Hello, I just received my 2024 M2 and I noticed that every time I start the car, the exhaust button turns ON (light is on). Is there a way to have the button default off? I know I can program the M1/M2 buttons on steering wheel to turn off that feature, but in Road mode, it always turns on.

This happens to mine too, the exhaust button is lit to have the flap somewhat open (not M Preset) and auto start-stop off by default every time I get in.

I’ve tried everything but the exhaust button always turns on when I start the car. I would like it quiet in the morning and have that default off. Nothing seems to work. I did notice I can turn off the exhaust button permanently through the Bimmer Code software, but I don’t want it off permanently. I guess I just need to turn it off manually every time I start the car.

Thanks. I appreciate the answer.

you are aware that this Button does nothing to the exhaustflaps.. it´s only more "exhaust"-Sound from the speakers...

I thought people had established in sport and sport+ that it does effect the flap. Given winter temps and breaking period I have not cared to try to verify myself.

An option is the Dahler exhaust flap controller.. not only gives much more control over the actual function (like open really means open) but also has a memory function too. I will have an DIY up for it soon.

During our testing on the G82, we observed that activating Sport or Sport+ modes enhances the exhaust note with additional pops and burbles, particularly noticeable in the latter mode.

Additionally, the sound volume increases when the valves open after pressing the sound/exhaust button.

We specifically made a video to showcase how valves act on the stock exhaust (Min 5:24) with different modes and sound button activation. Hopefully, this can answer some of the questions.
