Hi!
I made DPF off on EDC16C3 with the well known switch solution. All was ok but after some km DTC P0470 Exhaust gas press. sensor - circuit malfunction triggered and get limp mode. Delete DTC and again it's ok for some time. Tried with sensor connected or disconnected.
Differential pressure is 118 mbar and dpf saturation is 18% all the time

You have to check dif. pressure sensor. Differential pressure 118 mbar mean sensor is disconnected.Check wiring and if ok try to change sensor itself. After you solved problem with sensor all will be ok.
Good luck.

Maybe need good solution instead of replacing all sensors and finnaly replacing new dpf filter?

I said to check diff press. sensor and that is all, it is one sensor. It is not such big job. I had same problem before. Many soft solution did not help me. Finally I solved problem with sensor and after that all was ok with dpf. Actual value 118 mbr is value when sensor is disconnected.Off course he need to remove dpf and make well known switch solution. So good diff. pressure sensor + remove dpf + switch solution= no problem with dpf anymore.

Even if I reconnect sensor, I will get this error after some time. If sensor is connected, then it's works ok, measure pressure well.

connected / disconnected will have no difference
