Why is my Audi A3 making a strange noise while driving?

I recently purchased a used Audi A3 and have noticed a strange noise when I'm driving at high speeds. It sounds like a rattling or grinding noise but I'm not sure what could be causing it. Any advice on how to fix this issue?

It's possible that the noise is coming from your exhaust system. You may want to check for any loose or damaged parts that may be causing the noise.

Another possibility is that your tires may be worn or improperly inflated. Make sure to check your tire pressure and tread depth, and consider getting them replaced if necessary.
