air horn like sound? 2006 CLS55
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?
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.
