Why does my Audi A7's engine make a rattling noise when accelerating?

I have noticed a strange rattling noise coming from my Audi A7's engine when I accelerate. It seems to go away once I reach a higher speed, but it's still concerning. What could be causing this and how can I fix it?

The rattling noise could be caused by a loose component in the engine, such as a heat shield or exhaust manifold. It's important to have this checked by a certified mechanic as it could indicate a larger issue with the engine. A simple fix may be to tighten the loose component, but further diagnosis may be needed.
