Seat massager fault code 8029B7

Hey everyone,

I drive a 2013 F10 535ix, my drivers side seat massager shuts itself off after 30 seconds or so of struggling to do anything. I took it into my local independent shop and they pulled the following fault code: 8029B7, Active seat: Cam motor or cam switch, short-circuit or open circuit. I'm struggling to find anything called a cam motor or cam switch on OEM parts sites, or a good description of how this system operates.

Can anyone help me narrow this down? Hopefully to the point where I can replace a part myself. Thanks!

I went to the TIS website...generically selected for an f10 535i then typed "ACTIVE SEAT" in the search box. This brought up multiple results...one of them being the wiring diagram for the active seat...then looked for the driver's side active seat module. It eventuallly lead me to the link below...if you click on it and read through the material...it discusses the "cam" used to actuate the active (massaging) cushions...as well as having an illustration of the cushion and the location of the cam:
