Hi, andys1977.
To make cluster working, you must write back encrypted file if jou have it!
if not, try write decrypted file and after set cluster back to adapted mode 6,
in new mode cluster not communicate with engine ECU.

@armi , thank you for your reply
first time read , i set cluster to new mode and then read decrypted file
and make backup.
then write back decrypted file , after that cluster went dead , speedometer went halfway and stopped.

then i write back as encrypted way and cluster comes on but with errors

Audi crypted clusters RB4 are very complicate but vag eeprom 1.19 is good program for those clusters. Backup you must always make as encrypted (read encrypted), before setting to new mode. Writing back this backup file make cluster working 100%, even after ERROR , SAFE or completely dead. If i understand right, you have only decrypted file , this file has not cryptomask for this cluster, i need more time to help you to search similar bin in my audi clusters file collection.
