Exclamation FYI for X6 xDrive 50i drivers

I posted a thread in December about an SOS sytem failure on my fully loaded 50i that caused malfunctions to the stereo & blutetooth, disabling both. Mine was one of the fist such cases for this model, and it took a week for BMW service to diagnose and fix the problem, but I was happy to know that the issue was resolved. In the end, it was an ECU that needed to be replaced in the computer. My next electrical issue presented itself last Saturday while I was 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 listening to the radio, and for no more than 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.

Thanks for the info. My dealer didn't tell me about the ACC position, can you explain?

If you read the owner's manual, if you press the start/stop button without the breake pressed, you go into accessory mode.

If you hold the brake, and press the button, the car starts.

If you hold the button down for a couple seconds, the car turns off completely.

If you hold the button briefly, the engine stops, but AC is still on.

My IPOD is connected 24 hrs a day and I always listen to music for up to 30 minutes at a time (have to keep hitting the ignition button every 10-15 minutes to reset power) but I have never had a dead battery in 5 months.

My ipod is plugged in 7/24 ( except for updating) and I listen to it all the time but while driving. The "hit the button every 10-15 minutes to reset power" is this in the accessory mode that Chuck mentioned ?

Yes. It will only stay on in the accessory mode for a limited amount of time before it cuts power and you have to hit the button again

Hey leonelm3, you never posted any pics of your X6 on those 22" wheels... at least I don't remember having seen any...

Do you have any to share with us? I'm curious to see what that looks like. Also, what rubber do you have mounted on them and how is the ride compared to the stock 20"?

Also, what 'Extensive Performance & Custom upgrades' did you do to the X6 if you don't mind me asking?
