Engine rattle

[DAZA24_]

Hello, I recently bought a used 2024 Audi RS3 with low miles on, 6000 miles. However starting it in my garage with the engine completely cold pointed out a strange rattle noise, and I don’t really know where it comes from. I’ll leave here a link for a YouTube video that has my exact problem: click here. There also other threads on other forums with my problem, some says that it’s the timing chain slacking, but I don’t really know.

Sounds like it could be either the timing chain tensioner or exhaust valve. But it does sound pretty cool.
