They told me that this noise is probably caused by the half dimples on the rotors as the the M models come with full dimple rotors and the technician was actually upset that he could not fix this minor thing.
I am planning to write a letter to BMW urging them to spend some time investigating this as this is an embarrassment on their part and mine.

the F30's m perf brakes have also dimpple rotors and dont make that noise..
i think it has nothing to do with half or full drilled rotors
