hi guys, I am trying to do the correction km for a-class w169. I tried with digiprog 3 but that does not go with the adapter behind the picture with the caliper on the eeprom. I then read and edited the eeprom with carprog, revised and rewritten, everything is ok, the miles are up but as soon as I put in motion back the miles that were there before, what is wrong?
