Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, screwdrivers, multimeter, brake fluid.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect Brake Fluid Level

Locate the brake fluid reservoir under the hood.
Remove the cap and visually inspect the fluid level.
If low, add the recommended type of brake fluid (usually DOT 4 for Volkswagen).
Recheck the parking brake light after topping off.

3. Test the Parking Brake Switch

Locate the parking brake switch under the center console.
Disconnect the wiring harness from the switch.
Use a multimeter to test for continuity when the switch is engaged (lever pulled).
If the switch is faulty, replace it with a new part.

4. Check Parking Brake Cables

Inspect the parking brake cables for fraying, kinking, or corrosion.
If damaged, remove the cables from their anchor points and replace with new cables.
Ensure proper routing and tension when reinstalling.

5. Reassemble and Reconnect

Reconnect the battery terminal after all checks and repairs.
Test the parking brake by engaging and disengaging it several times.
Ensure the parking brake light turns off when the brake is released.
