2021-2022 Audi Dynamic Steering G85 Calibration TSB

Symptoms

Owners of 2021-2022 Audi A4, A5, A6, and A7 models equipped with dynamic steering may not experience direct customer concerns related to the steering angle sender G85. Instead, this issue is typically identified by technicians during pre-delivery inspection (PDI) or other diagnostic work.

The primary symptoms observed by workshop technicians include situations where the "steering angle sender G85 cannot be calibrated" or the steering system's "end stops are not or cannot be adapted."

Associated Control Modules and Address Words

When the dynamic steering angle sender G85 requires new adaptation, multiple Diagnostic Trouble Codes (DTCs) may be found across various control modules. These modules and their associated address words are crucial for diagnosis:

• ABS control module (ESC): J104 (address word 0003)
• Steering system: J500 (address word 0044)
• Suspension control module: J775 (address word 0074)
• Instrument cluster: J285 (address word 0017)

For vehicles equipped with dynamic steering (PR Code 1N7 or 1N8), the G85 adaptation function is specifically found under address word 001B within the dynamic steering control module, J792. For other vehicles, G85 adaptation can be found under address word 0003 (ABS control module, J104) or address word 0044 (power steering control module, J500).

Diagnosis and Trigger Conditions

The need for a new adaptation of the G85 steering angle sender is often triggered by the presence of multiple DTCs within the control modules listed above. Technicians will typically discover that the steering angle sender G85 cannot be calibrated or its end stops cannot be adapted during routine diagnostic procedures or vehicle preparation.

Repair Procedure Summary

To resolve the issue of the Audi dynamic steering G85 calibration, technicians must proceed with the G85 calibration using the Offboard Diagnostic Information System (ODIS). This involves connecting the vehicle to the ODIS system and following the guided functions to perform the necessary calibration steps for the steering angle sender.
