Why does my Audi A4's engine make a loud whistling noise?

Recently, my Audi A4's engine has started making a loud whistling noise whenever I accelerate. It seems to get louder as the car gets faster. Can anyone provide insight into what might be causing this?

Based on your description, it sounds like your engine's serpentine belt may be failing or slipping. This can cause a whistling noise, especially at higher speeds. I recommend taking your car to a trusted mechanic as soon as possible to have it inspected and potentially replaced.

I had the same issue with my Audi A4. It turned out to be a faulty turbocharger. I suggest taking your car to a dealership or a specialized mechanic for proper diagnosis and repair.
