The persistent glow of your E36’s brake pad warning light can be a nuisance, but it’s a vital safety signal you shouldn’t ignore. This light typically means your brake pads are worn and need replacement. This article will guide you through the steps to reset the brake pad warning light on your BMW E36 after replacing the brake pads.
Understanding the E36 Brake Pad Warning Light
Your BMW E36 is equipped with a sensor that monitors the thickness of your brake pads. When the pads wear down to a certain point, this sensor triggers the brake pad warning light on your dashboard. It’s crucial to address this warning promptly, as driving with worn brake pads can significantly reduce your braking power and jeopardize your safety.
When to Reset the E36 Brake Pad Warning Light
It’s important to emphasize that you should only reset the brake pad warning light after you’ve replaced the worn brake pads with new ones. Attempting to reset the light without replacing the pads is not a solution and will only mask a potentially dangerous issue.

A Step-by-Step Guide to Resetting Your E36 Brake Pad Warning Light
Resetting the brake pad warning light on your E36 is a straightforward process. Here’s a step-by-step guide:
- Locate the brake pad wear sensor connector. This connector is usually located near the brake caliper on the wheel where you replaced the brake pads.
- Disconnect the sensor connector. Carefully unplug the connector from the sensor.
- Turn on the ignition. Turn your key to the second position (often labeled as position II), where the dashboard lights illuminate but without starting the engine.
- Short the connector terminals. Use a small piece of wire or a paperclip to bridge the two terminals inside the sensor connector.
- Observe the warning light. The brake pad warning light should flash, indicating the reset process is underway.
- Hold the connection. Keep the terminals connected until the warning light goes off completely. This may take several seconds.
- Disconnect the bridge. Remove the wire or paperclip connecting the connector terminals.
- Reconnect the sensor. Plug the sensor connector back into the brake pad sensor.
- Turn off the ignition. Switch off your car.
- Test your work. Turn the ignition back to position II and check if the brake pad warning light remains off.
