The dreaded brake pad warning light on your E60’s dashboard. It’s an unwelcome sight for any BMW owner, but don’t panic. This article will guide you through understanding the warning, diagnosing the problem, and exploring your options for a fix.
Understanding the E60 Brake Pad Warning Light
Your E60 is equipped with a sophisticated sensor system designed to alert you of potential maintenance needs. The brake pad warning light, often a yellow circle with an exclamation mark inside parentheses, is triggered by one of two things:
- Worn Brake Pads: Your brake pads have worn down to a predetermined thickness, signaling it’s time for a replacement.
- Faulty Sensor: While less common, the sensor itself could be malfunctioning, triggering the warning light prematurely.
Diagnosing the Issue: Worn Pads or Faulty Sensor?
Before you order new brake pads, it’s crucial to determine if they are indeed the culprit. Here’s how:
-
Visually Inspect Your Brake Pads:
- Safely jack up your car and remove the wheel where you suspect pad wear.
- Examine the brake pad thickness through the inspection hole in the caliper.
- If you see less than 3mm of pad material, it’s time for new pads.

Use a Diagnostic Scanner (Advanced):
- Connect a compatible OBD-II scanner to your E60’s diagnostic port.
- Read the error codes related to the brake system.
- This will pinpoint the exact cause of the warning light, whether it’s worn pads, a faulty sensor, or another issue.
