Don't know why...

I suggest you find a dealer to do this.
There are a number of items in the X3 known to NOT shut down when you turn off the ignition. For me - it is the stereo head unit. To test if this is your issue make sure you turn off the stereo manually before ignition off for a while. See how you go = especially if parking for a long time period.
If no difference then search this forum - there are a few causes for excess drain on the battery when the car is "supposed" to be off.
