I did a complete injector rebuild on my 2007 W204 with OM646.811 engine. After I did everything correctly, the car runs much better. However, the injector count values remain the same when I check the actual values via the Xentry engine smoothness monitor.

I tried to perform a Quick Teach-In for the zero quantity calibration values at the 230.00 bar and 600.00 bar calibration points. I have tried this many times in different conditions, but the result is always the same. All conditions (temperature, quantity, etc.) required to perform this procedure are met, but when starting, a yellow screen appears and after 1 second an error is displayed (images attached).

Any help would be greatly appreciated!

Self-calibration while driving (engine warmed up, coasting without load). This parameter does not affect the smoothness of the engine operation. It is necessary to determine the injector reaction time from the moment the command is given to the result of its execution. Fine tuning in addition to injector calibration codes.
