why does my Volkswagen Golf MK7 (2015-2019) keep throwing a P0302 code?

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the battery to avoid electrical shorts.
• Ensure the engine is cool before starting work.

2. Replace Spark Plug

• Tools Required: Socket set, torque wrench, spark plug socket
• Remove the engine cover if applicable.
• Disconnect the ignition coil connector.
• Unbolt and remove the ignition coil from cylinder 2.
• Remove the old spark plug using a spark plug socket.
• Install the new spark plug, tightening it to the manufacturer's torque specification (typically around 15-20 lb-ft).
• Reinstall the ignition coil and reconnect the connector.

3. Test and Replace Ignition Coil (if necessary)

• Tools Required: Multimeter, socket set
• If the spark plug was in good condition, test the ignition coil with a multimeter for resistance according to specifications.
• If the coil is faulty, remove it and replace it with a new one.
• Reinstall and reconnect everything properly.

4. Inspect and Replace Fuel Injector (if necessary)

• Tools Required: Fuel line disconnect tool, socket set
• If issues persist, inspect the fuel injector for cylinder 2.
• If the injector is clogged or faulty, replace it with a new one following the manufacturer's instructions.
• Reconnect all connections and ensure no leaks are present.
