Why is my Audi A6 making a loud, rattling noise while driving?

I recently purchased a used 2016 Audi A6 and have noticed a loud, rattling noise coming from the engine while driving at high speeds. It seems to be worse when going uphill or accelerating. What could be causing this issue and how can I fix it?

It is likely that your exhaust system is loose or damaged. This can cause loud rattling noises while driving. I recommend taking your car to a trusted mechanic to have it inspected and repaired as soon as possible.
