Why is my Audi A6 making a rattling noise?

Recently, my Audi A6 has started making a strange rattling noise while driving. What could be causing this and how can I fix it?

This rattling noise could be caused by a loose exhaust pipe or a problem with the suspension. It's important to have a mechanic check it out as soon as possible to avoid further damage.

Check under the hood to make sure all of the engine components are secure and there are no loose bolts or parts. It's also a good idea to have the catalytic converter checked.
