Solution

1. Preparation

Gather necessary tools and materials.
Park the vehicle on a flat surface and engage the parking brake.
Allow the engine to cool completely before starting any work.

2. Inspect for Fluid Leaks

Tools Required: Oil catch pan, flashlight
Inspect under the vehicle for any signs of fluid pooling.
Identify the type of fluid (oil, coolant, brake fluid) based on color and consistency.
Clean any visible spills and determine the source of the leak.

3. Check and Replace Engine Oil

Tools Required: Socket set, oil filter wrench, oil catch pan, funnel
Drain the old oil using the oil catch pan and replace it with fresh oil of the correct specification (typically 5W-30 for the MK6).
Change the oil filter if it appears dirty or damaged.
Torque the oil drain plug to manufacturer specifications (usually around 25 Nm).

4. Inspect and Replace Coolant

Tools Required: Coolant tester, funnel
Check the coolant level in the reservoir; top off with the appropriate coolant if low.
Inspect the radiator and hoses for any signs of damage or leaks.
If necessary, flush the cooling system and fill with fresh coolant according to specifications.

5. Brake System Inspection

Tools Required: Jack, jack stands, lug wrench
Safely lift the vehicle and remove the wheels to access the brake components.
Inspect brake pads for excessive wear; replace if they appear burnt or thin.
Check for any signs of brake fluid leaks.
