Hi! I just bought a 2010 jaguar xf 3.0 td, and are having some troubles with code B0091-1C. Left side restraints sensor 1. I have checked in the door, and the b-pillar but cannot find the sensor.

I have checked the drawings of where it is supposed to be, but I cannot find it in the door. Does anyone have any ideas as to where it might be, or if there is another way to fix this?
