Hi. I have got the same problem. Customer had adblue fault, drove the car to 0 km - impossible to start engine. Problem in is adblue ecu - it can not see that the adblue level in the tank even if tank is full. Dash has adblue light flashing and writes "Refill adblue to start engine". Any kind of RESET wont do the job as the car thinks the adblue level is 0 L and there is adblue level DTC active. Can the situation be solved by adblue OFF software? I have Autotuner files. Attached is OBD file.

Update. Found out that the adblue ecu was faulty and did not recognise the tank being full. Solved the problem by finding another good working adblue ecu with same part number 39023841, connected it to the car, put ON IGN and all the adblue messages on dash were automatically gone. Then flashed AdblueOFF sw to the engine ecu -- engine start -- no fault. Removed fuses F4 (7,5A IGN voltage to adblue ecu) , F9 (5A IGN voltage to adblue ecu), F10 (7,5A IGN voltage to NOx1, NOx2 and Particualte matter sensor), F24 (25A IGN voltage to adblue ecu) and connected back the old faulty adblue ecu just to have a working adblue ecu for future cases.
