FAQs
How does a brake pad wear indicator sensor work?
The sensor contains a small metal contact. When the brake pad wears down to a specific thickness, this contact touches the brake rotor, completing an electrical circuit that triggers a warning light on your dashboard.
What is the OEM reference number for this Bosch sensor?
This Bosch Brake Pad Wear Sensor is compatible with OEM reference 991 609 165 00.
Is this sensor compatible with all Porsche models?
No, this sensor is specifically designed for the front axle of compatible Porsche vehicles. Always verify fitment for your exact vehicle model and year.
Do I need to replace the sensor every time I replace brake pads?
It is generally recommended to replace the wear sensor whenever the brake pads are replaced, especially if the sensor has already triggered the warning light or shows signs of damage, to ensure continued safety functionality.
What is the length of this brake pad wear sensor?
The length of this sensor is 300mm.
Can I install this sensor myself?
Installation typically requires accessing the brake caliper and connecting electrical components. While possible for those with mechanical experience, professional installation by a qualified mechanic is recommended for accuracy and safety.
What happens if I ignore the brake wear warning light?
Ignoring the warning light can lead to severely worn brake pads, reduced braking effectiveness, potential damage to brake rotors, and increased risk of accidents due to compromised stopping power.
Troubleshooting
Warning light stays on after replacing pads and sensor
Ensure the new sensor is correctly seated and fully connected. Check the wiring harness for any damage. Reset the brake warning light system according to vehicle manufacturer procedures.
Sensor warning light does not illuminate when pads are worn
Verify the sensor is correctly installed and the wiring is intact. Check for continuity in the sensor circuit and the dashboard warning light system. The issue may lie with the dashboard indicator itself.
Incorrect fitment
Double-check the vehicle's make, model, year, and specific brake system against the sensor's compatibility list and OEM cross-reference number. Ensure measurements, like the 300mm length, match requirements.

Setup, Compatibility & Care
Setup: This sensor is designed to integrate directly into the existing brake system wiring for compatible Porsche vehicles. Installation typically involves locating the sensor on the front brake caliper, disconnecting the old sensor, and connecting the new Bosch sensor.

Compatibility: Before purchasing, it is crucial to verify that this specific Bosch Brake Pad Wear Indicator Sensor (MPN: 1987473605) is compatible with your Porsche's make, model, year, and specific brake system.
