Engine bay knocking sound 2016 Opel Corsa SRI

[smileyhailey]

I've been experiencing a loud knocking noise from my 2016 Opel Corsa SRI after the engine warms up and I come to a stop. The sound is only noticeable from inside the car, and I haven't been able to pinpoint the source, even after checking the engine bay. Some have suggested it might be the fan, but I've noticed the sound even when the fan isn't running. I came across a YouTube video of a fuel line rattle that sounds similar, but I'm not sure if that's the issue.

Does anyone have any ideas about what might be causing this noise?

It could be a loose component, like a heat shield or something near the exhaust system, causing a rattle when the engine cools down. It could also be related to the fuel lines or an issue with the idle..do a thorough check
