Why does the Audi A7 engine make a rattling noise when accelerating?

I've noticed a strange rattling noise coming from my Audi A7's engine when I accelerate. It doesn't seem to affect performance, but it's definitely concerning. Any ideas on what could be causing this and how to fix it?

The rattling noise may be caused by a loose heat shield or exhaust component. It's best to have a mechanic check it out to ensure proper functioning of the engine.

The noise may be due to a malfunctioning camshaft position sensor. I'd suggest getting it checked and replaced if necessary.
