why is my Volkswagen Golf Eighth Generation (2020-present) making a whistling noise when driving

Solution

1. Preparation

• Gather the necessary tools and parts.
• Park the vehicle on a level surface and engage the parking brake.
• Disconnect the negative battery terminal to prevent electrical issues.

2. Inspect the Air Intake System

• Remove the engine cover (if applicable) using a socket set.
• Visually inspect the air intake hose for cracks or loose clamps.
• Tighten any loose connections and replace the hose if damaged.

3. Check Engine Bay Hoses

• Inspect all vacuum and PCV hoses for wear or disconnections.
• Replace any damaged hoses with OEM parts to ensure proper fit and function.

4. Examine the Exhaust System

• Check the exhaust pipes, muffler, and catalytic converter for any signs of leaks.
• Use exhaust tape or replace sections of the exhaust if leaks are found.

5. Finalizing Repairs

• Reconnect the negative battery terminal.
• Start the engine and listen for any remaining noises.
• Ensure all components are secure and properly installed.
