The coolant cap isn't air tight. There's always going to be a small leak over time. Depending on driving conditions (assuming lots of stop and go or your racing) coolant will "leak" out. It's normal. Be glad your BMW tells you that you are low and all you have to do is buy the 50/50 solution and put a little bit in next time yourself.
