No fog lights working

[cwoods1@live.ie]

Does anyone have any wiring diagrams for the front and rear fog lights on a 2011 b7. Car has fogs as standard. Front fogs are working on the cornering function, but not on the switch, although the light illuminates on the switch. Rear is not illuminating on the switch, no signal to the led. Working when back pinned so led is known ok. Any information greatly appreciated. I suspect a bad bcm, although when dismantled is spotless.
