air horn like sound? 2006 CLS55
Car in question is a 06 CLS55 AMG
once in a while, maybe 2-3 times in the last couple months, I have heard some sort of wierd air horn honking type sound come from my car
twice it was while parked in the garage, shortly after shutting off
once was while driving around a parking lot
Is this some sort of air resevior releasing due to the air suspension etc? or something else?

Was it more of a whistling kind of sound? I've had a whistling kind of sound WHII-IIIIT (not the Kompressor!) that lasts about 5-10 seconds and the then it goes away. The sound goes from a lower to a higher tone and then fades away. To me it sounds like some kind of a air release or valve opening sound to release pressure, perhaps from the air suspension? I hear this sound maybe once a month and usually it happens when driving at highway speeds or lower (sometimes 20-30 mph, sometimes 60-80 mph).
The sound has occurred occasionally throughout my ownership of the car (CLS 55 AMG 2006). My car was just inspected, and there were no problems, so I guess it's normal. Just like the buzzing sound from the SBC brake system.
