Understanding the Brake Pad Light
The brake pad light serves as an indicator that your brake pads have reached the end of their lifespan. It illuminates when the brake pad sensors detect a reduced thickness, usually when there is approximately 2-3mm of pad material remaining.
Safety Precautions
Before performing any brake work, ensure your vehicle is parked on a level surface and the parking brake is engaged. Wear appropriate safety gear, including gloves and safety glasses.
Materials Required
- BMW diagnostic tool (e.g., Carly adapter, BimmerLink)
- Bluetooth-enabled device (e.g., smartphone, tablet)
Step-by-Step Instructions
Using a BMW Diagnostic Tool
1. Connect the diagnostic tool to your BMW’s OBD-II port.
2. Launch the diagnostic app on your Bluetooth-enabled device.
3. Navigate to the “Brake System” or “Service” menu.
4. Select the option to “Reset Brake Pad Wear Indicator.”
5. Confirm the reset by following the on-screen prompts.
