Note:Here i you want to make the procedures simplify,you can choose ME9.7 ECU Renew Cable.No need to disassemble the ECU and soldering cable connectors.It can reduce operational risk of ECU damaged.



Open KTAG software.

Then I Choose “Mercedes” “S (W221)” and “S350 3500 V6…BOSCH ME9.7”.


Choose plug-in “P102”.


I clicked “Read” and wait for a while.

Then Save the bin file.

Finally, i successfully used K-TAG Auto ECU Programmer to read Mercedes W221 ME9.7 ECU !


Then write procedures is same as reading procedures.And before you write a new ECU data file back into ECU,you would better make a backup.
