Rough/possible misfires on idle on S55

[KonnerF]

Hey guys, so I've been trying to pin point a current problem with my 2017 m4.

Sometimes when I start the car it almost stalls out. The RPM would drop really low and then bounce back up to normal. I'm going to put some videos down below to make it easier to see. Possible misfires on idle without any codes? I've ran codes and there was none. There is a hose coming from the intakes to somewhere I have no clue. The clip snapped off and I'm assuming (not sure) if it's leaking from there. I don't know if this would even cause the issue I'm having. I just got new spark plugs put in about ~3k miles or so.
I've heard to check the MAF sensors. Do a smoke test to see if there's a possible leak somewhere else, and etc.

haven’t had time to go over it. only thing i’ve done is run codes and none popped up. is it possible to have a bad coil pack without codes ?

It happen to me recently was having a misfire with out a code but I notice the inconcistent jumps in the idle from time to time and it was a coil pack in the 6th cylinder
