Audi A6 2018 DEF error

[bob191919]

I changed mileage in cluster with DP4(elprosys).
Had to read key file by OBD, then change eeprom in cluster.
After edit cluster mileage is OK but DEF showing in display.

Can somebody correct checksum in eeprom file so DEF is not showing anymore?

file with needed mileage: OBDII_C12_0319_20240518135419_238619KM

Or do I need to reflash cluster?

Cluster: 4G8920935A
Bosch RB 8 cluster


NB. when I restore original file still DEF error.
tried to repair DEF with DP4(elpro), digiprog4(tacho.de) and AVDI Abrites. All failed

What does the support say?

No support for this.
Anyway update for DEF problem. Client decided to go to competition and solved problem there with ODIS and checksum correction. I just received my VNCI 6154A and have installed ODIS-S and ODIS-E.
They could not wait for me to try.
If somebody knows how to do it in ODIS, let me know

Thanks all, and specially @wanaruss he could also solved problem with ODIS.
