ZVW  Siemens PCR2.1 faulty by unlocking
Hi!

I have a problem with PCR2.1 (Golf 6 1.6TDI). I wanted to unlock it directly in eeprom, but reading by programmerwas messed up. I thought it was ok, VIN and immo data were good so i have unlocked it and write. Car is starting but i get eeprom eeprom (ecu internal failure, is no coding and no injector codes). Flash reading by obd is not possible too. So i have downloaded eeprom from antoher car and make "hybrid", one eeprom from two (i put immo data from old to new). Now everyting is ok, car starts i can read flash by obd. Problem is I can't write modified flash - ecu is rejecting (original writes ok). I have tried to unlock it, no success. I make second unlock, without success. Next i have changed bits for unlocking from messed up reading, no success. Now I don't know what to do. Can you help me?


P.s. eep6g is messed up reading, g6final is eeprom which is nowe used.

RE: Siemens PCR2.1 faulty by unlocking
Problem is not with unlocking, problem is with messed up eeprom reading, where unlocking bits are messed up
