I coded my M40i to start in Sport Individual mode and yesterday I actually heard the valve open after running for 1-2 minutes. Heard a pop/click sound so I looked down and watched the exhaust cloud split from only right pipe to both. My guess is the valve is governed by driving mode. |

I leave it on the 1st setting as this opens the valves when you click sports mode Second setting which is balanced doesn't seem to open the exhaust valves when in sport mode so I guess it must use a computer to open the valves automatically The third setting reduced does reduce the sound in the car and I'm guessing it closes valves. |
