Solution

1. Preparation

Gather necessary tools: a flashlight for better visibility.
Ensure the vehicle is parked safely and the engine is off.

2. Locate the Brake Fluid Reservoir

Open the hood by pulling the hood release lever inside the vehicle.
Secure the hood using the prop rod.
Identify the brake fluid reservoir, typically located near the back of the engine bay on the driver's side, marked with a cap labeled "Brake Fluid."

3. Inspect Fluid Level

Use the flashlight to clearly see the fluid level inside the reservoir.
Check against the "MIN" and "MAX" markings on the side of the reservoir.
If the fluid is below the "MIN" line, it needs to be refilled.

4. Check Fluid Condition

Inspect the brake fluid color; it should generally be clear to light amber.
If the fluid appears dark or contaminated, it may need to be replaced entirely.

5. Refill or Replace Brake Fluid (if necessary)

If the fluid level is low, remove the cap of the brake fluid reservoir.
Using a funnel, add the appropriate brake fluid (DOT 4 is commonly recommended for most Volkswagen models).
Fill to the "MAX" line, ensuring not to overfill.
Replace the cap securely.
