Why does my Audi A5 produce a rattling noise when I accelerate?

I've noticed that my Audi A5 makes a rattling noise when I accelerate from a stop. It seems to be coming from the front of the car. What could be causing this issue and how can I fix it?

The most likely cause of this noise is a loose heat shield. These shields are meant to protect your car's undercarriage from excessive heat, but they can become loose over time and rattle against the exhaust system. You can fix this by either tightening or replacing the shield.
