Why does my Audi A6 make a loud rattling noise when I accelerate?

I've noticed that whenever I press the gas pedal to accelerate in my Audi A6, there's a significant rattling sound coming from the engine. It's quite loud and concerning. What could be the cause of this and how can I address it?

The most likely cause of the rattling noise is a failing exhaust component, such as a loose or damaged muffler or catalytic converter. It's important to have this checked and repaired as soon as possible to avoid any further damage to your vehicle's exhaust system.

This could also be a result of a failing engine mount or transmission mount, which can cause excessive movement and vibrations in the engine. It's recommended to have a mechanic inspect and replace any worn out mounts.
