As OP said, Is my battery about to die?
...I didn't drive my car for a week and now requires clock resets every time I start it. Also, the keyless access entry balks, requires keyfob button push. Engine start is fine and no probs with radio presets tho prob stored in key each time.
Does it HAVE to be a BMW battery replacement? How about good ole Interstate, etc.?
