Common Causes of the BMW Parking Brake Warning Light
Low Brake Fluid
One of the most common culprits is low brake fluid. Your BMW’s braking system relies on hydraulic pressure, and insufficient fluid can trigger the warning light. Check your brake fluid reservoir and top it off if necessary. If the fluid level drops rapidly, you likely have a leak requiring professional attention.
Faulty Parking Brake Switch
The parking brake switch itself can malfunction, sending incorrect signals to the car’s computer. This can cause the warning light to illuminate even when the parking brake is disengaged. A faulty switch usually needs replacement.
Worn Brake Pads
Worn brake pads can sometimes trigger the parking brake warning light, especially if they’re excessively worn. Thin brake pads can cause the brake caliper pistons to extend further, potentially impacting the brake fluid level and triggering the warning system.
Troubleshooting the BMW Parking Brake Warning Light
Check the Parking Brake Lever
First, ensure the parking brake is fully released. Sometimes, the lever might not be completely disengaged, causing the light to stay on. Give it a firm push down to ensure it’s fully released.
Inspect the Brake Fluid Reservoir
Check the brake fluid level in the reservoir. If it’s low, add the recommended brake fluid for your BMW model. Remember, consistently low fluid suggests a leak, which needs immediate professional inspection.
