad so it happened only once in awhile and after i replaced the sensor haven't had a problem since.
hope this helps you
