A8 D2 Immo Code Reading

[WeltraumMexikan]

Hi,

i'm searching for a way to read my Immo Code from my A8 D2 (MJ 2000) with Crypto.
I need the Login Code 'cause i want to replace the old Cluster. It malfunctions not directly but the Screen in the middle ist blurry and slowly dying..

A 'new' Cluster is already there but i have absolutly no experience at this sadly.

I tried to get a dumpo from the Cluster but HxD only reads two lines, all other lines are just 55 (FF in hex).
The New Cluster has a 24C17 Chip, i guess the original Cluster too.

Also tired DigiProg 3 to read EEPROM, that didnt work aswell...

even tried to read the EEPROM from the new Cluster with a Programmeer directly of the Chip... didnt work..

Could somebody introduce me how to get a correct Dump and how i can get the Login of the Originial Cluster and of the Replacement aswell?

If all of it didnt work is there any way to do a Factory Reset to a used Cluster?
In that Case i could take it and get it done by the local Audi Dealer i think, but they need a "unused" Cluster (or factory reset)

Greetings from Germany, hopefully sombody can finally help me...

Are there any recommendations for a better Reader?
Precxedure is the same i guess?
So clip it on the EEPROM or is there a Reader to do it via OBDII?
Also tried tools like VAG Commander etc..
