2025 Audi A5/S5 Electric Steering Column Adjustment Issue

Owners of certain 2025 Audi A5 and S5 vehicles may experience problems with their electric steering column adjustment. Audi has issued Technical Service Bulletin (TSB) 2079458/1 to address these concerns, providing a specific procedure for technicians to resolve the issue without replacing components.

This TSB, released for publishing on September 29, 2025, highlights that the problem primarily affects new vehicles or those with low mileage. The core of the issue stems from the electric steering column not being fully or correctly adapted during a specific production period. This bulletin applies to 2025 Audi A5 models with chassis numbers from 000001 to 053781, specifically those with PR numbers 2C7 and 4UT.

Symptoms of Electric Steering Column Malfunction

Owners may notice several issues related to the electric steering column adjustment. These symptoms indicate that the 2025 Audi A5 electric steering column is not functioning as intended. Common complaints include:

• "Steering column adjustment does not work": The electric steering column may not respond to adjustment commands at all.
• "Steering column only moves briefly or with a delay": The column might move for a short period or after a noticeable delay, failing to complete the desired adjustment.
• "Steering column does not move to the end stops": The steering column may not reach its fully extended or retracted positions.

Workshop diagnostics may identify these issues through specific complaint types related to the steering wheel adjustment control module, such as:

• "chassis -> steering, steering assist -> steering column power height adjustment functionality -> no function"
• "chassis -> steering, steering assist -> power steering column forward/back adjuster functionality -> no function"
• "chassis -> steering, steering assist -> steering column power height adjustment functionality -> operation sequence incorrect"
• "chassis -> steering, steering assist -> power steering column forward/back adjuster functionality -> cannot be switched on/activated"
• "chassis -> steering -> steering wheel adjustment control module functionality -> no function"
• "chassis -> steering -> steering wheel adjustment control module functionality -> partially out of order"
• "chassis -> steering -> steering wheel adjustment control module functionality -> operation sequence incorrect"

Technical Background

Audi's workshop findings confirm that the reported complaints can be consistently reproduced and are directly attributable to the electric steering column adjustment system. The technical background provided in TSB 2079458/1 explains that during a certain production period, the electric steering column may not have been adapted fully or at all. This condition is specifically noted to occur in new vehicles or vehicles with low mileage. A production solution has been implemented for vehicles manufactured from July 2025 onwards.

Important Warnings and Documentation Requirements

Audi explicitly states a critical instruction for technicians regarding this issue:

• "Do not replace any components. Instead, re-adapt the electric steering column adjustment."

This warning is crucial for owners, as it indicates that the problem is typically a software or calibration issue, not a hardware failure. Attempting to replace parts unnecessarily would not resolve the underlying condition and could lead to unwarranted repair costs if not covered under warranty.

For billing purposes, technicians are required to attach a video clearly showing the complaint to DOC-IT. This video must include the VIN and date, must not be edited, and should be in focus with sufficient light. High resolution is not necessary. It is also important to mark the location of the problem and ensure the video documentation does not show any people, faces, license plates, or customer data.

Repair Procedure: Re-adaptation

The primary solution outlined in TSB 2079458/1 is to re-adapt the electric steering column. This procedure can be performed using two methods:

With a Diagnostic Tester

For workshops equipped with a diagnostic tester, technicians should follow the instructions provided within the Guided Function. This method ensures a systematic and precise re-adaptation process.

Without a Diagnostic Tester

If a diagnostic tester is not available, a manual re-adaptation routine can be performed using the steering column adjustment buttons. The TSB includes a diagram illustrating four positions for the adjustment buttons: position 1 (forwards), position 2 (upwards), position 3 (backwards), and position 4 (downwards). The routine involves a specific sequence of button presses:

1. Press the button back 3 times in succession (towards the driver, corresponding to position 3).
2. Press the button forwards once (towards the front of the vehicle, corresponding to position 1).
3. Press the button back once (towards the driver, corresponding to position 3).
4. Press the button upwards once (towards the headliner, corresponding to position 2).
5. Press the button downwards once (towards the floor mat, corresponding to position 4).

This sequence helps recalibrate the steering column's movement range and functionality, resolving the 2025 Audi A5 electric steering column issue.
