The sensor has dies completely now, no readings at all , stays at 0 mBar. No more DPF error P2002, just P2453 for the sensor. This does not throw up error light and no limp mode / reduction in power. So in a way it's good news, I do not need to rush into changing sensor and could send the wrong ones back and get correct.
I understand if the sensor is not working ECU will start regeneration based on the mileage since last regen instead of readings from the sensor. It's not ideal long term but does not stop using car to full potential in the meantime. The problem is sensor could start partially working again and give the wrong readings causing limp mode. I will have a look under car today anyway and see if I still want to try to change it today or maybe unplug it for now if it's possible with less dismantling and wait with change until I get the right ones.
