This is from the m3, when doing about 70 and accelerating i hear a slight high pitched noise.
You can hear it at 6 second mark on this 11 second recording. Can someone have a listen and let me know if i should worry. I noticed it fairly recently, i i think it is new to the car. Engine rebrebu about 8k miles ago and otherwise running fine.
