Siemens PCR2.1 faulty by unlocking - arti123 - 30-11-2017

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.

Problem is not with unlocking, problem is with messed up eeprom reading, where unlocking bits are messed up

I can restore your dump BUT need serial MCU TC1796.
PCMFlash can read or ECUFlasher, Smok, MPPS.
