EPC light + fail code 14313

[Justdb]

Greetings!
Yesterday my epc turned on and my car felt like it drove on 3 cylinders.
Im abit confused here, since I never saw this kinda of fail before. So I’ve a few questions, after researching abit into it.

I've ofc used vcds, and found this fail (picture attached)

My first question is; Which on the picture I have pulled into aswell, is it who makes the issue here?
A dealer told me one thing, a close irl friend told me another thing.

And are these even safe to change urself? I've quiet experience of doing things, but I've never tried this before,
so I better reach a hand out. Maybe someone know, and have tried this before.

I've made 6 rings, of what I think it is. The 4 rings close to the coils, is what I think is right at most, since there is 4.
2 on the air side, and 2 on the exhaust side. And since it cylinder 3, B - It should be (on the picture bottom left). The engine is ofc turned around, compared how its fit in the air,
but get the point. :P

I will today try to take off the power for that actuator, and see if that changes anything, before doing anything else.

My first question is what is it on?
Audi?
Year?
Model?
Engine?

Cant help if no one knows what the car is...

My second question is did you read the VCDS screen?

"Exhaust cam adjuster B cylinder #3"

The VCDS is telling you exactly what the problem is!
