For the past 10 days, my S greets me when I get in the car with 2 or 3 chimes. Not the sound you get when clicking Drive without your foot on the pedal, but a lovely chime. Infrequently, perhaps twice a day; then not for days. Sometimes two chimes, sometimes 3. No consistency. No error messages at all. No pano roof open. Service center Chicago never heard of it and cannot reproduce it. Anyone else got chimes. And no, there's not enough wind in the car to set one off.
