    Hi,
    I don't know exact answer to your question, but from what i have read the code in EEPROMs (chips) 101.03 and 101.04 is almost the same and in my opinion will be strange to not be like this. The ECUs have to be the same in practice although numbers on them will be different and I don't think that will be a issue or will have some noticeable difference between them, but haven't read about such change.
