Remove phisicaly the eeprom of ecu and read with upa or X_prog if I rmember bad is 95160 spi read and post. Is only one way to replace the ecu. Post the result in ths thread and I decode :) ,,,, OK?

Hello. Have the same problem. Maybe someone can post file for flashing using VAS?

Thanks a lot in advance.

How to check is pcr2.1 ecu locked or not with VCDS:
Engine-Advanced measure blocks- tick( X_ECU_TYPE_LVSWMD_ISSAMPLEMODE) _if PRODUCTION ecu is locked, if SAMPLE ecu is unlocked.
Hope this will help.
