Why does my Audi A5's engine make a rattling noise when I accelerate?

I noticed that whenever I push the gas pedal down to accelerate, there is a distinct rattling noise coming from the engine. What could be causing this issue and what steps should I take to fix it?

The rattling noise while accelerating could be due to several reasons, such as loose engine mounts, worn out bearings, or a damaged exhaust system. It is best to get your car inspected by a professional mechanic to accurately diagnose and fix the issue.

I had a similar experience with my Audi A5 and it turned out to be a faulty catalytic converter. This could be a possible cause for the rattling noise. It is important to get it checked and replaced if needed, as it can cause more damage to the engine if left ignored.
