It looks like the second interface is from a 2007 Q7 and has a different software version than the one on A4 8K. Does anyone know if I can install the same A4 software version on the q7 module? I assume copying eeprom 1:1 could solve it? I tried to update the firmware via CD but it does not change the Q7 software.
I already tried resoldering the eeprom but due to the different software version, the new module went into CP.
