Hi,I have one broken Jaeger dash from Audi A4 2000year and then I got one working from scrap yard, numbers are the same but on the software on MCu is diferent, old one is 908 with 7.91 and new one is 908 with 7.82.Question is if I swap MCU 912dg ( there is km and immo ) from old to new will this work? Thanks

You can not do that .
Read both original and new hc12 and post here.

Read Eeprom of both clusters and put back original MCU in new cluster.

Yeah just cop your eerpom to new cluster and it will work. It can be done via OBD if you have the proper tools

This is Immo 2 , very easy to do it.
Write original eeprom back to New cluster .

After that just adopt key with VCDS to new cluster and you will be good to go.
