First thing you should be asking yourself is how old is the battery? If original, it's time for a new one (I replace every 5 years, rather than waiting for it to give out at an inopportune time) Winter usually finishes off weak, old batteries. My 2001 X5 was a 12/00 build. So when I bought it used 7/01, I replaced the battery before winter set in. Just one of those normal (any) car maintenance things.
