You can test this file. Normally I would believe, that dashboard has hardware damage as you descripe. But I took now a dump same partnumber/version (here from DK) and transfered crypted km-value, all 3 crypted immo-blocks and vin from your dump. You have nothing to loose. :-)

Post result please.

Good luck

You can try this file. Maybe you can write it now with OBD? What tools you have?

I have problem with FVDI when I change a milleage in RB8.
FVDI change milleage perfectly but FVDI change few bites in immo data.
I read eeprom by clips and change milleage by FVDI. After that I read eeprom by clips and I made one file from two :P

I think FVDI makes some backup automatically , look for it in folders - if not there is an option repair RB8 DEF in FVDI
