New DPF sensor and dpf issues

I am having some issues with the dpf and I am currently trying to fix it. But i have come now to a point where i have no idea how to move forward. I have not found a post regarding it.

Current status and history of stuff I did:
-Fixed the exhaust clamp between cat and dpf because previous owner bodged it.
-fitted new hose clamps on the dpf sensor hose because they were missing.
-installed new dpf sensor from hjs
-tested the hose for leaks
-blown through the two sensor pipe on the dpf

Issues i am having is that my icarsoft tool is telling me P244A and if i read the value of the Differential pressure Bank1 it only ready 0,03 kpa. It does not move even when driving. My thought is that it should at least fluctuated a bit even if there would be a exhaust leak i am not aware of.
My next idea was that it got to be something with the wiring. So i tested it via a crude method which is not really 100% conclusive but it gives me a maybe a clue. So I just unplugged the sensor and now the sensor reads 129 kpa. Which leads me to believe that the wiring is ok.
Also the dpf says it is full but even with that problem I should see some corect values with the icarsoft,right?

Does the new sesnor need some sort of adaptation?
I appriciate every help I can get

Thanks in advance.

Thank you. Do you know which tool is able to do that? Because on my icarsoft lr 2.0 i am not able to find it.
So even tho it is a Evoque and not a Disco3 it is the same issue o.O , interesting.

Thanks for the reply.
