when you start the car up initially both exhaust flaps will be open. after a minute or two you will hear the left exhaust flap close.
it will only open again i believe when you reeally open up the throttle |

There are a lot of variables and also depending on your selected mode and the operating condition, the computer decides when to use only one or both...
Dont you worry, everything is normal. Just enjoy your car. And yes you are too sensitive, Welcome and Congrats. PS: this question has been asked so many times already, we recognize all BMW noobs by it. |

Can we make a sticky for this question. There is a new thread about it literally every other day.

Don't worry,This is the 435I GRAN COUPE unique valve logic.435i GRAN COUPE either "sport" or "sport plus" , place the valve is closed,When you keep moving state, and the engine speed to break through 2700, the valve opens.

sigh, BMWs had the exhaust valve for 13 years now... people still don't know. Can you just look at the 5th sticky note in this forum ?
