Sensor doesn’t work
The fit was fine but it caused an error in the computer where both sensors won't read now. Error says "brake service needed". So now have to buy one from dealer and hopefully that fixes it.

The fit is not as good as OEM on the pads I have and I still don't get a measurement from it
