1. What is Audi DTC 00927:011?

Audi Dtc 00927:011 signals an “Open Circuit” within the Terminal 30 (Right) circuit, suggesting a break in the electrical connection. This fault code, stored in the Central Electronics module (J519), indicates that the control unit isn’t receiving the expected voltage from Terminal 30, the constant positive power supply which is crucial for various vehicle systems. The “Intermittent” descriptor means the issue isn’t constantly present, making diagnosis challenging.

• Terminal 30: This is a direct power supply from the battery, always on even when the ignition is off. It provides power to various control modules and systems, allowing them to retain memory and perform essential functions.
• Open Circuit: This indicates a break in the electrical path, preventing current flow. It could be due to a broken wire, a loose connection, a corroded terminal, or a faulty component within the circuit.
• Central Electronics Module (J519): This module controls various electrical functions in the vehicle, including lighting, wipers, and power distribution. It monitors the voltage and current flow in different circuits and stores diagnostic trouble codes (DTCs) when it detects a problem.

The intermittency of the fault suggests that the open circuit may be caused by vibration, temperature changes, or other factors that temporarily disrupt the electrical connection. Addressing this issue promptly is essential to prevent potential malfunctions and ensure the reliable operation of vehicle systems. AutoExplain.com offers remote support services to help diagnose and resolve such electrical issues efficiently.

2. What are the Symptoms of Audi DTC 00927:011?

The symptoms of Audi DTC 00927:011 can vary, but typically include electrical malfunctions and warning messages related to lighting and other systems, as the Central Electronics module relies on a stable power supply. These symptoms arise because Terminal 30 powers many essential functions, and an interruption can disrupt their operation.

Common symptoms include:

• Lighting Issues: Erratic behavior of lights, such as flickering, dimming, or failure to operate. This can affect headlights, turn signals, fog lights, and other exterior lights.
• Warning Messages: Display of warning messages on the dashboard related to lighting or other electrical systems. These messages might indicate a problem with a specific bulb or system.
• Inoperative Systems: Malfunctions in systems that rely on Terminal 30 for power, such as the wipers, power windows, or central locking.
• Battery Drain: In some cases, an open circuit can lead to parasitic battery drain, as the system attempts to compensate for the loss of power.
• Module Communication Issues: Some control modules may lose communication with the scan tool due to lack of power.
• Check Engine Light:Illumination of the check engine light (CEL) or malfunction indicator lamp (MIL) on the dashboard.

The intermittent nature of the fault can make these symptoms appear and disappear, making diagnosis more challenging. It’s important to address these symptoms promptly to prevent further damage and ensure the reliable operation of the vehicle. AutoExplain.com offers expert remote support to help diagnose and resolve intermittent electrical issues, ensuring your Audi functions correctly.
