hi i have a ercedes w221 S350 and make dpf and adblue off no mil on display , no dtc the car looks good but when you push the ac pedal full throttle for max power after some time 5-10 minutes the car block an enter in limp no dtc nothing. When i see in the live data the nox sensor is measuring nox concentration my question is : is normal that nox sensor measuring in the ecu because scr_module is disconnected can this make problem or the nox is better to stay off ???

In FULL SCR OFF you need to disconnect the SCR unit and NOX sensor.
