Clio 2002 1.4, Airbag light?

Evening all,

I hope someone can help, the airbag light has appeared on my girlfriends clio, i have taken it to the local garage and they say the light will not reset and its coming up with a fault code B1036, passenger side airbag sensor short circuit.

The car has a passenger dashboard air bag and one in the side of the seat, would anyone know where the sensor is?

I think that the problem may have been caused by the leaking sunroof issue and that the sensor may have gotten wet, i have since fixed the leaky sunroof.

Please can someone help

Many thanks
