Solution

1. Preparation

Gather necessary tools and materials.
Tools Required: Clean rag, funnel (if adding fluid).
Safety Warnings: Ensure the vehicle is off and cool before working in the engine bay.

2. Check Fluid Level

Remove the cap of the brake fluid reservoir carefully, ensuring no dirt or debris enters the reservoir.
Use a clean rag to wipe any residue from the cap and around the opening to prevent contamination.
Visually check the fluid level against the "MIN" and "MAX" indicators on the side of the reservoir.

3. Add Brake Fluid (if necessary)

If the fluid level is below the "MIN" mark, add the appropriate brake fluid type (usually DOT 4 for Volkswagen).
Use a funnel to carefully pour in brake fluid to avoid spills.
Fill the reservoir to the "MAX" level, ensuring not to overfill.
Reinstall the reservoir cap securely.

4. Clean Up

Wipe any spilled brake fluid immediately, as it can damage vehicle paint and components.
Dispose of any waste properly and securely store the brake fluid.
