Hi all, this ecu came to me for dpf delete, when I received the ECU , it was clear that it had been opened already, I didn't even have to add heat, the lid just peeled off by hand, I've done a couple of these ECU's in the past with no issues, so I connected kess on the bench and hit I.D, it ID'd no problem and it showed LOCKED, so I went ahead with unlock procedure using ktag, everything seemed to go fine, but when I try to connect kess again I have no communication, I tried pcm clone and still no communication, so drove down to the guy and put it back in the car and still no communication, nightmare, do i need to get him another ECU or is there any way to get this one working again ? I have the original backup eeprom from the ktag unlock saved, any help is appreciated guys, cheers.
