Got a new 2021 M3 ST+ 2 weeks ago.
On the highway, speeds between 78-83 mph, I notice a faint whistle/flute like sound.
Thought it was my music at first, but have since been able to replicate this “flute like” sound many times going over 80 mph.
What in the hell is going on? What do I even tell the service center?
