Why is my Audi A7's engine making unusual noises?

I have noticed that my Audi A7's engine is making strange noises while running. It seems to be coming from the front of the car. What could be causing this and how can I fix it?

It's possible that your Audi A7's engine is low on oil, which can cause unusual noises. Check the oil level and add more if needed.

Another potential cause could be a worn out serpentine belt. This can cause squealing or whining noises. Have a mechanic check the belt and replace if necessary.
