Hi all, recently picked up a 2011 335d non-sport, north America market car. It does have options such as I-drive If that matters.

Vehicle has driver and passenger heated seats. Memory seat only on driver.

Passenger heated seat doesn't work. Pushing the passenger seat heater button does nothing. Button doesn't light up. Button command is recognized using ProTools when button is pressed. All other seat functions work.

Moving under the seat, there's no +12 or ground at module (connector x013709 pins 7 and 8, respectively). Also no +12 wire populated in pin 4 from fuse f10.

At the main connector between the floor and seat harness (x279) at the seat side, pin 9 is the wire that needs +12 and pin 8 needs ground. Neither of these pins are populated on the vehicle side of x279. Also fuses 68 or 49 in the fuse box aren't wired into the box to even power this circuit (the diagrams are very contracting on which is a proper fuse for this circuit).

I tried moving the +12 from pin 4 to pin 9, and gnd from pin 13 to pin 8 to see if the seat heater worked but it didnt. Maybe I still need power to pin 4 of the module connector??

Also the seat is dated 2011 so I believe it's original.

I've been searching and this thread was the most helpful so far but the OP hasn't been back to update with more info.

So what I need to know is, if I buy terminals, populate the 2 powers and 1 ground, do you guys think that will work? Or do I have some bastard equipment mismatch that's going to involve software coding or something? At this point im pulling my hair out trying to figure out a solution but I'm at a crossroads and don't want to waste money travelling down a path that doesn't fix my issue.

Any insight would be greatly appreciated!

Thank you very much! Looks like I'll be buying the donor connectors on eBay so I can install the jumpers in a little more OEM fashion.
