my Skoda Octavia NFL (2020-Present) has poor fuel economy, what could be the reason?

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a flat surface.
• Disconnect the battery to prevent any electrical issues during the repair.

2. Inspect and Replace Air Filter

• Tools Required: Screwdriver, replacement air filter
• Remove the air filter cover by unscrewing the fasteners.
• Take out the old air filter and inspect it for dirt and damage.
• Install the new air filter, ensuring it fits snugly into the housing.
• Reattach the air filter cover and secure it with the fasteners.

3. Clean or Replace Fuel Injectors

• Tools Required: Fuel injector cleaning kit or replacement injectors
• Disconnect the fuel lines from the injectors (ensure to relieve fuel pressure beforehand).
• If cleaning, follow the instructions on the cleaning kit to flush the injectors.
• If replacing, remove the old injectors from the rail and install the new ones, ensuring proper sealing.
• Reconnect the fuel lines and check for leaks before proceeding.

4. Check for Vacuum Leaks

• Tools Required: Smoke machine or soapy water solution
• Use a smoke machine to introduce smoke into the intake system; look for any smoke escaping from hoses or gaskets.
• If using soapy water, spray potential leak areas and look for bubbling.
• Replace any damaged hoses or gaskets as necessary.

5. Tire Pressure and Condition Check

• Tools Required: Tire pressure gauge
• Use a tire pressure gauge to check each tire's pressure against manufacturer specifications.
• Inflate tires to the recommended pressure if they are low.
• Inspect the tread for wear; replace tires if they are excessively worn.
