Mercedes Viano ecu bricked

[OHANAJAN]

Hi,
I have a Bosch EDC16CP31 ecu that had the wrong file written back into the ecu.
The ecu was done via bench mode and the file received was an OBD file, so after
writing the file into the ecu the vehicle didn't want to start. Also there is no
communication with the diagnostic tool.


I have done a boot recovery on the ecu and the file was written 100% to the ecu
but still the vehicle don't start and I cannot get the diagnostic tool to connect.


Is there a way to fix this ecu?


If I have to get another ecu which ecu's can I use?
This one's part number is 0 281 015 927 with HW: 25.08

Hey,

You could attach your readings to check, but sometimes these ecus doesnt survive opening to reach boot... I attach pic, where You can see which ecus you can use (Bosch part numbers).

Hi Milicija,

Attach is the original read file that was tuned before, original file and the recovery file

Milicija, thank you for the list of ecu's, do they have to have the same hardware number as the original or doesn't that matter?
