I've had my 540i for five years now. For the last two years I've been
hearing an intermittent "popping" sound from the left side of the dash. It
sounds distinctly electrical, but there are no symptoms or problems with any
of the car's electrical. I've had it in the shop twice, and they claim that
they either can't hear the sound, or they say they can't see any evidence of
problems when they got into the dash to investigate (between you and me - I

Has anyone else experienced this?
It's not causing a problem with the car, but it's driving me absolutely
batty. I've got very sensitive ears, and I don't think I should be hearing
this sort of sound from the dash of a $61,000 luxury car.
BTW: It's not associated with the audio system, lights, turn signals, engine
speed, or any other obvious sources. The sound happens randomly every 3-7
seconds, whether idling or driving at 70 mph. Hot or cold weather, rain or
shine. IT'S DRIVING ME CRAZY!!!
