Title: RS4 Cluster for S4, copy of Immo
Post by: OberlandRacing on February 20, 2026, 04:15:13 PM
Hello Guys,
I have an S4 & RS4 Cluster on the Bench. I need to copy all Immo informations from the S4 to the RS4 Cluster. I dont have the Car or ECU here.
I never done it, and would like to ask if someone can check what i´ve done.

I did copy from the S4 file to the RS4 Cluster file:
-ViN
-SKC/Login (was "tricky" because of swap byte)
-Immo Key (handshake between ECU/Cluster)

is there any Checksum that i need to correct? any tool for that? 
Checked my changes with VAG EEPROM Programmer seems good so far, did i overlooked something?

Thanks!
