Understanding Your BMW 118d Brake Pad Warning Light

Diagnosing the Problem: Is it Really the Brake Pads?
Sometimes, the bmw 118d brake pad warning light can be triggered by issues other than worn brake pads. A faulty sensor, damaged wiring, or even a low brake fluid level can be the culprit. So, before rushing to replace your brake pads, it’s crucial to diagnose the problem accurately.
Checking Your Brake Pads
Visually inspect your brake pads. If they are less than 3mm thick, it’s time for replacements.
Brake Pad Sensor Issues
The brake pad wear sensor is a small wire embedded in the brake pad. When the pad wears down, the sensor makes contact with the rotor, triggering the warning light. Sometimes, this sensor can malfunction or become damaged.
“A common misconception is that the light always means your pads are completely gone. Often, it’s a faulty sensor that needs replacing,” says automotive expert, Dr. Michael Schmidt, specializing in BMW diagnostics.
Brake Fluid Level and Other Potential Causes
Low brake fluid can also trigger the warning light. Check your brake fluid reservoir and top it off if necessary. However, consistently low brake fluid may indicate a leak, which requires immediate professional attention.
