Understanding Your Jetta’s Brake Warning System

Common Causes of a Brake Warning Light
There are several reasons why your Volkswagen Jetta’s brake warning light might be on. Some common culprits include:

- Faulty Brake Sensor: Sometimes, the brake pad wear sensor itself can malfunction, triggering the light even when the brake pads are fine.
- ABS Issues: If the Anti-lock Braking System (ABS) detects a problem, it can also illuminate the brake warning light. This usually requires specialized diagnostic equipment.
- Parking Brake Engaged: It may seem obvious, but sometimes the parking brake is simply engaged. Make sure to check this first.
Diagnosing the Problem: From DIY to Professional Help

If it’s low, top it off with the correct type of brake fluid specified in your owner’s manual.
