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.
• NAR (North American Region) market TPI 2026507 pertains to DTCs 03221 Safety Lock for Active Steering: Mechanical Failure and 02538 Function Restriction due to Overload. The problem is a faulty steering column lock magnet and a repair kit is available for some models. After the steering column repair kit is installed the software level must be updated via SVM to a level greater than 0580 in the A4 (8K), A5 (8T) and Q5 (8R) chassis. At the time of publication the A6/A7/A8 (4G/4H) models did not require a flash update. Make sure to check the Factory Level Repair Manual for the vehicle in question.
  • RoW TPI 2028500 mentions the DTC 02538 in conjunction with specific Freeze Frame details and vehicle production dates to confirm if the document is applicable. When applicable, replacement of the1B-Active Steering (J792) module (instead of flash updating) is mentioned.
