A coding option for the IHKA (HVAC computer) known as “hot country” delivers more air to the center vents to maximize air conditioning cooling.

As far as I’m aware, the IHKA can manage the cooling output of the temperature control (Integriertes Heizung und Klima automatic).
Tech documents:
When “hot country” is selected, IHKA programming has been improved to generate greater cooling output. (Defrost and footwell vents are closed to let in more center vent air for the coldest air possible.)
Though it is unclear why there are different part numbers for the cooling fan parts (fan assembly, shroud,…), I do see them.
When a hot nation is selected, the IHKA programming has been improved to produce more cooling output. (Defrost and footwell vents are closed to let in more center vent air for the coldest air possible.)
The two blower motors in the E82 1 series purportedly have differing wattages (source). Additionally, in some older BMW models, the various climatic versions might have various oil coolers and mechanical/hardware variations.
I’m not sure where I was looking before, but I don’t see any different part numbers for the fan on the F8x.
To prevent condensation from freezing inside the hoses, I would anticipate “cold environment” hoses to be better insulated, but I don’t see any different part numbers for any of the hoses in the F8x.
Take the crankcase vent hose (number 7), for instance, where one may anticipate a difference if there is one:
Perhaps there is no change for the F8x, but I still worry if this will cause issues in extremely cold areas. I know nothing at all about the “cold” vs. “hot” climate.

I would anticipate that hoses used in cold climates would be better insulated to prevent condensation from freezing inside the hoses, but I don’t see any hoses in the F8x that have different part numbers.
Perhaps there is no change for the F8x, but I still worry if this will cause issues in extremely cold areas. I have never experienced a cold or hot climate before.
It seems strange to me as well. All 2018 M4 have been “Hot Climate Version,” especially now that I’ve been looking over the latest Canadian inventory. Even checking models from 2016 to 2017 yielded the same results for me. The majority of Canada experienced a harsh winter this year, so you’d think the vehicles would be prepared for the elements.
Version Z4 S823A for hot climates And what is that?
I live in Chicago and I’m looking at a 2007 Arizona car with the build sheet reading S823A Hot-climate version. Is there a version for chilly climates, or is this just a software setting for the heat, or what? Or am I allowed to leave it as it is?
After a quick check, it seems that all BMWs sold in the US are “hot-climate” models, while all vehicles sold in Canada are “cold-climate” models. There doesn’t seem to be anything involved besides the IHKA’s coding (ventilation). However, I should mention that my GT1/DIS diagnostic computer frequently queries me about a vehicle’s “auxiliary heating.” This option is unknown to me, and I assume it is only available in northern Europe (maybe Canada).
Yes, the fan setting is all that is changing, as the air conditioner runs at its maximum sooner.
For Chris: In Europe, you can purchase an aux heater for a BMW from the manufacturer or have one fitted at a dealership. Since they make use of the heater hoses, I have seen a few in E-46s and they are a HASSLE to bleed out.

A coding option for the IHKA (HVAC computer) known as “hot country” delivers more air to the center vents to maximize air conditioning cooling. Since “normal” is the coding option for hot nation, I would guess it’s a rather regular occurrence.
When the setting for IHKA is “hot country,” the programming has been improved to produce more cooling output. (Defrost and footwell vents are closed to let in more center vent air for the coldest air possible.)
