I have an 06 STS with automatic level control that I can't tell is working! In my 98 STS, whenever you turned the car on, after a few seconds, the air replenishment cycle would kick on, turning the compressor on for a few seconds and then it would turn off. Also, just by me getting in and out of the car would cause the system to activate and level as well (I'm 190lbs). It was very sensitive. I can never hear the compressor come on in my new car at all. I will listen for it when I activate the ignition, I've tried getting in the trunk, I've even listened for it when I have a car load of people and I can never hear it. I received service manuals for the car and it is supposed to have a compressor that operates the same way as the 98 meaning it is also supposed to go through the air replenishment cycle and level when weight is added. I have had the car for 7 months now and I have never heard the compressor. Does anyone know if the new compressor is MUCH quieter? Has anyone heard their compressor come on? Just curious if something is wrong with car or with me?!
