I bouth 535d 2014 with comfort seats and have same problem. Check to see if the seat is getting power. If it does, your seat module is most likely the problem. If it doesn't have power then it's either a fuse or a damaged wire somewhere between the fuse box and seat. The heated seats are controlled by the bus system so there’s no wires from the switch to the seats. The switches go to a module that activates the seat heater. The body control module operates the heated seats windows etc. it could be a bad module, short somewhere, or it could be a programming issue.

I bought a Corbin seat and wired with the BMW plugs and it doesn't work either, so something with the bike and not the seats seems to be the direction things are pointing. I checked the voltage in the plug for the front and it shows 8.3 volts with the heat turned off in the menu and 10.3 volts with the heat turned on, regardless of setting.

When I press the seat heater button on the center console, the green light comes one for about a second and then turns off again. The passenger seat heater is fine. I have just bought a set of black leather E92 seats. They are full electric, with memory, heating, and air bags. Do you know where I can get a wiring diagram for them?
