ditto - I think all X5 owners have experienced this - the X5 is an electrical hog - I try to miminize this by making sure everything (heater/ac, radio, lights, radar detector, wipers, etc) is turned off before turning off the key - even then 5 years and it's replaced - cold kills batteries and you have experienced a cold winter with an old battery - try what MD said - it takes a few minutes for the OBC (onboard computer) to reset evereything, usually

a good rule of thumb, no matter what your car is, over 4yrs, with winter approaching, replace - granted, a heated garage helps, but having lived in NJ most of my life, most of you don't remember when winter was WINTER

Oh, you have also had your antifreeze checked or replaced by now..., right? if you have a V8, there are two 30mm coolant hoses behind the engine that should be ready to be replaced also
