Mike Miller recommends Redline MTL. With that being said, you should use the factory fill. If anything happens to your transmission under warranty and BMW does an oil analysis, they will see that the oil was not "factory fill" and will probably deny a warranty claim. It's definitely a good idea to change it, but I would definitely use the factory fill while the car is still under warranty.
I believe you need a little under 3 liters. This link should help you...
