Why does my Audi A2's engine make a rattling noise at high speeds?

I recently purchased a used Audi A2 and noticed that the engine starts making a rattling noise when I reach speeds above 60mph. It seems to be coming from the front of the car. Can anyone give me some insight into why this might be happening?

It's possible that the rattling noise is coming from the engine's timing chain. It may be worn out or loose, causing it to make noise at higher speeds. I recommend taking it to a mechanic to have it checked and possibly replaced.
