Check engine lights that are stored for Mass Air Flow sensor codes that occur on both banks are in relation to a hole in the bottom of the intake air boxes. From my understanding from the factory some M5/M6's came with a hole in the bottom of the air box, that was a mistake and requires a block off plate. Its a simple fix and I hear has resolved all issues present.
