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

I recently noticed that my Audi A7's engine makes a rattling noise when I accelerate, but it stops as soon as I reach a constant speed. What could be causing this issue and should I be concerned?

It is likely that the rattling noise is coming from a loose or worn out belt in your engine. It is important to get this checked out by a mechanic as soon as possible to avoid further damage to your engine.

The rattling noise could also be caused by a faulty exhaust system. It is recommended to have a professional inspect your exhaust system and make any necessary repairs.

Another possible cause of the rattling noise is a loose heat shield. This is typically an easy fix and can be done by a mechanic or even yourself if you have the right tools. Just make sure to address the issue soon to prevent any possible damage to your car's components.
