If you currently have BMW coolant in there, I'd say just go down to your local BMW dealer and get some more.
To check or add coolant:
1) Locate your reservoir tank located at the lower left corner of your engine bay.
2) Take a cotton rag and unscrew the cap, you do not have to push down on it.
3) If the engine is cool, the floating stick should be floating at the very top. There is a small chart of the tank itself if you are unsure.
4) If everything looks fine then it might be because you have a bad sensor.
5) If it's really low then you might want to check for possible leaks.
**Important: Don't forget to dilute the coolant with 50% coolant and 50% distilled water**

You need to take your car in to find out where the coolant disappeared to. The stuff just doesn't go away in the volume you are talking about for a 2003 model till now.
Like Tom said, if you top it off and then it disappears again, you know you have a leak somewhere.
I would just take it in and have them check it out under warranty.
