Hi

I have a problem with an EIS from a W215, 2155450008 Q3. I wanted to create a new key because the last key was lost. Reading about IR with CGDI did not work. So I have desoldered CPU 1 (1D69J). I read it with ETL, but something went wrong. The dump is broken.
So I have desoldered CPU 2, reading is ok.
Can someone help me with the repair of the data?

ecu 1 is a backup of cpu 1, should still work if you have a woking key then auto repair cpu1

do you have a working key or you need key file to write to key?

what type of key you have?

I have successfully read the key data from dump

Sorry for the late answer
That is not completly correct. The data of the two CPUs are not 100% identical. Auto repair with a working key did not work either.
I was able to fix the data with the help of CPU2.
Problem solved.

But many Thanks for your help.
