Some VW Golf models are equipped with electronic parking brakes. Problems within the electronic parking brake system, such as a faulty switch or sensor, can activate the brake warning light.
Diagnosing the Problem
Determining the exact cause of the brake warning light often requires specialized diagnostic equipment. Here are some general guidelines:
- Check Brake Fluid: If the brake fluid level is low, inspect for leaks and top it up. However, this might indicate a more serious problem requiring professional attention.
- Inspect Brake Pads: If you are comfortable with basic car maintenance, you can visually check the thickness of your brake pads.
- Consult Your VW Golf Manual: Your owner’s manual provides specific information about warning lights and recommended actions.
- Seek Professional Help: If you are unsure about any aspect of your braking system, it is crucial to seek professional diagnosis and repair from a qualified mechanic specializing in VW vehicles.
