Hi all I have just got kess v2 to read and write to my ecu on peugeot Bipper 1.3 hdi 2013 however everytime i try to read the ecu it gets to the end where it says [save to] and when i try to save the file it comes up with checksum error and shuts the kess program down .i am trying to delete permanent dtc p1564 and also delete dpf, Does anyone have a ecu file for this marelli mj8f3hw10p please so i i can download onto my ecu to clear this problem Hopefully or anyone got a cure to the checksum error ??
