1. What Does VCDS 01044 Mean and How Do I Fix It?

The VCDS error code 01044 typically indicates an issue with the steering assist system, often related to incorrect coding or adaptation. Addressing this problem involves using VCDS (VAG-COM Diagnostic System) to properly recode or adapt the steering assist module. This may require resetting the steering angle sensor or performing a basic settings adaptation.

• In-depth Explanation: The VCDS 01044 code can arise from several scenarios, including replacing the steering angle sensor, updating the ECU software, or inadvertently corrupting the existing coding. Ross-Tech’s forums often discuss various troubleshooting steps and specific adaptation procedures relevant to different vehicle models. The root cause is often a discrepancy between the expected and actual steering angle, leading the system to trigger the fault code.

1.1 Why Does Error 01044 Occur?

Error 01044 can occur due to several reasons, including:

• Incorrect Coding: The steering assist module has been incorrectly coded, which can happen after an ECU update or when swapping components.
• Adaptation Issues: The steering angle sensor adaptation is not correctly set, preventing the system from accurately determining the steering wheel position.
• Component Replacement: A faulty or replaced steering angle sensor requires proper adaptation to the vehicle.
• Software Glitches: Temporary software glitches can sometimes trigger this error, which can be resolved with a reset or recalibration.

1.2 How to Fix Error 01044 Using VCDS

Fixing error 01044 typically involves these steps:

1. Connect VCDS: Connect your VCDS cable to the vehicle and start the software.
2. Select Control Module: Go to the “Select Control Module” option.
3. Access Steering Assist: Choose “44 – Steering Assist”.
4. Check Fault Codes: Read the fault codes to confirm the presence of the 01044 error.
5. Clear Fault Codes: Clear the fault codes and see if the error returns immediately.
6. Perform Basic Settings: If the error persists, perform a basic setting adaptation:
   • Go to “Basic Settings – 04”.
   • Enter the appropriate group number (usually 060 or 001, depending on the vehicle model).
   • Follow the on-screen instructions to complete the adaptation.
7. Steering Angle Sensor (SAS) Calibration: If required, calibrate the SAS. This usually involves driving the vehicle straight for a short distance to allow the system to learn the center position.
8. Recheck Fault Codes: After the adaptation, recheck the fault codes to ensure the error has been resolved.
9. Road Test: Perform a road test to confirm that the steering assist system is functioning correctly.

1.3 Common Mistakes to Avoid When Fixing Error 01044

Several common mistakes can hinder the resolution of error 01044:

• Ignoring Ross-Tech Wiki: Ross-Tech’s wiki (http://wiki.ross-tech.com/wiki/index.php/VWGolf(1K)_Steering_Assist) provides detailed procedures for various models. Failing to consult this resource can lead to incorrect adaptation attempts.
• Incorrect Group Number: Using the wrong group number in Basic Settings can cause further issues. Always verify the correct group number for your specific vehicle model.
• Skipping SAS Calibration: Failing to calibrate the Steering Angle Sensor after adaptation can result in the error code reappearing.
• Using Incorrect Security Access Codes: Some procedures require specific security access codes. Using the wrong code can lock the module or cause irreversible damage.
