2021 Audi Steering Column Adjustment Not Working TSB

Owners of certain 2021 Audi models, including the Audi e-tron, may experience issues with their electric steering column adjustment not working in the vertical direction. This problem is often indicated by the storage of Diagnostic Trouble Code (DTC) B14BF01 in the vehicle's electronic central control module (BCM 1, J519).

This Technical Service Bulletin (TSB) 2062288/3, superseding bulletin 21-95, outlines the necessary steps for technicians to diagnose and resolve the issue, primarily through a software update and a specific calibration process for the electric steering column.

Symptoms

Owners may notice that the electric steering column adjustment is not functioning as expected. Specifically, the steering column may fail to move in the vertical direction when the adjustment switch is operated.

Fault Codes / DTCs

When the electric steering column adjustment issue occurs, the following diagnostic trouble code may be stored:

Code	Description	Module	Symptom Code
B14BF01	Steering column vertical adjustment motor electrical error	BCM 1 (J519, address word 0009)	66145

Repair Procedure Summary

Addressing the faulty electric steering column adjustment involves a two-part process: a software update and a physical calibration. The first step requires updating the steering column control module, J866, using the Software Version Management (SVM) system.

Technicians must follow the instructions in TSB 2011732, "00 Software Version Management (SVM), operating instructions." The SVM update involves specific old and new software part numbers and versions, along with an SVM Code Input of 649S001 for applicable models. This ensures the control module has the latest programming to prevent the Audi e-tron steering column adjustment issue.

After the software update, the function of the electric steering column adjustment must be restored. This involves a manual procedure where a force of approximately 40 kg (88 lbs) is applied to push the steering wheel upward, while simultaneously pressing the steering column adjustment switch upwards. This action helps to re-establish the basic function.

Finally, the electric steering column adjustment must be cleared by performing up to 50 adjustment cycles in the vertical direction. This step requires a specialized tool kit, T10230, which weighs about 9 kg (20 lbs). The tool kit is attached to the steering wheel to create a current in the adjustment motor, allowing the unit to clear itself. Technicians are advised to protect the vehicle's seat with plastic foil and ensure the driver's seat is moved fully back and the steering wheel towards the dashboard before starting this process.

Required Tools or Parts

To perform the clearing procedure for the electric steering column adjustment, a specific tool is required:

• T10230: An assembly tool designed to simulate the necessary weight (approximately 9 kg or 20 lbs) to create current in the adjustment motor during the calibration cycles.
