Hi, my f31 made 2016 2.0d rwd started to make whistle noise from the rear of the car when i accelerate. U can hear it in my video... Harder i go on accseleration - louder it whistle. Anyone have any ideas what is wrong with my car? Car have done 270k, i have changed automatic transmision oil, rear diff oil and still receivining the same noise....

Normally when you hear whistles that increase under acceleration, you've got a leak in your exhaust.

Does it whistle at idle? Does it whistle when you're not moving, in neutral, and revving the engine?

No I can't hear whistle at idle or at any higher rpm, i can hear it only when i drive over 60 km/h and no matter in what gear, with traction control or without it. Same in sport, comfort or eco mode. When steering left or right at higher speed sound doesn't l goes away, so i think its not the wheel bearings... Thankfull for any thoughts
