N54 Intense Engine Rattle

So yesterday I noticed my car starting making this rattling noise when I startup the car and doesn't stop until I close the car. When I first bought the car I had a wastegate rattle, but this is 10x more intense. The rattle comes from the injector side of the engine near the 3rd or 4th one.

I know it's not alot of info, but the rattle looks distinctive from all the other noises that could happen in that engine bay.

Also when I was looking from where it was coming today, I noticed a little knocking sound coming from near the thottle body after 2-3 minutes of idling.

I have no check engine light and the only thing I recently changed was the intercooler and tuned it mhd stage 1+ after that.

I'll put a link for the videos.

Thanks for the help and sorry if I'm not clear enough, I'll go to my garage soon enough to get a professional opinion. Have a great day!
