in the engine ecu there are no errors eobd P or U. the only error is in the SCR module N118. fixed with adblue off

sorry I did not understand. maybe it's a translation problem ... i edited the file, adblue off. With the adblue file off, you can clear the diagnosed dtc and it won't take it anymore. I didn't unplug anything.

I get it! by now I have delivered the car. If I disconnect the scr module, does it not take some communication error in the engine ecu?
