I imagine then the extra display portion on the high cluster reads info from the can bus?

I'm pretty sure that the display section on the high cluster is as you suggest,
80stech. Data is sent to this display by various modules via the I-Bus (not CANbus), just like the MID display.
Given that the high temp warning originates in the LCM module, it's possible that this I-Bus telegram is still interpreted by the low cluster and turns on the red over-temp lamp (LED?). If so, then the re-code is possibly the same for high or low cluster, esp. given that it's a re-code in the LCM.
Worth a crack...
BTW, is there an audible alert to go with the red lamp on the low cluster, as there would be with the CC message on the high cluster? If so, this would be further support for the theory that both cluster types receive the same telegram from the LCM but just display it differently.
