how to address the P0302 code on my Volkswagen Golf Eighth Generation (2020-present)?

Solution

1. Preparation

• Gather tools and parts required for the repair.
• Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the battery to prevent electrical shocks.

2. Inspect and Replace Spark Plug

• Tools Required: Socket set, torque wrench, spark plug socket.
• Remove the engine cover if necessary.
• Locate the spark plug for cylinder 2 and remove the ignition coil by unscrewing it.
• Remove the spark plug using a spark plug socket.
• Inspect the spark plug for wear; replace if damaged or if the gap is incorrect.
• Install the new spark plug and torque to the manufacturer's specification (usually around 20 Nm).

3. Check and Replace Ignition Coil

• If the ignition coil appears damaged or the spark plug was replaced but the issue persists, replace the ignition coil for cylinder 2.
• Disconnect the electrical connector from the ignition coil and remove it.
• Install the new ignition coil and reconnect the electrical connector.

4. Inspect Fuel Injector

• If the misfire persists, check the fuel injector for cylinder 2.
• Remove the fuel rail and inspect the injector for clogs or leaks.
• Clean or replace the fuel injector as necessary.
• Reinstall the fuel rail ensuring proper sealing.

5. Reassemble and Test

• Reattach any components removed during the repair.
• Reconnect the battery and ensure all connections are secure.
• Start the engine and check for the check engine light.
