Hi guys I have a bmw e60 525d with a programed ecu(dpf, egr, chiptuning) and as I found out the flash file is somehow corrupted and the ecu doesnt want to communicate sometimes, though i replace ecu and clone eeprom and flash but after cloning flash file its the same, sometimes it doesnt communicate or start the engine. So I only cloned the eeprom but now i get faut codes 46d1 internal 4 and 4a63 ews tampering. After doing some research I think i need to change ISN on the eeprom, but couldnt find how. Could someone help me?

Ecu part numbers are the same original and donor.
