Well THAT was odd... (E82 factory stereo content)
Out running a few errands this morning. In and out of the car a bunch, so I left the stereo on (automatically shuts off when I shut down, comes back on when I restart the car, as usual). I come back the car after several such cycles and hear a loud buzzing coming from the rear of the cabin. Check in the trunk and underneath to determine it's definitely loudest inside the cabin. Stereo on, stereo off, doesn't change it. Ignition cycled doesn't change it. Nothing seems to affect it. Drive home annoyed with the buzzing in my ears....
Get home, decide to start troubleshooting. Before pulling the fuse I figure I will try to isolate the source. I adjust the balance full left and as I hit +10, the stereo display cuts off and the noise goes away. Cycle the stereo - now everything is fine. No buzzing, all speakers normal. Hmmmm.... Any thoughts on what just happened here? 2009 128i, standard stereo with factory satellite tuner (which was in use when the problem occurred). I hate intermittent electrical problems with a passion, so any suggestions on how to squash this would be most appreciated. |

That used to happen to mine too. A good bash on the dash with my hand would get rid of it for awhile. I finally removed the unit to clean\inspect the connections and it hasn't done it since...
