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

I recently noticed that my Audi A4's engine is making a strange noise while driving. It's a high-pitched whining sound that seems to get louder with acceleration. Is this something I should be concerned about?

It's important to have any unusual noises coming from your engine checked out by a mechanic as soon as possible. It could be a sign of a serious issue.

Have you checked your engine oil level recently? Low oil levels can cause unusual noises in the engine. Make sure to top up if needed.

It's possible that there is a problem with your exhaust system. Have a professional inspect it to make sure everything is working properly.
