i posted last friday after finding my car dead in the garage...(was not used for 4 days....05 545...3 months old...) BMW assist came to jump the car...YES and it made a bunch of lights stay on on the dash...active steering and seatblet and airbag....active steering went away.....
took the car in this AM to dealer...they called and said it was ready....
he claims that it's my CELL PHONE CHARGER....that i leave plugged into the charger in the back seat...(the phone is not plugged in when i leave the car AND the light on the charger is not on...) but he "claims" that by leaving it plugged it does not allow the car to "go to sleep" ....it sounds "logical" but i am SOOO skeptical that the charger was the scapegoat.......anyone have this issue...

There is actually a Service Measure out on it, Dated April 2005
Here it is
Subject
Dead Battery caused by MPM
Complaint
The vehicle had a dead battery.
When carrying out energy diagnostics, the MPM (Micro power module) was identified as a possible cause.
Vehicles affected: E60/E61 (5 Series), E63/E64 (6 Series) produced up to September 2005.
Cause
Accessory plugged into the cigar lighter / power supply causes a back-feed of voltage into the vehicle electrical system when the ignition is switched off. This causes the MPM to stay awake, and the vehicle battery to discharge.
Measure
In case of customer complaint, verify that the customer uses the power supply for an accessory with an internal battery (cell phone with charger, MP3 player, radio equipment etc.) and that he leaves the accessory plugged in when the car is switched off.
Do not replace the MPM.
As a short-term fix, ask that the customer does not leave the accessory plugged in when the car is switched off. A programming solution is being developed and will be included in a future CIP version.

I've had it happen in my last two cars - the green charger light stayed lit when the car was off. Did it too often and whammo - dead battery. I don't leave chargers plugged in anymore.

Does'nt make that much sense, a little phone plug causes that much trouble. I pluged my phone in my other vehicles and left them on plus having aftermarket alarms and still not killing the battery for days.

Its amazing how many computers are in the car, and how they talk to each other
But if they dont go to "sleep" they drain the battery

My wife leaves her Nextel charger plugged in to the front receptacle all the time on her 03 X5, no problems to date.

[/quote]I assume this means the device needs to be plugged in as well, not just the power cord. I always leave my V1 power cord plugged in but take the device out and have never had an issue with the battery.

The V1 doesn't have it's own battery inside.

kscarrol you understood correct......i NEVER leave the actual phone plugged in....when i leave the car, JUST the phone charger......you are correct in your confusion just as i am......i just don't understand how/why leaving a phone charger plugged into the outlet WITHOUT the phone plugged in is causing my car to "stay awake"......there is no power being drawn from the charger.......
i'm sure MANY of you leave a phone charger plugged into the outlet at all times (overnite, while parked at work etc)........
