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..
