Why is my Audi A7 making a loud rattling noise?

I recently noticed that my Audi A7 has been making a loud rattling noise, especially when I accelerate. What could be causing this and how can I fix it?

It's possible that your engine is experiencing detonation, which can cause a rattling noise. I suggest taking your car to a mechanic to get it checked out.

Another potential cause could be a loose heat shield or exhaust component. I recommend having a technician inspect these parts to determine the source of the noise.
