If this is still the old unit with broken PMU and replaced based on the logs Vi and Vo the input and output from the PMU is fine. But I don't know if the hash number you talking about is needed to be replaced with the same PMU with the same hashes or hash number.
I heard that you can program them to make sure the PMU will work but it should be compatible with the current MM version.
I think the only man who can help you with this is to contact
HagssFIN he is the one who has lots of experience with Avalon units.
