Why does my Audi A4 make a rattling noise when I accelerate?

I've noticed a rattling sound when I press on the gas pedal in my Audi A4. What could be causing this and how can I fix it?

The most likely cause of this noise is a loose heat shield near the exhaust. I recommend taking your car to a mechanic to have it checked and tightened if necessary.

It could also be a problem with the engine mounts. These can sometimes wear out and cause rattling noises when accelerating. Have a mechanic inspect them and replace if needed.
