Strange engine sound at 2000 rpm

Hi all, I have a 2017 BMW X4 with 170000 km on it and I noticed that when driving around 2000 rpm the engine makes a strange, rather high pitched sound. Otherwise the car is running normally. Do you know what could be the cause of this sound? Thanks for any advice or experience!

Check if the serpentine belt is worn or loose, as it can cause a high-pitched noise. Inspect it for any visible wear or damage. Let me know if this resolves the issue or if you need further assistance.
