A brake pad wear sensor kit for the Bmw M140i does one critical thing that a pad change alone cannot: it ensures the brake warning light on your M140i dashboard accurately reflects the condition of the next set of brake pads. Without a new sensor on the Bmw M140i, 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 M140i. On Bmw M140i vehicles where a previous service skipped the sensor, the brake warning light may also remain on permanently after new pads are installed on the M140i.
The kit for your Bmw M140i includes the brake pad wear sensor probe unit manufactured to OEM contact resistance and threshold depth for the M140i monitoring circuit, the wiring connector mating with the Bmw M140i brake monitoring harness where required, the retaining clip or mounting bracket securing the sensor to the M140i brake pad or caliper correctly, and in pad-inclusive kits, the brake pads for the Bmw M140i with sensor pre-assembled at factory-correct position on the M140i pad.
A brake pad wear sensor on the Bmw M140i is a calibrated component manufactured to trigger the M140i brake warning circuit at a specific remaining pad thickness. Too long and it triggers early on your Bmw M140i, sending drivers for an unnecessary brake service with significant M140i pad life remaining. Too short and it triggers late or not at all on the M140i, leaving the driver with no advance warning as the Bmw M140i pads approach the metal backing plate.
Wear sensor compatibility for the Bmw M140i is more exacting than most brake components. Probe length, contact resistance specification, and connector pinout must all match the M140i brake monitoring circuit exactly. A wrong-spec sensor on your Bmw M140i either triggers warnings at the wrong pad thickness or fails to connect to the existing M140i harness. Every kit in the GeoBrakes catalogue is sourced to OEM specification for the Bmw M140i exact year and model, with front and rear positions listed separately.
How do I know if my Bmw M140i has electronic brake pad wear sensors?
Check your Bmw M140i owner's manual for a brake pad warning light in the instrument cluster section. Use the GeoBrakes vehicle selector to confirm whether your Bmw M140i application requires an electronic sensor kit.
Can I buy the wear sensor separately from the brake pads for my Bmw M140i?
Yes. GeoBrakes carries sensors as standalone components and as part of sensor kits for the Bmw M140i. If replacing M140i 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 M140i.
Will the brake warning light turn off automatically after installing a new sensor on my Bmw M140i?
On most Bmw M140i vehicles, the brake pad warning light turns off once the new sensor is correctly installed and the ignition is cycled. On some Bmw M140i European platforms, a diagnostic scan tool reset may be required. Check your M140i service documentation if the light does not clear after installation.
