2009 Golf 6 1.4 TSI 122hp engine rattle diagnosis

[Kamsa12]

Hey guys, I'm assuming the lot of you will already know or have seen plenty about this and will be able to help me correctly diagnose this. I am expecting it to be the timing chain, but am not 100% sure and am worried it might be worse than that.

I bought a Golf 6, 1.4tsi 122 hp with 113,000kms on the clock. The car is in great shape aside from what I suspect is as you expect, a timing chain rattle.
Now, normally I would just drive my car to a garage for the diagnosis, however here in The Netherlands, garages are often massively overbooked and I won't get a slot until August the 20th, as ridiculous as that sounds. I also need the car a lot earlier than that.

I have recorded several videos for the purpose of diagnosing said issue.

The noise is present on idle and when accelerating, not when decelerating. Don't know if that means anything.

If there are any tests or things I can do to further diagnose the issue myself on hand, please let me know and I'll try them pretty much right away.
