Audi DTC 01309:013 signifies “Power Steering Control Module: No Signal/Communication.” This diagnostic trouble code (DTC) indicates a lack of communication between the power steering control module and other modules within the vehicle’s network, such as the central electronics module or the instrument cluster. The root cause may be a faulty module, wiring issues, or network problems.

1.1. Common Symptoms Associated with DTC 01309:013

Several symptoms can indicate that your Audi is experiencing a DTC 01309:013 error. Recognizing these signs early can help in diagnosing the problem quickly.

• Loss of Power Steering Assist: The most noticeable symptom is the complete absence of power steering, making the steering wheel hard to turn, especially at low speeds.
• Power Steering Warning Light: A solid red power steering warning light on the dashboard is a clear indicator of a problem.
• Difficulty Steering: Maneuvering the vehicle becomes challenging, increasing the risk of accidents, especially when parking or making sharp turns.
• Error Codes on Scan: When scanned with an OBD-II scanner, the code 01309 will appear, often in multiple modules like the central electronics, ABS, or instrument cluster.
• Intermittent Issues: Sometimes, the issue might appear and disappear, making diagnosis trickier. This intermittency suggests a loose connection or a failing component.

1.2. What Are the Potential Causes of the 01309:013 Error?

Understanding the possible causes of the 01309:013 error is crucial for effective troubleshooting. Here are the primary reasons:

• Faulty Power Steering Control Module: The module itself might be defective due to internal component failure.
• Wiring Issues: Damaged, corroded, or loose wiring and connectors can disrupt communication. This includes ground connections, power supply wires, and CAN bus wires.
• CAN Bus Problems: Issues with the Controller Area Network (CAN) bus, which is the vehicle’s communication network, can prevent the power steering module from communicating with other systems.
• Blown Fuses: A blown fuse in the power steering system can cut off power to the module.
• Low Battery Voltage: Insufficient voltage can cause modules to malfunction or fail to communicate properly.
• Software Issues: Corrupted or outdated software in the power steering control module can lead to communication errors.
• Grounding Problems: Poor or corroded ground connections can cause a variety of electrical issues, including communication faults.
• Related Module Faults: Sometimes, a fault in another module can indirectly affect the power steering system.

2. Step-by-Step Diagnostic Procedure for Audi DTC 01309:013

Diagnosing the Audi DTC 01309:013 requires a systematic approach to identify the root cause of the communication failure. Here’s a detailed procedure:

2.1. Initial Inspection

Start with a thorough visual inspection.

• Check the Battery: Ensure the battery is in good condition and fully charged. Low voltage can cause communication issues.
• Inspect Fuses: Verify that all fuses related to the power steering system are intact. Refer to your vehicle’s fuse diagram for locations.
• Examine Wiring and Connectors: Look for any signs of damage, corrosion, or loose connections in the wiring harness and connectors associated with the power steering control module. Pay special attention to ground connections.

2.2. Scan for Diagnostic Trouble Codes

Use an OBD-II scanner to read and record all DTCs present in the vehicle’s system.

• Record All Codes: Note down all the codes, not just the 01309:013. Other codes might provide additional clues.
• Clear Codes and Retest: Clear the codes and take the vehicle for a short test drive. Rescan to see which codes reappear. This helps identify persistent issues.

2.3. Power Steering Control Module Inspection

Focus on the power steering control module and its connections.

• Locate the Module: Find the power steering control module. Its location varies depending on the Audi model but is often near the steering rack or under the dashboard.
• Check Module Connections: Ensure all connectors are firmly attached to the module. Clean any corrosion and apply dielectric grease.
• Inspect Module Wiring: Check the wiring harness leading to the module for damage, cuts, or wear.

2.4. Testing the CAN Bus

The Controller Area Network (CAN) bus is crucial for communication between modules.

• CAN Bus Voltage Check: Use a multimeter to check the voltage on the CAN high and CAN low wires. The voltage should be within the specified range (typically around 2.5V).
• CAN Bus Resistance Check: With the vehicle off, measure the resistance between the CAN high and CAN low wires. It should be around 60 ohms. Deviations from this value indicate a problem with the CAN bus.

2.5. Advanced Diagnostics with Specialized Tools

For deeper analysis, use advanced diagnostic tools.

• Oscilloscope Testing: Use an oscilloscope to analyze the CAN bus signal waveforms. This can reveal issues like signal interference or missing data packets.
• Module-Specific Scanners: Use a scanner that can communicate directly with the power steering control module. This allows you to read module-specific data and perform diagnostic tests.

3. Solutions for Resolving Audi DTC 01309:013

Once you’ve identified the cause of the 01309:013 error, you can implement the appropriate solution. Here are several options:

3.1. Repairing or Replacing Wiring and Connectors

If damaged wiring or corroded connectors are the cause:
