Volkswagen Golf Seventh Generation (2013-2020) brake light is on what could it mean

Solution

1. Preparation

• Gather necessary tools and parts.
• Park the vehicle on a level surface and engage the parking brake.
• Disconnect the negative terminal of the battery to ensure safety while working on the vehicle.

2. Check Brake Fluid Level

• Inspect the brake fluid reservoir for the fluid level; it should be within the recommended range.
• If low, top up with the appropriate brake fluid (usually DOT 4 for Volkswagen).
• If the fluid is low, check for leaks in the brake lines, calipers, and master cylinder.

3. Inspect Brake Components

• Remove the wheel to access brake pads and rotors.
• Examine the brake pads for thickness; replace if worn down to below 3mm.
• Inspect the brake rotors for scoring, warping, or damage; replace if necessary.
• Reassemble the wheel after inspection or replacement.

4. Check Brake Light Switch

• Locate the brake light switch on the brake pedal assembly.
• Disconnect the wiring harness and test the switch with a multimeter; it should show continuity when the pedal is pressed.
• Replace the brake light switch if faulty.

5. Reconnect Battery and Test

• Reconnect the negative battery terminal.
• Start the vehicle and press the brake pedal to check if the brake light is still illuminated.
