    Default A6 C5 dash swap?

    I need to swap dash on a6 c5 2.5tdi . For easy replacement with no coding can I just swap over MCU and eeprom ? Could I rewrite the mcu s using UPA-USB or something like that? I have attached dumps too since I can not read out the pin codes myself from the cluster, since the 93c86 appears to be encrypted.

    do not play with eeprom swap, it can be different crypto versions,post here dumps maybe someone write you pin codes and you can easy swap dash with vcds

    If for some reason swapping the new dash does not work with vcds, the old dash should still work?

    tried it again, the pin codes are correct, but VCDS says that System not ok and adaption does not work. Tried to swap with FVDI too, still nothing. Only eeprom swap does not work on this cluster. But since the dash blinkers are not working the MCU could be faulty. FVDI has Flash read tool on it, but can it write it ok too?


    The original cluster has VDO crypto version D15 and replacement has crypto version D17, maybe those different versions dont play out well? I tried to swap eeprom data, that did not work. I will add the decrypted dumps in the evening, maybe somebody knows how to manually transfer immobilizer etc info to make it work.
