The BMW's just have fans in the seats moving the air for the back and the seat, I'm assuming that's why the option is called vented seats, if it was thermoelectric like the Jag they would probably call them cooling seats or something is my take on it.
I use thermoelectric cooling on one of my CNC's, it does produce pretty cold air compared to ambient. It's completely different than just using a fan to push air.
