mb w210 ezs hash error

[exxl]

today have got one w210 in workshop with all key stopped working, have readed the upper motorola for try to calculate keys with skc but all key tracks have hash errors,

for the expert here one question can you repair only hash error in upper motorola so i can use skc to calculate keys or you need both motorolas readed

i will upload now the upper cpu bin file if needed i can read the other cpu too...

and also with repair hash error dump and generating keys with skc do i must make esl and ecu virign also or the key will start right away?

thanks for your help
