Solution

1. Preparation

Gather tools: clean cloth, flashlight.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear gloves to maintain cleanliness.

2. Locate the Brake Fluid Reservoir

Identify the brake fluid reservoir, typically a translucent plastic container.
Use the flashlight if visibility is poor to get a clear view.

3. Check Brake Fluid Level

Inspect the fluid level against the minimum and maximum markings.
If the fluid is below the minimum line, it requires topping up.

4. Top Up Brake Fluid (if necessary)

Remove the cap of the brake fluid reservoir carefully.
Use a funnel to avoid spills, and add the appropriate type of brake fluid (usually DOT 4 for Volkswagen).
Fill until the fluid reaches the maximum line, but do not overfill.

5. Reassemble

Replace the cap securely on the brake fluid reservoir.
Close the hood of the vehicle.
