Hi, I have dash from Superb II and after changing mileage it shows Error on display and in dtcs is checksum error. Can somebody help with this ?

And another question: Is it possible to read NEC for editing welcome logo and messages on maxidot display ?

Tried with carprog and avdi, nothing changes and can't read immo.

The data (eeprom) is corrupted. Immo was working good before changing mileage, it was showing immo active message but after changing mileage immo active message isn't showing and mileage is error now. In the dump where immo data probably could be stored they aren't there. I was looking in other dumps from 24c32 nec clusters and this area is not like my. My is full of FF FF FF FF FF..... Is repair possible ? Mileage was changed in carprog (Shitprog clone) from 244610km to 0. They tried to read it again with carprog and it shows 655xxxkm.
