BMW X3 E83 MS45.0 Checksum error

[elecautocr]

Hello members:

I have a BMW X3 E83 2.5L gasoline with Siemens MS45.0, car does not start DTC 2830 (dme-self test checksum failure) is present. I fixed the checksum in Eprom file using Winols but the problem persist.
Maybe the problem is in eeprom or mcu files.

ECU is Siemens MS45.0 5WK93032 7561380 software 7561505

Can any of you fix the checksum in eeprom and/or mcu ? or Do you have good files (eprom,eeprom,mcu) for this car ?

Thanks very much

In fact of ews ... you need your original eeprom!
