how to fix P0301 code in Skoda Octavia NFL (2020-Present)

Solution

1. Preparation

• Gather tools and parts needed.
• Disconnect the battery to prevent electrical short circuits.
• Allow the engine to cool down before starting work.

2. Replace Spark Plug

• Remove the engine cover if applicable.
• Locate the spark plug for cylinder 1 (usually near the front of the engine).
• Use a spark plug socket and ratchet to remove the old spark plug.
• Inspect the old spark plug for wear or damage.
• Apply anti-seize compound to the threads of the new spark plug.
• Torque the new spark plug to the manufacturer’s specification (usually around 15-20 Nm).
• Reinstall the engine cover.

3. Replace Ignition Coil

• Disconnect the electrical connector from the ignition coil for cylinder 1.
• Remove the mounting bolts using a socket set.
• Carefully lift out the ignition coil.
• Install the new ignition coil and secure it with the mounting bolts.
• Reconnect the electrical connector.

4. Inspect and Clean Fuel Injector

• Disconnect the fuel injector connector for cylinder 1.
• Use an appropriate tool to remove the fuel rail if necessary.
• Inspect the fuel injector for blockages; clean if needed or replace if faulty.
• Reinstall the fuel injector and reconnect the fuel rail and connector.

5. Perform Compression Test

• Remove the spark plug from cylinder 1.
• Insert the compression gauge into the spark plug hole.
• Crank the engine for a few seconds and record the compression reading.
• Compare the reading with the manufacturer’s specifications (typically around 200 psi).
• If compression is low, further investigation into internal engine components may be required.
