Skoda Superb Airbag Sensor - Scrap Needed

Hi, My airbag warning light has come on. I took it to the garage and a mouse had chewed through a wire to the sensor. I'm told the bit I need is a G265 sensor, a driver side rear airbag sensor. On googling I'm presented with speed shaft sensors but not airbag sensors. Does anyone know what part this (pic attached) is and where you can get them from. I've been told if I can get one from a scarp yard with 5 inches of wire on it could be used.
