I think I might have found the Data Identifiers for tire pressure and tire temperature as tested on my 4BW. I haven't a clue if the same data is available for non-Blackwings.

I didn't like the coarse granularity for the tire temperature of just Cold, Cool, Normal and was curious if the data for each tire was available via the BCM module and I think I might have found it. Via the Torque (Pro) app and the aa-torque plugin, one can display the temperature of each tire on the infotainment system in Android Auto.

I tested the temperature data by blasting a wheel with a space heater and it behaved as expected; though I've not yet gained enough data points to know if I've founding the right scaling values.

Attached is the CSV file that can be imported into the Torque Pro app for testing. If anyone is interested and tests it out, I'll be curious in your results
