If your rotor is developing a lip then you might be able to get a service department to replace the rotor as that's a tell tale sign that you're due for rotors.
Most if not all BMW service departments now have axle mounted lathe machines to turn the rotors. When customers go in needing new brakes, more often than not it's just new pads and they resurface the rotors. The axle mounted lathes don't require the tech to remove the rotors so it's far more cost effective for them to resurface the rotors than replace them. That is unless you're developing a lip at the rotor's edge. At which point you may need them replaced.
