Did you turn them on?-lol! Hot here in GA too and there is no comparison in my M and P car seats.

I found this on another forum. I'm between cars right now, so I can't test. Credit to user JEG23 at bimmerfest:

Front active seat ventilation

The seat cushion and backrest surfaces are cooled by means of integrated fans.

To switching on press the button shown below once for each ventilation level. The highest level (coolest) is active when three LEDs are lit.

366730

The default temperatures are:

Seat cooler position 1 cushion Werte=23 (35° C)
Seat cooler position 2 cushion Werte=21 (33° C)
Seat cooler position 3 cushion Werte=1E (30° C)
Seat cooler position 1 back Werte=23 (35° C)
Seat cooler position 2 back Werte=21 (33° C)
Seat cooler position 3 back Werte=1E (30° C)

The settings can be adjusted by changing the werte values in the following codes. Remember the werte values are in hexadecimal.

Front driver seat cushions:

SM [6d]->3008 SITZKLIMA, 13->SKL_TEMP_SOLL_ST1_KI
SM [6d]->3008 SITZKLIMA, 13->SKL_TEMP_SOLL_ST2_KI
SM [6d]->3008 SITZKLIMA, 13->SKL_TEMP_SOLL_ST3_KI

Front driver seat back:

SM [6d]->3008 SITZKLIMA, 13->SKL_TEMP_SOLL_ST1_LE
SM [6d]->3008 SITZKLIMA, 13->SKL_TEMP_SOLL_ST2_LE
SM [6d]->3008 SITZKLIMA, 13->SKL_TEMP_SOLL_ST3_LE

Corresponding values can be found for the front passenger seat in the SM [6e] ECU

A little off topic, but has anyone tried changing the values for the following:

SM [6d]->3000 SM_GLOBAL, SA_MEMORY_ZEIT

Looks like option 3 will retain the last seat settings permanently (heating, ventilation, massage). Wish I had seen this earlier.
