So I called the dealer to get an understanding of this and basically it seems like the 458 brake pad sensors cannot be purchased separately and are only a part of the full OEM pads package. For those who want to run any aftermarket/more aggressive pads for 458, it seems like the "Brake Pads worn" warning will have to stay on. Has anyone else had any experience about this? Can the light be reset only by dealer? My friend's car's light stayed on even after he erased all codes using OBDII scanner.
