2004 BMW 745Li Coolant Temp
I get that this thread is ancient but this could be helpful.

I recently setup ELM327 WiFi with Galaxy S5 Android spare phone
with TorquePro 2 ($4.99).
Besides being awesome, it is showing the following during
normal operation and cycles between the following temps:

Low Temp = 221.0 F (105.0 C)

High Temp = 226.4 F (108.0 C)

Occasional Temp Super High = 231.8 F (111.0 C)

(Appears that the ODB is delivering C and Torque Pro 2 is converting to F.)

So the super high temp, while concerning, gives convidence
that the ODBii reading is not pegging at 226.4 F

So my issue is that I have a problem with my AC.
It usually works fine but over 85 degrees road temp
the cooling just stop for 10-20 minutes, then comes back
strong. (I just paid money at a reputable shop to tune up the
134a refridgerant, so this should not be the problem.)

This is also a problem when road temp is 102 F or higher but occurs as low as 82 F.
So far, I am unable to confidently say that it is due to over-temp
of engine since it seems to be cycling in the good range and
everything I'm reading says that older M60 V8 runs at 195 F and
current M62 runs hotter at 226 F.

I got the spike at 231.8 yesterday, and I did have the AC
cut out for 10 minutes, but I'm not sure if they are related.

Can anyone advise if the brain is shutting off the AC compressor on overtemp of coolant; presumably to unload the engine of this task?

More on ELM WiFi: Since it is WiFi (and BlueTooth not available for iPhone)
I am unable to be connected to the internet AND the ELM327 WiFi hotspot simultaneously; which is a pain, since I have to run 2 phones since my iPhone apps won't allow me to specify LTE and they revert to ELM327 WiFi hot spot even if no internet available.
(Same problem when flying my drone?)
