Ventilated seats
Picked up my 2020 840 yesterday and am puzzled by the ventilated seats. I barely noticed anything even when turned up to ‘full’ other than possibly a small bit of movement at the small of my back and a lot of additional noise from the ventilation system.
Am I expecting too much or are they generally pretty useless? |

Hi got my new 840i gc with ventilated seats September 21. Have to say I love them, yes they do increase the noise in the cabin however they do give a very pleasant stream of cool air to your back and a@@e even on the lowest setting. My old 640 gc didn't have them. For me a great addition.

Isn't there a way to code these so they are cooler? I am pretty sure you code the heated ones.

I think its the routing of the actual vents and fans, they don't connect to the air ducts.

Exactly this. The seat ducts take cabin air, not HVAC air. So, if your cabin is warm, the air blowing through the seat vents will also be warm.

mpop's Escalade and most other American cars blow cold air from the seat to the driver or passenger. Think of the air flow as flowing up from under the seat. In most European cars, ventilated seats suck moist air from the driver or passenger thru the seat. Think of the air flow as flowing down from the top of the seat. And since cold air is not being blown, there's no cooler temperature to code. Think of it this way - BMW offers heated and ventilated seats. Not heated and cooled seats.

My old 2013 infiniti M37 had air conditioned cooled vented seats. now those were instant relief from burning leather on hot summer days.
now these bmws on the other hand seem to blow hot air all over your backside on hot days, making your discomfort even worse. the car's cabin has to be completely cooled down to appreciate the vented seats unortunately. |

Bmw cooled seats are really subtle and a little underwhelming. Have been in every car ive had them in too. Oddly in my Ram it feels like im sitting on an air hockey table.

Yep as same for me with the wife's 2017 X5 vs my 2020 M850i coupe. It's likely not the performance of the seat blowers drastically improving but rather the cabin size differential.

According to this BMW blog post you get heated seats with the M Carbon buckets but for cooling it is completely passive, i.e., no fans to help move the air. |
