why does my Volkswagen Golf MK7 (2015-2019) smell like gas inside

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a flat surface and the engine is cool.
• Disconnect the battery to prevent any electrical hazards.

2. Inspect and Replace Fuel Filler Cap

• Remove the fuel filler cap and inspect for any damage or wear.
• If damaged, replace with a new fuel filler cap.
• Reattach the new cap securely.

3. Inspect and Replace Damaged Fuel Lines

• Locate the fuel lines running from the fuel tank to the engine.
• If any cracks or wear are observed, use a socket set to disconnect the fuel lines.
• Replace damaged fuel lines with new, OEM-spec lines.
• Reconnect the lines, ensuring all connections are secure.

4. Test and Replace Fuel Injectors (if necessary)

• If fuel injectors are suspected to be leaking, remove them by detaching the electrical connectors and unscrewing them from the intake manifold.
• Inspect the O-rings for damage.
• Replace any damaged injectors with new OEM injectors.
• Reinstall the injectors securely and reconnect electrical connectors.

5. Final Inspection and Reconnect Battery

• Check all replaced parts for proper installation.
• Reconnect the battery.
• Start the engine and check for any signs of leaks or abnormal smells.
