Why is the Audi A4 making a strange sound?

I recently bought an Audi A4 and noticed that it's making a weird sound whenever I accelerate. It's not too loud, but it's definitely noticeable. What could be causing this and how can I fix it?

It's possible that the sound is coming from your exhaust system. You may want to get it checked by a mechanic to see if there's any damage or if it just needs to be tightened.

Have you checked your engine oil? Low levels of oil can cause unusual engine noises. Make sure to top up if necessary.
