HI,to all members
I have a problem with MB sprider ECU A646 150 63 72 that diagnostic can not indedify and engine not start at all. What I did??
1. I read ori file with clone KESS to and accidendly write another file to the ECU. After that engine
did not start and KESS does not able to communicate with ECU because the ecu did not responce.
2. After this I cut the ECU shell and read all files using KTAG clone. Also I write the ori file back to
flash but the engine does not start and ECU no responce again.when read file again with Ktag I notice a different
between this and the file i wrote previously.
I think that the wrong (accidedly) file change the <<EPPROM>>.
As a result  I need a virgin file to repair this problem. Would you help me PLEASE???
Thank you all friends and I hope for any help from you.
