Recently purchased an '07 530i e60. Love the car with one exception. Is there a way to turn down the volume on the seat belt chime? I recently drove an '09 3 series and it had a volume setting for this. Does dealer service have a way to adjust this volume, as it's really way too loud!? My dealer says they can't do this, however, I know there are many changes that can be made through programming. Any help would be appreciated.
