A disc brake pad wear sensor on the Bmw 220i Gran Coupe is your vehicle's advance warning system for brake pad replacement. It eliminates the need to rely on audible squealing from your 220i Gran Coupe to know your pads are getting thin, instead triggering a dashboard warning light at a preset minimum thickness on the Bmw 220i Gran Coupe, giving you time to plan the replacement before the pads wear through to the metal backing plate. Replacing a triggered sensor with every 220i Gran Coupe pad change is the only way to keep that early-warning system working for the next service interval.
The wear sensor on the Bmw 220i Gran Coupe is a small probe embedded in or clipped to the brake pad. When the 220i Gran Coupe pad wears down to the replacement threshold, the probe contacts the rotor surface. This contact creates a circuit change that signals the Bmw 220i Gran Coupe ABS or brake control module, illuminating the brake warning light. Once the probe on the Bmw 220i Gran Coupe has contacted the rotor, it is destroyed and cannot be reused. It is a single-use component by design on the 220i Gran Coupe.
Installing fresh brake pads on the Bmw 220i Gran Coupe without fitting a new wear sensor defeats the entire purpose of having a brake monitoring system on your 220i Gran Coupe. A previously triggered sensor probe is worn through and has no remaining material to detect the next set of 220i Gran Coupe pads wearing down. From day one of the new Bmw 220i Gran Coupe brake pads, the warning system is non-functional without a new sensor.
Wear sensor compatibility for the Bmw 220i Gran Coupe is more exacting than most brake parts. The probe length, contact resistance specification, and connector design must all match the 220i Gran Coupe brake monitoring circuit precisely. A wrong sensor triggers Bmw 220i Gran Coupe warnings at the wrong pad thickness, or not at all. Every sensor in the GeoBrakes catalogue is sourced to original equipment probe and connector specifications for the Bmw 220i Gran Coupe, with front and rear positions listed separately.
Do I need to replace the brake pad wear sensor every time I change pads on my Bmw 220i Gran Coupe?
Yes, on Bmw 220i Gran Coupe vehicles equipped with electronic wear sensors. The sensor probe on your 220i Gran Coupe is a single-use component. Once it has contacted the rotor and triggered the 220i Gran Coupe warning light, the probe is consumed. Always replace the Bmw 220i Gran Coupe sensor during every pad change.
Does my Bmw 220i Gran Coupe have electronic brake pad wear sensors?
Many vehicles use a mechanical wear indicator instead of electronic sensors. Check your Bmw 220i Gran Coupe owner's manual or use the GeoBrakes vehicle selector to confirm whether your 220i Gran Coupe uses an electronic pad monitoring system.
Can a faulty wear sensor keep the brake warning light on my Bmw 220i Gran Coupe on after new pads are installed?
Yes. If the Bmw 220i Gran Coupe wear sensor from a previous brake service was not replaced, or if the probe has been damaged on your 220i Gran Coupe, the brake warning light will remain on even with new pads. Replacing the 220i Gran Coupe sensor will clear the fault and restore normal operation.
