Engine Fault Code P0247

Turbocharger/Supercharger Wastegate Solenoid B

Care Engine Code Reader
The Engine Fault Code P0247 refers to an issue with the Turbocharger or Supercharger Wastegate Solenoid B. This solenoid controls the wastegate, which helps regulate the boost pressure in turbocharged or supercharged engines. When this code appears, it usually means theres a problem with the wastegate solenoid or the circuit connected to it.

Heres a breakdown of what it might mean:

1. Faulty Wastegate Solenoid: The solenoid itself may be malfunctioning, preventing it from opening or closing properly.

2. Wiring Issues: There could be damaged or corroded wires in the solenoid circuit, leading to poor connectivity.

3. Connector Problems: Loose or damaged connectors can interrupt the signal to the solenoid.

4. Vacuum Leaks: If there are leaks in the vacuum lines that control the wastegate, it can affect performance.

5. Turbocharger Issues: Problems with the turbocharger itself can also trigger this code.

6. ECU Problems: In rare cases, the Engine Control Unit (ECU) might have a fault that impacts the solenoid`s operation.

Manufacturer-Specific Meanings

While P0247 generally indicates a similar issue across many manufacturers, there can be slight variations in meaning or related symptoms. Here are a few examples:

– Volkswagen/Audi: The code might relate specifically to the N75 valve, which is a common component in their turbo systems.
Mercedes-Benz: Similar issues may be reflected in codes related to boost pressure control, but they may have additional codes for specific solenoids.
Porsche: In some cases, it could indicate a need for more detailed diagnostics on the turbo system, especially in performance models.
– Land Rover/Jaguar: These brands may have additional complexity due to their unique turbo systems, leading to different related codes.

If you see P0247, it`s a good idea to check the solenoid, wiring, and any related components to diagnose the issue accurately.
The Engine Fault Code P0247 indicates a problem with the turbocharger or supercharger wastegate solenoid B. This solenoid controls the wastegate, which regulates the boost pressure in the turbocharger or supercharger. Here are some common causes for this code:

1. Faulty Wastegate Solenoid: The solenoid itself may be defective, causing it to not open or close properly.

2. Wiring Issues: Damaged or corroded wiring or connectors leading to the wastegate solenoid can disrupt its function.

3. Vacuum Leaks: If there`s a vacuum leak in the system, it can affect the operation of the wastegate.

4. Faulty Turbocharger/Supercharger: The turbocharger or supercharger itself might have issues, such as a stuck wastegate.

5. Control Module Problems: The engine control module (ECM) may have a fault that affects the solenoid`s operation.

6. Boost Pressure Issues: Abnormal boost pressure readings can trigger this code, indicating a problem with the forced induction system.

7. Other Engine Faults: Sometimes, other related engine issues can cause this code to appear, as the system may be unable to regulate boost correctly.

Manufacturer-Specific Considerations:
Porsche: Check for specific software updates or recalls related to the turbo system.
Mini: Look for issues with the turbo`s wastegate actuator, which can be a common problem.
Mercedes: Pay attention to the M276 engine series, as they may have unique solenoid wiring issues.
Audi: Some models may have a secondary air injection system that can affect wastegate operation.
Jaguar: Ensure that the turbocharger is properly lubricated, as oil flow issues can affect the wastegate.
Land Rover: Check for known issues with the turbo system, particularly in models with the 3.0L supercharged engine.

When diagnosing P0247, it`s essential to consider these factors and check the vehicle`s specific service manual for additional insights.
The Engine Fault Code P0247 indicates a problem with the turbocharger or supercharger wastegate solenoid B. This can affect how your engine performs, especially in European cars like Porsche, Mini, Mercedes, Audi, Jaguar, and Land Rover. Heres how to troubleshoot and fix this issue:

Step-by-Step Fix:

1. Check for Other Codes: Before diving into repairs, use an OBD-II scanner to check for any other trouble codes. Sometimes, multiple issues can trigger the same symptoms.

2. Inspect the Wiring and Connectors:
– Look for damaged, frayed, or corroded wires connected to the wastegate solenoid.
– Ensure the connectors are secure and free of dirt or debris.

3. Test the Wastegate Solenoid:
– Disconnect the solenoid from the electrical connector.
– Use a multimeter to check the resistance across the solenoid terminals. Compare this with the manufacturers specifications.
– If the resistance is out of range, replace the solenoid.

4. Check for Vacuum Leaks:
– Inspect the vacuum lines connected to the wastegate. Cracks or leaks can affect performance.
– If you find any leaks, replace the damaged sections.

5. Inspect the Turbocharger:
– Check the turbocharger for any signs of damage or wear.
– Ensure that the wastegate actuator is moving freely. If its stuck, it may need lubrication or replacement.

6. Clear the Codes: After making repairs, use the OBD-II scanner to clear the fault codes and take the car for a test drive to see if the code returns.

Manufacturer-Specific Notes:

Porsche: For models like the 911 or Cayenne, ensure that the solenoid is correctly calibrated as per the service manual. They may have specific testing procedures.

Mini: Some Mini models may have a different wastegate setup. Refer to the Mini service manual for specific solenoid locations.

Mercedes: Mercedes vehicles often have multiple wastegate solenoids. Make sure youre testing the correct one (usually labeled in the service manual).

Audi: Audi models may have a more complex turbo system. If the solenoid replacement doesnt fix the issue, check the ECU for software updates or faults.

Jaguar: For Jaguar, ensure that the wastegate actuator is functioning properly, as some models have electronic actuators.

Land Rover: In Land Rover vehicles, check the air intake system for blockages that might affect turbo performance.

Final Thoughts:
If you`ve checked all of these components and the code still returns, it might be best to consult a professional mechanic. They can perform more advanced diagnostics and repairs.
Driving with a P0247 code, which indicates a problem with the turbocharger or supercharger wastegate solenoid B, can be risky. Heres a breakdown of what it means and how it might affect your vehicle:

General Implications:
1. Loss of Power: The wastegate controls the boost pressure from the turbocharger. If its malfunctioning, your car may not perform well, leading to a noticeable loss of power.
2. Engine Damage: In some cases, driving with this code can cause excessive boost pressure, which could lead to engine damage over time.
3. Fuel Efficiency: You may experience decreased fuel efficiency, as the engine may not be operating optimally.

Manufacturer-Specific Considerations:
Porsche: Driving may lead to reduced performance, but the car will likely enter a `limp mode` to protect the engine. It`s best to get it checked soon.
Mini: Similar to Porsche, expect a loss of power and potentially poor fuel economy. It`s advisable to address the issue quickly.
Mercedes: Mercedes vehicles often have sophisticated engine management systems that may compensate for the issue temporarily, but its still not safe to ignore the code for long.
Audi: Like other brands, you could experience reduced performance. Audi`s systems may also trigger a limp mode, which limits speed and power.
Jaguar: Jaguars might show performance issues, but they often have a robust engine management system that could prevent severe damage for a short time.
Land Rover: Expect a significant drop in power and possibly issues with off-road capabilities. Its recommended to address the problem as soon as possible.


While it might be possible to drive for a short time with a P0247 code, its not safe or advisable to ignore it. The best course of action is to have your vehicle diagnosed and repaired by a qualified mechanic to avoid further damage and ensure safe driving.
