The Engine Fault Code P2308 refers to an issue with the ignition coil, specifically for the `C` cylinder, in the secondary circuit. This code typically indicates that there is a problem with the ignition coil`s ability to produce a spark for that particular cylinder, which can lead to poor engine performance, misfires, or increased emissions.
Here are some common interpretations and possible causes for P2308:
1. Ignition Coil Failure: The ignition coil for cylinder C may be faulty or damaged.
2. Wiring Issues: There could be a problem with the wiring or connectors leading to the ignition coil, such as frayed wires or poor connections.
3. Power Supply Problems: The ignition coil might not be receiving the proper voltage or current due to issues in the electrical system.
4. ECU Issues: The Engine Control Unit (ECU) may be malfunctioning, leading to incorrect signals being sent to the ignition coil.
5. Spark Plug Issues: A worn or fouled spark plug can also cause misfires and may trigger this code.
Manufacturer-Specific Meanings:
While P2308 generally has the same meaning across many manufacturers, some brands may have unique interpretations or additional codes related to the issue. Here are a few examples:
– Porsche: May link this code to specific ignition coil issues in models like the 911 or Cayenne.

The Engine Fault Code P2308 refers to an issue with the ignition coil, specifically the secondary circuit for `Ignition Coil C.` This code can show up in various European vehicles, including Porsche, Mini, Mercedes, Audi, Jaguar, and Land Rover. Here are some common causes and possible differences among manufacturers:
Common Causes:
1. Faulty Ignition Coil: The ignition coil itself might be damaged or malfunctioning, leading to poor performance.
2. Wiring Issues: Damaged or corroded wires in the ignition coil circuit can disrupt the signal, causing the code to trigger.
3. Bad Spark Plug: A worn or damaged spark plug can affect the ignition process and lead to this fault code.
4. Poor Ground Connection: A weak or broken ground connection can prevent the ignition coil from functioning properly.
5. ECU Issues: The Engine Control Unit (ECU) might have a fault, affecting how it communicates with the ignition coil.
Manufacturer-Specific Differences:
– Porsche: In some Porsche models, the issue could also relate to the advanced ignition timing settings, which may need calibration.
– Mini: Mini vehicles may have specific connectors or wiring harness issues that are unique due to their compact design.
– Mercedes: Mercedes models might require a more detailed diagnostic to check for issues in the CAN bus system that could affect multiple coils.
– Audi: Audi vehicles often have a more complex ignition system, and the fault may arise from a failure in the coil driver circuit within the ECU.
– Jaguar: In some Jaguars, the fault may stem from a software issue that requires an update to the ECU.
– Land Rover: Land Rover vehicles may have additional components, like the ignition amplifier, that could also cause this code if they fail.
Diagnosing the exact cause of P2308 requires a thorough inspection of the ignition system, including the coils, wiring, and ECU. Always consult a professional or use a diagnostic tool for accurate troubleshooting.
The Engine Fault Code P2308 refers to an issue with the ignition coil, specifically the secondary circuit of ignition coil C. This can happen in various European cars, including Porsche, Mini, Mercedes, Audi, Jaguar, and Land Rover. Heres a general guide to help you troubleshoot and fix this issue:
Steps to Fix P2308 Ignition Coil C Secondary Circuit
1. Check the Ignition Coil:
– Inspect the ignition coil for any visible damage or corrosion. If it looks damaged, replace it.
– Make sure that the coil is properly connected to the wiring harness.
2. Test the Ignition Coil:
– Use a multimeter to check the resistance of the ignition coil. Compare your readings with the specifications in the vehicle`s repair manual.
– If the resistance is out of range, replace the ignition coil.
3. Inspect Wiring and Connectors:
– Look for damaged wires or loose connections in the secondary circuit.
– Repair or replace any damaged wiring or connectors.
4. Check the Spark Plug:
– Remove the spark plug associated with the faulty coil. Inspect it for wear or damage.
– Replace the spark plug if it looks worn out.
5. Test the Power Supply:
– Verify that the ignition coil is receiving power. Use a multimeter to check the voltage at the ignition coil connector.
– If theres no power, trace back to the ignition switch or fuse box.
6. Scan for Other Codes:
– Use an OBD-II scanner to check for any other fault codes that may be related. Address any additional issues.
7. Clear the Codes:
– After making repairs, clear the fault codes using an OBD-II scanner and take the car for a test drive to see if the code returns.
Manufacturer-Specific Considerations
– Porsche: Check if the ignition coil is part of a larger coil pack. If so, consider replacing the entire pack.
– Mini: Some Mini models have specific ignition coil configurations. Consult the owners manual for specific coil locations.
– Mercedes: Mercedes vehicles may have a different wiring layout. Always refer to the vehicle-specific wiring diagram.
– Audi: Audi models often have multiple ignition coils. If one is faulty, consider replacing all coils for better performance.
– Jaguar: Check for software updates or recalls related to the ignition system, as these can sometimes resolve underlying issues.
– Land Rover: Be aware that Land Rover models may have unique diagnostic procedures. Use the manufacturers specific tools if available.
Conclusion
Fixing the P2308 code involves checking the ignition coil, wiring, and related components. Always refer to your vehicles specific manual for details, as some steps may vary by manufacturer and model. If you`re unsure or the problem persists, its best to consult a professional mechanic.
Driving with a P2308 code, which indicates a problem with the ignition coil C secondary circuit, is not ideal. This code suggests there is a malfunction in the ignition system, specifically with the ignition coil that fires a particular cylinder. Heres what you should consider:
