Why does my Audi A7's engine rattle when I accelerate?

I just bought a new Audi A7 and I noticed that the engine makes a rattling noise when I press down on the gas pedal. Is this normal or should I be concerned?

It is not normal for an engine to make a rattling noise when accelerating. It could be a sign of an underlying mechanical issue or lack of proper maintenance.

I have had the same issue with my Audi A7 and after getting it checked by a mechanic, they said it was due to a faulty valve in the exhaust system. It should be an easy fix.

The rattling noise could also be caused by a loose or worn out belt in the engine. It is important to have it checked and replaced if necessary as it could lead to bigger problems down the line.
