Swap eeproms. Or do it with eeprom programmer. So just clone flash with ktag. Clone ktag have this issue with that ecu. Ori works perfectly.

RE: Help,Mercedes ME2.8 Ktag clone error writing eeprom
After cloning was complete I examined files before and after clone with HxD editor and mpc file was identical also was maps,then examined eeprom file and vin was written in almost the complete file was
the same except for a few scattered digits maybe 10 or so in the whole file,so wondering if this is just a
false error,haven't been able to try ecu in car yet after clone,will report how car reacts to clone ecu....

Did you desolder eeprom and read/write off the board?

No I was trying to avoid that if I could ..I did read/write via boot mode according to pinout and ktag
instructions..

RE: Help,Mercedes ME2.8 Ktag clone error writing eeprom
Ktag 6.070 under Trasdata working like a charm on this ECU. R/W e2p/mpc/ext with no problems.

6.070, 7.020 under Ksuite never work.

Kess 5.017 under Ksuite 2.23 and 2.47 write good.

Car was w203 C32 AMG.

RE: Help,Mercedes ME2.8 Ktag clone error writing eeprom
Yes it was w203,but I have some good news,installed ecu last evening and car starts fine so this must be a false error..As I wrote in my 4th post after looking at the eeprom files all blocks that contain vin#
and immo data was written only a few hex digits at end of file were different and after more research I think those are dates and other non important information from factory writing..I'm using K-tag 2.25 7.020 version..
