Hey, i would like to ask for help. I have a problem with losing fuel adaptation. I use the "56" soft on the M54B30. After uploading the new software and connecting the engine driver everything is ok but after a while of running the engine for unknown reasons a "0" error appears and the fuel adaptations are set to the maximum negative values. After this incident, they can not be removed at all, I tried in different ways, I changed the ECU and every one after that there is a "0" error and the adaptations go to negative. The flow meter was changed and the lambda probes were physically removed and the ECU was removed
The problem lies in the engine or electrical harness. Only why can not I remove the adaptation of any program? And what could be the error "0" in MS43 ver. 56? I searched for answers but I can not find a description of this strange error.
There are ways to supress them, need to search in the e46fanatics forum. That fault however is not responsible for your problem with the fuel adaptations.
