Look up Z4 sound generator on youtube.

Edit: 135i also have a sound generator, according to ETK. Dang. Someone be the guinea pig, pls. https://www.ecstuning.com/b-genuine-...r/13717575658/

I was under the impression modern BMWs played engine sounds through the speakers? Here is the article where I read about this:

Anyone know if 1ers have the "symposer"? A quick google search shows the 2 series has it, and it changes depending on what mode the car is in, i.e. Sport mode is louder.

I didn't realize we had a mechanical piece piping sounds into the cabin, also.

I can't find it right now, but I saw a video where someone replaced the sound file with a Lamborghini sound in a more pedestrian car. Pretty funny.
