Why is my Audi A4 making a whining noise during acceleration?

Every time I press down on the gas pedal, my Audi A4 makes a loud whining noise. It seems to be coming from the engine compartment. What could be causing this and how can I fix it?

It's possible that your power steering pump is failing. This can cause a whining noise during acceleration, as the pump struggles to keep up with the increased power demands. You will need to have the pump replaced to fix this issue.

Another possible cause could be a loose or damaged serpentine belt. If the belt is not providing enough tension or is worn out, it can produce a whining noise during acceleration. You should have the belt inspected and replaced if needed.
