what does code P0302 mean for my Volkswagen Golf MK7.5 (2020-Present)?

Solution

1. Preparation

• Gather tools and parts required for repair.
• Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Spark Plug

1. Remove the engine cover (if applicable) to access the spark plug.
2. Use a socket wrench to remove the spark plug from cylinder 2.
3. Inspect the spark plug for fouling or damage and replace if necessary.
4. Install the new spark plug and torque to the manufacturer's specification (typically around 15-20 lb-ft).

3. Check and Replace Ignition Coil

1. Disconnect the electrical connector from the ignition coil on cylinder 2.
2. Remove the ignition coil using a socket wrench.
3. Inspect the ignition coil for signs of damage or wear.
4. If needed, install a new ignition coil and reconnect the electrical connector.

4. Inspect Fuel Injector

1. Remove the fuel rail (if necessary) to access the injector for cylinder 2.
2. Inspect the injector for clogs or damage. Clean or replace as needed.
3. Reinstall the fuel rail and ensure all connections are secure.

5. Compression Test

1. Remove the spark plug from cylinder 2 and insert a compression gauge.
2. Crank the engine a few times to get a reading.
3. Compare the compression reading to the manufacturer specifications (generally around 150-200 psi).
4. If low compression is detected, further investigation into the engine internals may be necessary.
