I am still new to bmw so not sure if this sound is normal or not. I hear it when I start the car after it sits for a while. The whine sound goes away after minutes or two. Also the brake vacuum pump is making a noise also towards the end of the video. I just got it replaced and the noise is back I will take it back to the dealer but need to know if the other noise is normal.
Thank you.
Thank you.
