Understanding Your E90 Brake Warning Light
The e90 brake warning light is designed to alert you to potential problems within your braking system. It’s a safety feature, not something to be ignored. The light itself can manifest in different ways, from a constant glow to an intermittent flicker. Understanding these variations can provide clues to the underlying issue.
Common Causes of an Illuminated E90 Brake Warning Light
Several factors can trigger the e90 brake warning light. These include:
- Worn Brake Pads: This is the most common culprit. As your brake pads wear down, a sensor triggers the warning light.
- Low Brake Fluid: Low brake fluid can indicate a leak in the system, which needs immediate attention.
- Faulty Brake Sensor: Sometimes, the sensor itself can malfunction, triggering the light even if the brake pads and fluid levels are fine.
- ABS Issues: Problems with the Anti-lock Braking System (ABS) can also illuminate the brake warning light.
- Parking Brake Engaged: While seemingly obvious, it’s easy to overlook. Make sure the parking brake is fully released.

Before rushing to a mechanic, there are a few things you can check yourself. Start with the easiest checks first and proceed to more complex ones.

- Inspect Brake Fluid Level: Open the hood and locate the brake fluid reservoir. Check the fluid level against the minimum and maximum markings.
- Visually Inspect Brake Pads: If you’re comfortable doing so, check the thickness of your brake pads through the wheel spokes. If they appear thin, they likely need replacing.
