Solution

1. Preparation

Gather necessary tools: clean cloth or paper towels.
Ensure the vehicle is parked on a level surface.

2. Inspect the Brake Fluid Reservoir

Locate the Reservoir: Open the hood and identify the brake fluid reservoir, typically a translucent plastic container with a cap labeled "brake fluid."
Clean the Cap Area: Wipe down the area around the reservoir cap with a clean cloth to prevent dirt from entering when the cap is removed.

3. Check Fluid Level

Open the Cap: Carefully twist off the reservoir cap. Avoid spilling any fluid.
Check Level: Observe the fluid level against the minimum and maximum marks on the side of the reservoir.
Add Fluid if Necessary: If the level is below the minimum mark, add the appropriate brake fluid (DOT 4 is typically recommended for VW vehicles) until it reaches the maximum mark.

4. Secure the Reservoir

Replace the Cap: Ensure the cap is tightly secured after checking or adding fluid.
Clean Up: Dispose of any used materials and clean any spills immediately.
