Audi A5 (8T) Active Steering

This page applies to Address 1B-Active Steering in Audi models such as the A4 (8K), A5 (8T), Q5 (8R) in addition to the newer A6/A7/A8 (4G/4H) models with J792 Component: DYNAMIKLENK.

Active/Dynamic Steering is NOT standard equipment in all of the models listed above. This equipment can be identified using PR Codes such as 1N7 - Dynamic steering or by evaluating the data in the Auto-Scan:

Address 1B: Active Steering (J792)
  Part No SW: 4H0 907 144 C    HW: 4H0 907 144 C
  Component: DYNAMIKLENK.  H06 0100

Address 1B: Active Steering (J792)
  Part No SW: 8K0 907 144 A    HW: 8K0 907 144 A
  Component: DYNAMIKLENK.  H05 0322

Coding

Coding for this Control Module is normally done via Software Version Management (SVM). If the old Control Module is still accessible read/copy it's Coding to the new Module. A Security Access code is required prior to Coding.

Security Access

• 61378 Coding and Basic Setting enabling

Basic Setting

Prerequisites:

• Battery Voltage is 12.0V+
  
• Key ON, Engine at idle
• No fault codes other than 01087 - Basic Setting Not Performed
  
• Perform G85-Steering Angle Sensor Basic Settings. One the following pages would apply:
  • 2008+ A4, A5 and Q5 Steering Angle Sensor (G85) Calibration
  • 2011+ A6, A7 and A8 Steering Angle Sensor (G85) Calibration

Continue Only after successfully completing the G85 basic settings above

• Leave the steering wheel in the straight ahead position during the next steps (Tolerance: ±1.5 °).

[Select]
[1B-Active Steering]
[Security Access - 16]
Enter 61378, to enable the basic setting.
[Do it!]

[Basic Settings - 04]
Group 101
[Go!]
[ON/OFF/Next]

• Basic Settings is active.
  • If "No Value" is shown in the 4th field turn the steering wheel at a rate lower than 50°/s in excess of 45° using both directions until OK is shown.
  • If "OK" was shown in the 4th field continue.

[Done, Go Back]
[Fault Codes - 02]
Check and clear fault codes.Cycle the ignition to confirm the controller is fault free.
[Close Controller, Go Back - 06]

Special Notes

Replacement of the 1B-Active Steering (J792) control module requires Online Coding and Parameterization using SVM (Software Version Management). SVM is a system used by VW/Audi to flash update control modules, and in certain cases, to change their Coding, Adaptation and configure Parameters. VCDS cannot perform SVM. NAR (North American Region) market TPI 2029594 may be helpful if coding is not possible when attempting to code a replacement module on the dealer level.
