Hi, I was brought to the workshop this type with 112000km year 2019 engine code 55280444, with Adblue failure and Engine failure light on. In engine ecu diagnosis I find error U010E (SCR ECU communication with engine ECU - communication error), while from the metering system I get the following error codes:

P13F3 : Adblue pressure sensor absent or invalid signal
P2BAF : NOX emergency system
P20EA: Adblue control unit main relay voltage supply disconnection too early

Removing the errors leaves P2BAF while P13F3 returns

I know there is a specific resetting procedure for P2BAF, but the other error I don't know whether to refer to the ECU or the tank...

For this error, a diagnostic check list to follow?

Thanks in advance!
