The Engine Fault Code P2007 refers to a problem with the intake manifold runner control system, specifically indicating that the runner is stuck in the closed position on Bank 2. This code is common in various vehicles, especially those with V-type engines that have multiple intake manifolds.
What It Means:
– Intake Manifold Runner Control (IMRC): This system helps optimize engine performance by adjusting the length of the intake runners. When the engine is at low RPMs, the runners can be shorter for better torque. At higher RPMs, they can be longer for better power.
– Stuck Closed: If the runner is stuck closed, it can restrict airflow into the engine, leading to poor performance, reduced fuel efficiency, and possibly triggering the check engine light.
Possible Causes:
1. Faulty IMRC Actuator: The actuator may be malfunctioning and not moving the runners.
2. Vacuum Leaks: Leaks in the vacuum system can prevent the actuator from working properly.
3. Electrical Issues: Damaged wiring or connectors related to the IMRC can cause this code.
4. Carbon Build-Up: Deposits in the intake manifold can cause the runners to stick.
5. Faulty Sensors: Related sensors that monitor the position of the runners may be defective.
Manufacturer Variations:
While P2007 generally means the same across many manufacturers, some brands may have specific interpretations or additional codes. Here are a few examples:
– Volkswagen/Audi: Similar code applies, but they may have additional codes for different bank issues.
– Mercedes-Benz: The code might be related to the MAF (Mass Air Flow) sensor or other intake issues.
– Porsche: Similar to Audi, but might also involve performance tuning aspects.
– Land Rover/Jaguar: These vehicles might also show related codes for their specific engine management systems.
If you encounter this code, its best to diagnose the specific vehicles system using a scan tool and follow the manufacturers service manual for troubleshooting. Addressing the underlying issue promptly can help maintain engine performance and efficiency.

– Mercedes: Mercedes vehicles may have additional sensors that monitor the IMRC system, which could also trigger this code if they fail.
– Audi: Audi models often have a dual-runner system, and if the control for Bank 2 fails, it may also affect performance in Bank 1.
– Jaguar: In Jaguars, the IMRC system may be integrated with other systems, leading to more complex diagnostics if the code appears.
– Land Rover: Land Rovers might have unique wiring harness issues that can lead to electrical failures in the IMRC system.
Diagnostic Steps:
1. Visual Inspection: Check for any visible damage to the IMRC actuator or wiring.
2. Scan for Codes: Use a diagnostic scanner to check for additional codes that may provide more context.
3. Test the Actuator: Apply direct power to the actuator to see if it operates correctly.
4. Check for Vacuum Leaks: Inspect hoses and connections for any leaks.
5. Clean the Intake Manifold: If carbon build-up is suspected, consider cleaning the intake manifold.
If you encounter this code, it`s best to take a systematic approach to diagnose the issue.
Fixing the Engine Fault Code P2007, which indicates that the intake manifold runner control is stuck closed on Bank 2, involves a few steps. This code can appear in various European cars like Audi, Porsche, Mercedes, and others, but the general approach is similar. Heres how you can tackle it:
Steps to Fix P2007:
1. Check the Code: Use an OBD-II scanner to confirm that P2007 is the only code present. If there are other codes, address those first.
2. Visual Inspection:
– Intake Manifold: Look for any visible damage or disconnections in the intake manifold.
– Vacuum Lines: Check for any cracked or disconnected vacuum hoses that could affect the runner control.
– Electrical Connections: Inspect the wiring and connectors going to the intake manifold runner control actuator for corrosion or damage.
3. Test the Actuator:
– The intake manifold runner control is usually operated by an electronic actuator. You can test this actuator with a multimeter to see if its functioning properly.
– If its not working, you may need to replace the actuator.
4. Clean the Intake Manifold:
– Carbon buildup can cause the runners to stick. Remove the intake manifold and clean it thoroughly, especially around the runner control area.
5. Check the Engine Control Unit (ECU):
– Sometimes, the issue could be related to the ECU not sending the right signals. If you suspect this, you may need to have the ECU checked or reprogrammed.
6. Clear the Code:
– After making repairs, clear the code using the OBD-II scanner and take the car for a test drive to see if the code returns.
Manufacturer-Specific Notes:
– Audi: On some Audi models, the intake manifold runner control might be part of a larger assembly, so ensure that youre replacing the correct component.
– Porsche: For Porsche vehicles, the process is similar, but always check for model-specific issues, as some models may have more complex intake systems.
– Mercedes: In Mercedes cars, the issue might be linked to the MAF (Mass Air Flow) sensor. Ensure its functioning correctly, as a faulty MAF can trigger similar codes.
– Mini: Mini vehicles may have a more compact engine bay, making access to the intake manifold more challenging. Be cautious when removing components to avoid breaking anything.
