Ok, so this morning we to use the 2007 X5 and it just flickered some what crazily (all the lights on the dash, and such)... No start. So we tried it again and this time it did it again, but a bit less "violently".. 3rd time the wiper came on "slow motion" and the car died.

My question is this... Doesn't the X5 have a feature that protects the battery from drain should someone leave a light on inside? Or could my kid of wife have left a light on and killed our battery?

Anyone know? thanks

Sam
