Why is my Audi A6 sedan making a knocking noise?

I've noticed my Audi A6 sedan making a knocking noise under the hood, especially when I hit bumps or turn the steering wheel. What could be causing this issue?

It's important to have your car inspected by a professional mechanic to properly diagnose the issue. However, based on your description, it could be a problem with your suspension or steering components. These types of issues can become dangerous if not addressed.

I had the same issue with my Audi A6! It turned out to be a loose heat shield. I would recommend having your mechanic check the heat shield and tighten any loose bolts.
