Bank 1 is same side as cylinder 1. In turn cylinder 1, 2 and 3 are on offside. So....bank 1 is right hand or offside. I believe this would make your fault code reporting correct.
Confirmation from US website: Front driver side bank 2 sensor 1, rear driver side sensor 2, pass side is bank 1.
Glad you got a result albeit a frustrating one
. Take it there were no signs of cable/loom faults.
