Engine a bit jerky, cylinder misfires and strange sound - Anyone here that knows what it could be?

Hello, theres something that is concerning with my Skoda octavia 2015 1.2 TSI. I have a CJZA engine. This is my VIN number: TMBJB9NE0F0039056.

When I drive it can sometimes feel abit uneven and it feels like it jerks a little. This is most noticable when i drive on low RPM, around 1.2k - 1.5k. I got a OBD II reader and it appears that I have some cylinders misfiring. I pulled up the live datastream and looked at misfires per 1000 revolutions per cylinder and this is what i found out:

At 2k+ RPM (Amount of misfires per 1000 rev.)

Cylinder 1: Hardly any misfires, maybe up to 1 some times.

Cylinder 2: 4-5

Cylinder 3: 2-3

Cylinder 4: maybe up towards 10.

At 1.2-1.5k RPM (Amount of misfires per 1000. rev.)

Cylinder 1: Similar

Cylinder 2: 6-7

Cylinder 3: similar

Cylinder 4: The worst ive seen is up to 26, but usually only goes up to around 10-15.

Theres no engine light in the dashboard, and the car runs mostly pretty well except this jerking. I recently got all the spark-plugs changed when i had it in the shop for a service (oil change and regular stuff).

I tried switching places of the coils to see if the problem moves, but its on the same cylinders. When the car is idling it is even and nice, and i can see no misfires. I have used STP injector cleaner run through an entire tank of gasoline with that in it, that didnt change anything. When i am crusing evenly in the 60-80 km/h range i hardly notice anything, and hardly get any misfire counters.

Theres also this strange rythmic sound on the left side of the engine, i have attached a video where you can hear it. This sound is not always there, some times when i pop the hood and listen i cant hear it.

If you need any more information to help me diagnose this problem, feel free to ask my any clarifying questions and i will answer to the best of my ability, I am not very experienced with cars but I am trying to learn 😊

I would like to thank anyone in advance for any help i get 🙏
