Hi,

I have a problem with a BMW X3 E83. 

The DDE is broken and showing temp on max and car doesn't start.

Somebody tried to send the DDE in, but they couldn't repair it.

I tried cloning the DDE to a used one, but the error stayed and it showed EWS manipulation, and the error with temp on max is still there.
Even just cloning Eeprom didn't work. 
With the original file of the used DDE the temp on max is gone, but EWS is still present.

EWS DDE alignment didn't work. It showed no free space. 

I have the backup file from the original and the used one. Is it possible to turn the IMMO off or fix the data to get the used working in that car?

I will attach the files read with kess.

ori is the original ECU
ori_ersatz is the file of the used ECU

what do you mean with this checksum, it's good in eeprom, I don't understand, are you bragging or complaining?
