how to address P0302 code on my Volkswagen Golf MK6 (2009-2014)?

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the negative terminal of the battery to ensure safety.
• Allow the engine to cool before beginning work.

2. Replace Spark Plug

• Remove the engine cover if necessary.
• Use a spark plug socket to remove the spark plug from cylinder 2.
• Inspect the old spark plug; replace it with a new one if worn or fouled.
• Torque the new spark plug to the manufacturer’s specifications (typically around 25 Nm).

3. Replace Ignition Coil

• Disconnect the electrical connector from the ignition coil for cylinder 2.
• Remove the bolts securing the ignition coil and lift it out.
• Install the new ignition coil, securing it with bolts to the specified torque.
• Reconnect the electrical connector.

4. Clean or Replace Fuel Injector

• If the injector is clogged, use a fuel injector cleaning kit to clean it, following the manufacturer’s instructions.
• If it is damaged, remove it by disconnecting the electrical connector and fuel line.
• Install the new fuel injector, ensuring it is properly seated and secured.

5. Inspect Wiring and Connectors

• Visually inspect the wiring and connectors for the ignition coil and fuel injector.
• Repair or replace any damaged wiring or connectors as necessary.

6. Perform Compression Test

• Reconnect the battery and ensure all components are securely in place.
• Perform a compression test on cylinder 2; if readings are low, further engine diagnostics may be needed.
