Bmw I3s Brake Pad Wear Sensor Kit in US

A brake pad wear sensor kit for the Bmw I3s does one critical thing that a pad change alone cannot: it ensures the brake warning light on your I3s dashboard accurately reflects the condition of the next set of brake pads. Without a new sensor on the Bmw I3s, the warning system is non-functional from day one of the new pads, there is no advance notice for the next replacement cycle on your I3s. On Bmw I3s vehicles where a previous service skipped the sensor, the brake warning light may also remain on permanently after new pads are installed on the I3s.

What Is Included in the Bmw I3s Brake Pad Wear Sensor Kit

The kit for your Bmw I3s includes the brake pad wear sensor probe unit manufactured to OEM contact resistance and threshold depth for the I3s monitoring circuit, the wiring connector mating with the Bmw I3s brake monitoring harness where required, the retaining clip or mounting bracket securing the sensor to the I3s brake pad or caliper correctly, and in pad-inclusive kits, the brake pads for the Bmw I3s with sensor pre-assembled at factory-correct position on the I3s pad.

Why the Sensor Probe Specification Matters on the Bmw I3s

A brake pad wear sensor on the Bmw I3s is a calibrated component manufactured to trigger the I3s brake warning circuit at a specific remaining pad thickness. Too long and it triggers early on your Bmw I3s, sending drivers for an unnecessary brake service with significant I3s pad life remaining. Too short and it triggers late or not at all on the I3s, leaving the driver with no advance warning as the Bmw I3s pads approach the metal backing plate.

Signs the Wear Sensor Kit on Your Bmw I3s Is Due

• Brake pad warning light illuminated on your Bmw I3s dashboard
• I3s warning light that stays on after a recent pad change, indicating sensor was not replaced on the Bmw I3s
• Brake pads on your Bmw I3s at or approaching minimum thickness on inspection
• Worn sensor probe visible on the I3s brake pad during a brake service inspection

Why GeoBrakes for the Bmw I3s Wear Sensor Kit

Wear sensor compatibility for the Bmw I3s is more exacting than most brake components. Probe length, contact resistance specification, and connector pinout must all match the I3s brake monitoring circuit exactly. A wrong-spec sensor on your Bmw I3s either triggers warnings at the wrong pad thickness or fails to connect to the existing I3s harness. Every kit in the GeoBrakes catalogue is sourced to OEM specification for the Bmw I3s exact year and model, with front and rear positions listed separately.

Frequently Asked Questions - Bmw I3s Brake Pad Wear Sensor Kits

How do I know if my Bmw I3s has electronic brake pad wear sensors?

Check your Bmw I3s owner's manual for a brake pad warning light in the instrument cluster section. Use the GeoBrakes vehicle selector to confirm whether your Bmw I3s application requires an electronic sensor kit.

Can I buy the wear sensor separately from the brake pads for my Bmw I3s?

Yes. GeoBrakes carries sensors as standalone components and as part of sensor kits for the Bmw I3s. If replacing I3s pads that did not include a sensor and the existing sensor has already triggered, a standalone sensor or sensor kit is the correct purchase for your Bmw I3s.

Will the brake warning light turn off automatically after installing a new sensor on my Bmw I3s?

On most Bmw I3s vehicles, the brake pad warning light turns off once the new sensor is correctly installed and the ignition is cycled. On some Bmw I3s European platforms, a diagnostic scan tool reset may be required. Check your I3s service documentation if the light does not clear after installation.
