Why is my Audi A6 producing a strange rattling sound while idling?

I recently noticed that my Audi A6 is making a strange rattling noise while idling. It seems to go away once I start driving, but it's still concerning. Any ideas what could be causing this and how I can fix it?

Hi Rachel, it's always best to get any strange noises checked out by a professional mechanic. It could be anything from a loose component to a more serious issue. I suggest taking your Audi A6 to a trusted mechanic for a diagnostic test.

I had a similar issue with my Audi A6 and it turned out to be a loose heat shield. It's a common problem in this model. I recommend having your mechanic inspect the heat shield and tighten any bolts if necessary.

My Audi A6 had a similar issue and it was due to a problem with the exhaust system. Make sure to have your mechanic check the exhaust system for any leaks or damage.
