Scania R420 2011 - too high emissions, power reduction EMS errors

Hello everyone, I have a problem with Skania - at the beginning there was a message "too high emissions and a reduction in power in 50 hours.
This message would light up and go out, sometimes the amount of time remaining until power reduction would decrease, sometimes the message would expire and then light up and the countdown would start from 50 hours. This situation could be repeated several times in a few minutes or this message did not appear at all .
As if something (electric wire) once had a contact, once not. Error after connection computer - break in the NoX sensor - canceled. After about 1500 km, it appeared again and immediately the power reduction occurred.
At that time, Adblue was downloading - it was working, at the moment it doesn't download Adblue, it doesn't heat (cold wires)
The active errors read currently are: EMS 4108, 11182, 4106, 4124, 8263, 11176 and GMS 2324.
I will add that for over two months the outside temperature that appears to me is overstated by about 10-12 degrees C.
Anyone have any idea about this situation?
Thank you in advance for any help.

Hello, you have to replace the nox sensor

The first thought was like that.
In fact, when you reach Nox, you can see one path burned - the plug is also charred.
Also the fuse from the "balloon" was burned - therefore no Adblue level indication and no heating of the Adblue tank.
The question arises as to the cause of this condition?
