Instrument Cluster issues after replacing CAN gateway

[neeldub]

Hey i have recently replaced my CAN Gateway controller (Original p/n: 4L0907468B) with 4L0907468C. Reason for this is because I am retrofitting Side assist. After I fitted it, component protection kicked in which disabled the sound system, it was only playing on the left side door speakers.
But now i'm havings issues with the instrument cluster and steering wheel roller and MODE buttons. The DIS isn't displaying the current radio station or track playing at the top and i can't access the listing or telephone options when pressing the mode buttons.

I had component protection removed by the Audi VW specialists in Harrow, which sorted the sound issue but not the instrument cluster.. they can't find any active component protection in other modules. As far as I know, I have coded the CAN gateway correctly as there is now no error codes from it. Nor did any of the coding changed for the other modules..

I did run a measuring value test on the steering wheel system and the buttons are working as they should.

any advise?
