So with mine I have the airbag fault in the dash. The heated seat flashes a couple times before going off. And if I try to use the directional pad to adjust the seat it pops the fuse. So appears to be a fault in the back rest portion. I swapped the driver and passenger modules and that did nothing to help. Passenger side all works fine. Super annoying not having the heated seat function as the driver and even my rear passengers have it. Even more annoying is that airbag fault I have to stare at in the dash and Nav. I was going to next inspect the controls on the side like the directional pad to see if anything looked unusual. I think looking at the diagram there are like three units related to the backrest that it could be.
