Exhaust valve in sport mode - Closed in Drive, open in park?
I have a couple threads with issues after getting my car back from the service center, mainly with iDrive, but this one is with the exhaust valve in sport mode.
I noticed what sounded like the valve closing when putting my car in drive while in sport mode. I made a video below to test the the theory, and sure enough the valve is opening while in park, then closing when put into drive. https://streamable.com/lgm147 I can't recall this ever happening before when I bought the car, so I'm curious if this is normal or not. Does the valve open at a certain RPM similar to comfort mode? The exhaust note is also quieter and pops less. |

I believe yes. It closes even in sport mode and opens up only after a certain RPM when you’re driving it.
