Hello,

I have a 2009 MB W212 E220 CDI with a defective ecu. The ecu has been changed once and reprogrammed with Xentry with "read and transfer data to new ecu"...

However, the error has somehow been transfered to the new ecu, and I cannot preprogram it with Xentry. That is why I now need to clean the ecu and make it virgin again so I can reprogram it again from scratch.

Can anyone please advise me to a good way to erease and/ or restore this ecu? I have at the moment the following tools: Xentry 1/2013 with developer mode, Galetto 2, BDM, Galetto 3/4. Avdi Commander.....

Here are a log from the car taken with AVDI:
