w203 4j74y EZS Repair

[casiopaya]

Hi folks,
i have w203 a2035450108 EIS / EZS which is faulty.

It doesn't recordnize the Keys
Can't open the doors via RF Keys
Diagnosis connection OK!

I read out one of the mcus (4j74y)

Is the dump ok ?Or is it invaild?

What should i do if the data is invaild?
What is the easierst way to fix that??

I can read/write/ reset ESl ( ESL Programmer)
I can Write Nec-KEY ( Nec Programmer)
I can read/write ECU ( ordinary Programmer)
I can read/write HC908 (ETL Programmer)

when i load the eis file from vanos ,
the programm doesn't show me the ssid.

Do i really need to takeout both mcus?

Are the generated keydumps for Old keys or for new small keys?
