If you’re experiencing steering issues in your MK6 Jetta, a faulty steering angle sensor might be the culprit. This guide outlines the steps to calibrate the steering angle sensor using VCDS (Vag-Com Diagnostic System) specifically for a MK6 Jetta, focusing on accessing module 44 – Steering Assist. You will need your 4-digit security access code for successful calibration.
Locating Module 44 – Steering Assist and Entering Security Access Code
Begin by connecting your VCDS interface to your vehicle’s OBD-II port and launching the VCDS software. Select “Select Control Module.” Then navigate to “44 – Steering Assistance.” You may encounter a request for a 4-digit security access code. You’ll need this code to proceed with any adaptations or basic settings. This code is vehicle specific. Online resources and forums dedicated to VW/Audi may assist in locating this code for your specific Jetta.
Performing Steering Angle Sensor Initialization and Calibration
Initialization:
- Drive and Straighten Wheel: Drive the vehicle slowly and find a safe location to park. Ensure the steering wheel is as centered as possible. With the engine running and the car in park, access module 44 – Steering Assistance.
- Access Basic Settings: Within module 44, navigate to “Basic Settings” and then select “Steering Angle Sensor (G85) Initialization.”
- Live Data Check (Optional): Before starting the initialization, it’s helpful to note the current steering angle sensor reading. Go to “Live Data” and find “Steering Angle Sensor (G85) – Angle.” This allows comparison after calibration. Note down the reading. Enter the security code when prompted.
Calibration:
- Initiate Calibration: In “Basic Settings,” select “Steering Angle Sensor (G85).” Start the calibration procedure. The procedure will guide you through turning the steering wheel.
- Steering Wheel Turns: Typically, the process involves turning the steering wheel to the extreme right, holding for 5 seconds, returning to center, then turning to the extreme left, holding for 5 seconds, and finally returning to the center and holding for 10 seconds. Follow the on-screen prompts precisely.
- Calibration Completion: After completing the sequence, wait for the system to confirm successful calibration. This may take a minute or two. Stop the calibration procedure using the “Stop” button.
Post-Calibration Procedures
- Power Cycle: Turn off the engine, remove the key, open and close the driver’s door. This completes a power cycle, allowing the system to reset.
- Fault Code Scan: Restart the engine. Scan for fault codes within module 44 and clear any existing faults related to the steering angle sensor.
- Steering Stop Calibration (if necessary): If your vehicle requires steering stop calibration, access “Basic Settings” in module 44. Select “Steering Angle Sensor Zero Calibration w/ Steer. Wheel Scales”. Follow on-screen prompts, turning the wheel left and right until audible beeps. Return to center. Stop the procedure and scan/clear any faults.
Verification and Final Steps
A successful calibration should resolve steering-related warning lights or messages on the dashboard. Test drive the vehicle to confirm proper steering functionality. If issues persist, recheck the procedure, ensuring all steps were followed correctly. If problems continue, consult a qualified automotive technician or specialized VW/Audi repair shop for further diagnosis. Addressing these issues promptly ensures safe and optimal vehicle performance.
