Of course it doesn't work because your pads don't have the wear sensor. On cars wich have this system, the front pad on left, has an sensor and a jack connected to the car. The car that doesn't have the wear sensor have normal pads, with no wiring or else. I bought DS Performance pads for my
Cupra and they have the wiring and jack, but the car doesn't have them so i had to cut it off and use the pads with no sensors.
