Why does my Audi A5's engine make a whining noise during acceleration?

I've noticed that my Audi A5's engine makes a high-pitched whining noise when I accelerate. It's not very loud, but I'm concerned it might indicate a problem. Can anyone explain why this is happening?

The whining noise during acceleration could be caused by a failing or worn out belt in your engine. It's important to have this checked and replaced if necessary, as a broken belt can lead to engine damage.

Another possible cause of the whining noise could be a faulty power steering pump. This can also be accompanied by difficulty steering or a whining noise when turning the steering wheel. Have a mechanic check this out for you.
