VCDS error code 00907 typically relates to an issue with the fuel pump relay or its associated circuitry. This can manifest in various ways, from intermittent starting problems to complete engine failure. Understanding this code and its potential causes is crucial for efficient diagnostics and repair. 00907 vcds
What Does VCDS 00907 Mean?
The 00907 fault code, as diagnosed by the VCDS (Vag-Com Diagnostic System), specifically points towards a malfunction within the fuel pump relay control circuit. This relay is responsible for supplying power to the fuel pump, which delivers fuel from the tank to the engine. A faulty relay or related wiring can disrupt this process, leading to fuel starvation and engine performance issues.
Common Symptoms Associated with 00907
Symptoms of a 00907 fault code can vary, but often include:
- Difficulty starting the engine
- Engine stalling
- Loss of power
- Intermittent engine cut-outs
- No-start condition
These symptoms can be intermittent or constant, depending on the severity of the issue.
Diagnosing VCDS Fault Code 00907
Diagnosing 00907 requires a systematic approach to pinpoint the root cause. Begin by checking the fuel pump relay itself. A visual inspection for signs of damage or corrosion is essential. Next, test the relay’s functionality using a multimeter. If the relay is faulty, replacing it is a straightforward solution.
Checking the Wiring and Fuse
If the relay appears functional, the issue likely lies within the wiring or the fuse protecting the fuel pump circuit. Carefully examine the wiring harness for any breaks, shorts, or loose connections. A blown fuse can also cause this error code, so be sure to check and replace it if necessary.

“A common oversight is neglecting the fuse. Always check the fuse associated with the fuel pump relay before delving into more complex diagnostics,” says automotive electrical specialist, John Miller.
Resolving 00907: Step-by-Step Guide
- Connect the VCDS system to the vehicle’s diagnostic port.
- Read the fault codes and confirm the presence of 00907.
- Locate the fuel pump relay and visually inspect it.
- Test the relay using a multimeter. Replace if faulty.
- Check the fuse protecting the fuel pump circuit. Replace if blown.
- Inspect the wiring harness for any damage or loose connections. Repair as needed.
- Clear the fault codes and test the vehicle.
Beyond the Basics: Further Diagnostic Steps
If the basic checks don’t resolve the issue, further diagnostics may be required. This could involve checking the fuel pump itself, the ECU (Engine Control Unit), or other related components. 00907 vcds
VCDS 00907 Fuel Pump Testing
“Intermittent issues can be challenging. Using a fuel pressure gauge to monitor fuel pressure during operation can help identify intermittent fuel delivery problems,” advises Sarah Chen, a veteran automotive diagnostic technician.
Conclusion
The VCDS error code 00907 indicates a problem with the fuel pump relay circuit. By systematically checking the relay, fuse, and wiring, you can often pinpoint and resolve the issue quickly. However, more complex diagnostics might be necessary in some cases. Addressing this code promptly is crucial to maintain reliable engine performance and avoid potential breakdowns. Understanding and resolving this common VCDS code empowers car owners and technicians alike to effectively troubleshoot and maintain their vehicles.
