Hi,
Recently purchased a brand new 4 series (2021). About a week ago, I started noticing a strange whining noise coming from the inside of the car when the A/C is on and the Start/Stop function is operating. Whining normally happens when I come to a stop or accelerating from the stop (basically when the A/C kicks).
I've made a recording and you should be able to hear the noise at 0.26 and 0.34: New Recording 2.m4a
Went to a dealership, but after having the car for 2 weeks and taking the dashboard out, they didn’t solve the issue.
Also found another perso with the same issue on YouTube: https://www.youtube.com/watch?v=6ADqXQmHee0&t=120s
Does anyone have the same issue or has a solution? Would very much appreciate that.
