One of the most valuable tools in an automotive technician’s arsenal is a diagnostic scanner. These devices grant us a window into the intricate workings of a vehicle’s computer system, allowing us to pinpoint issues that would be nearly impossible to diagnose otherwise. One such issue is represented by the VCDS error code 00907.
What Does VCDS Error Code 00907 Mean?
In simple terms, error code 00907 in a VCDS system typically indicates a problem with the fuel pressure sensor (G247). This sensor plays a critical role in monitoring the pressure of the fuel being delivered to the engine. When the sensor sends a signal that falls outside the expected range, the ECU logs the 00907 error code.

Common Causes of Error Code 00907
Before we delve into solutions, it’s important to understand the common culprits behind this error code:
- Faulty Fuel Pressure Sensor (G247): The most likely cause, a malfunctioning sensor can send inaccurate readings.
- Wiring Issues: Damaged, corroded, or loose wiring between the sensor and the ECU can disrupt signal transmission.
- Fuel Pump Problems: A failing fuel pump might not provide adequate pressure.
- Clogged Fuel Filter: A restricted fuel filter can also lead to low fuel pressure.

“A thorough diagnosis is crucial before replacing any parts,” cautions automotive electronics expert Robert Thompson in his book “Modern Automotive Diagnostics.” “Often, a simple wiring issue is mistaken for a component failure.”
Troubleshooting and Fixing Error Code 00907
Here’s a step-by-step approach to diagnosing and addressing error code 00907:
-
Read the Codes: Begin by connecting your VCDS system to the vehicle’s diagnostic port and retrieving any stored error codes.
-
Inspect the Fuel Pressure Sensor: Visually check the sensor for any signs of damage, loose connections, or corrosion.
-
Check Fuel Pressure: Using a mechanical gauge, verify the actual fuel pressure against the manufacturer’s specifications. This step helps confirm if the sensor’s readings are accurate.
-
Test Wiring and Connections: Carefully examine the wiring harness leading to the sensor for any breaks, frays, or loose connections.
-
Inspect the Fuel System: Check the fuel pump, filter, and lines for any obstructions or malfunctions that could impact fuel pressure.
Important Notes:
- When working around the fuel system, take necessary safety precautions to prevent fire hazards.
- If you are not comfortable performing these diagnostic steps, it’s best to consult a qualified automotive technician.
