VW Golf 4 1.6 Simos 3.3 Immo Off Please

[szwajcarek]

Hi
I have a problem with Golf 4 and immo off. I red 93c76 as 16bit with Wellon programmer. I have programmed immo off dump made with ecuvonix but car did not start and no communication with ECU. After writing ORI file still no start and no communication. Is it possible that wrong EEPROM content has corrupted flash ? Could you please take a look at my dumps and make immo off ? Thanks in advance.

Hi
I have tested at least 15 solutions, and they are quite similar so I think they are all working. Car does not start, no communication with ecu and Tacho, even with ORI File. ECU was blocking transmission becuase after disconnecting W-wire from Tacho plug - I can communicate with tacho. I decided to desolder Flash 29F400BB and red it. 29F400 content is corrupted and it looks like that it happend after programming 93c76 with immo off (ECUVONIX). I guess that ECUVONIX solution did not cuased the problem but ECU itself.
My question is if someone is having backup files - EEPROM+FLASH (at least Flash) from this ECU ?

Hi
Problem solved! The Flash was not corrupted, the ECU was dead! Do not ask me why. Both solution worked fine. Thanks
