Replace Engine and need adaptation

[user041982]

I’m having an issue with just one injector which from time to time gives an electrical error. It’s one from the piezo electric ones which MB has replaced to solenoid one. But after coding it with Xentry it looks like the error is gone.

After renovating the engine or replacing it with another one, you should delete all adaptations and delete all errors.
Start the engine and wait until it warms up at idle speed, observing all actual engine operating parameters.
Misfiring may be caused by even a minor fault such as - too small a gap in the spark plug.

Personally I would send it to the dealer and let them diagnose it then once they give you the read out weigh the option of paying the dealer to do it correctly or paying the mechanic to TRY to fix it. A misfire does not mean a bad engine. 2hrs with the dealer diagnosing could save from another engine swap and thousands.
