A lot of Fanatec wheel rim features such as Rev LEDs, and extra switches, knobs etc do not work on XBOX: Link
This has been the case for years unfortunately, and there doesn’t seem to be any light at the end of the tunnel.
Fanatec say it’s all to do with the extra inputs/outputs not being supported - apparently only standard controller inputs/outputs can be supported on XBOX peripherals, despite other wheel manufacturers being able to achieve this. Whether the issue is on the Fanatec or XBOX side, no one is really able to tell - both companies tend to point to one another.
Bottom line: DO NOT buy Fanatec gear if you plan to use it solely on XBOX. Similar issues do not exist on PC or PlayStation.
I know PC has no issues and as a ex-XBOX owner (for this very reason), I can personally confirm no issues on PlayStation with all the extra gizmos on my formula v2 wheel, unlike XBOX.
