Exhaust valve?
Hello this is my first thready in this forum, pardon my english.
Does anyone know in what condition does the exhaust valve close/open? I notice even at idle my exhaust valve is open. I did bring this question to local BMW dealership and it's also open at idle on the other M2. We played with comfort/sport/sport+ nothing changes. Drove the car so it reach normal temp the valve still open. We even open the valve actuator to see if it's rotating, which isn't. If the valve remains open why BMW put the valve in the first place?
