My next electrical issue presented itself last Saturday while washing my car and listening to playoff football on the Sirius radio with the engine off. The car went completley dead after 10 minutes, and every time I tried to start the engine, all the symbols on the dash display flashed quickly on and off, and the car started clicking constantly. I had to have it towed to BMW service, where they found I had drained the battery. This was a shock to me considering all I thougt I was doing was listenng to the radio, and it was for only 10 minutes. What I was told by the service department is that whenever you turn the power to the radio on, it also sends power to many other drivers that control climate, seats, iPod, cell phone, and etc., etc. etc. I don't claim to be a car expert, so I was curious, does this explanation sound reasonable?
I was disappointed to find that I won't be able to simply listen to games or music while washing my X6, but I guess that's the price you pay for all the other luxuries. I have a habit of leaving my iPod connected in the car for days a a time, and that too will drain battery, even if the car is off (This is what the dealer told me). Thoughts anyone?
I wash/dry mine and never had battery issues. Even played music at tailgate parties.

You do need to hit the button every 10 min, kind of annoying. I wish there was a bypass.

The thing to remember is make sure you are only in the ACC position and not powering all the dash lights, headlights, and starter. That will drain the battery for sure.
