WHAT SHOULD I LOOK AT FIRST


You need to look at the door lock actuators, I'm guessing 1 is operating but staying on when locked and draining the battery. Try manually locking the doors and see what happens. It may come down to removing the door trims and disconnecting each lock in turn, don't forget the boot lock, until you find the culprit. Its possible you may hear the lock solenoid humming or buzzing or feels warm as its trying to lock the door unsuccessfully.

Seems highly unlikely. I can imagine a possibility for a drain that might discharge he battery when the car is off, but your description suggests that you have determined that it is not charging rather than draining when turned off. You can rule out a drain in the seat heater by removing the fuse for the seat heater and see if the problem persists.
The software upgrade answer sounds Bogus.
There are a lot of good German car specialty shops out there. Check the Mechanics Files on the CarTalk web page or hook up with your local BMW owner's club, and find a good independent shop.

it seems like something is draining your battery while the car sits overnight. causing the battery to get weaker and weaker putting stress on the alternator making it fail prematurely. the dealership will do a paracidic drain test where they'll find out what is draining your battery while your car sits overnight. it could be a bad module somewhere that's staying on when it shouldn't be.

BMW X5 Battery Drain.


hello theringbar, I would recommend checking the a/c blower resistor. it is an electronic final stage and can kill the battery overnight. the final stage is located on the passenger side at the back of the a/c heater box.
