Why does my Audi A1's engine make a knocking noise at high speeds?

I recently noticed that my Audi A1's engine makes a knocking noise when I accelerate to higher speeds. It doesn't seem to affect the performance, but I'm concerned it could be a sign of a bigger issue. What could be causing this?

This could be due to a few different reasons. Firstly, it could be a sign of low oil levels. Check your oil level and top up if necessary. Secondly, it could be a problem with your fuel filter. If it's clogged, it can cause the engine to make knocking noises. Lastly, it could be an issue with your spark plugs. If they're worn out, they can cause knocking noises. I recommend getting your car checked by a mechanic to diagnose and fix the issue.
