As I'm now pretty confident of the conclusion, bought a new OE, not oem, battery, installed at stealer.

Cause of replacement:
Turned on HID fogs, but double-hit the switch, int lights came on, four way flashers blinking. Hit 4-way switch, then open close door to kill int lights. Hit fogs again, all seems well.

Next day (12 hours) battery totally dead. Stealer says prob with my DEPO AE's, surprise.

Install OE battery, no AE's 2 days, all is well.

Re-attached AE's last five days. all is well.

As stated many times here, wonky electronics? start with the battery. And feel free to verbally bash me, but if you can afford it? get the BMW OE stupidly expensive battery (replaced < 2 year old highly recommended Optoma).

Also, wife was giggly about how well the X performed in our goose-poop snowstorm last night. Apparently cars were sliding everywhere, she was 'on rails'. Nice.

EDIT: Stealer said battery tested Fine, told 'em to replace anyway (winter, been dead, going for ultimate safety)
