Solution

1. Preparation

Tools Required: OBD-II scanner, jack and jack stands, socket set, torque wrench, fluid catch pan.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical shock or unintended engine start.

2. Inspect and Replace Drive Belts

Inspect the condition of the serpentine belt for cracks or fraying.
- If damaged, loosen the tensioner using a socket and remove the old belt.
- Install the new belt following the routing diagram located under the hood.
- Tighten the tensioner to the manufacturer's specifications.

3. Check Transmission Fluid

Remove the transmission fluid dipstick and check fluid level and color.
- If low, add the recommended transmission fluid type (usually VW-specific).
- If contaminated, drain the old fluid using a fluid catch pan, replace with new fluid, and check for leaks.

4. Inspect Wheel Bearings

Lift the vehicle with a jack and secure it on jack stands.
Spin each wheel by hand to listen for grinding or roughness.
- If noise is present, replace the affected wheel bearing following the vehicle service manual for proper disassembly and installation.

5. Reconnect Battery

Reconnect the battery terminals, ensuring they are secure.
Start the vehicle and listen for any remaining noises.
