Solution

1. Preparation

Gather necessary tools: a clean rag or paper towel for wiping and a flashlight for better visibility.
Park the vehicle on a level surface and ensure the engine is turned off.

2. Locate the Brake Fluid Reservoir

Open the hood and secure it with the prop rod.
Identify the brake fluid reservoir, which is typically located near the back of the engine bay on the driver's side. It usually has a translucent plastic body.

3. Check Fluid Level

Inspect the fluid level through the side of the reservoir. It should be between the 'MIN' and 'MAX' markings.
If the fluid level is below the 'MIN' mark, brake fluid needs to be added.

4. Add Brake Fluid (if necessary)

Remove the reservoir cap by twisting it counterclockwise.
Using a funnel, add the recommended brake fluid (usually DOT 4 for Volkswagen vehicles) until it reaches the 'MAX' mark.
Avoid overfilling the reservoir as it can lead to brake system issues.

5. Secure the Reservoir

Replace the cap securely, ensuring it is tightened properly.
Close the hood and ensure it is latched.
