Why does my Audi 80 make a high-pitched whining noise when I accelerate?

Whenever I accelerate in my Audi 80, I hear a high-pitched whining noise that lasts for a few seconds. This noise only occurs during acceleration and not at any other time. What could be causing this and how can I fix it?

It sounds like your serpentine belt may be worn or loose. It's important to have this checked and replaced if necessary, as a worn serpentine belt can cause damage to other components in your car. I recommend taking it to a trusted mechanic.
