2025-2026 Audi Active Front Assist Intervention TSB

Audi has issued Technical Service Bulletin (TSB) 2076135/6 to address instances where the active front assist system may intervene unexpectedly in certain 2025-2026 Audi models. This TSB provides guidance for technicians on diagnosing the intervention history and outlines a software update to improve the system's performance and prevent unwanted Audi active front assist intervention.

Symptoms of Active Front Assist Intervention

Owners may notice the following symptoms indicating an Audi active front assist intervention:

• A general feeling that "The front assist is intervening."
• A specific "Front assist icon displayed on the instrument cluster or the MMI."
• A "Swerve assist activation icon" may also appear if swerve assist is active.

These interventions can manifest as several actions initiated by the system:

• "Collision warning."
• "Brake jolt."
• "Automatic brake pressure increase."
• "Automatic brake intervention."

The TSB further details various types of interventions that may occur:

• Preliminary warning: A visual and acoustic warning if a possible collision risk is detected.
• Main warning: An acute warning, often a short brake jolt, when there is an immediate collision risk.
• Reaction time-increasing automatic braking (RAB): Early partial braking to give the driver more time to react and reduce impact speed.
• Deescalating automatic braking (DAB): Immediate automatic braking to avoid accidents or reduce their severity.
• Automatic braking to a stop (AFB): Braking to a full stop in critical situations, such as at intersections, to prevent collisions with oncoming vehicles or pedestrians.
• Driver-triggered controlled braking (FZB): Increases braking force when the driver is not braking sufficiently in critical situations.
• Swerve support (AWU): Corrective steering assistance to help avoid frontal collisions by swerving, potentially including targeted braking of individual wheels.
• Automatic emergency swerve (ANA): Similar to swerve support, this function performs an automatic evasive maneuver, including steering intervention and targeted braking, to avoid frontal collisions.

Diagnosis and Trigger Conditions

To diagnose the issue, technicians will use the ODIS-S diagnostic system. They will access the "Active front assist" test program to review the intervention history. This program is found under the diagnostic path: Test plan > Select self-test > Diagnostic capable system > 00A5 - Front sensors for driver assistant systems - R242 > 00A5 - Technical Service Bulletin (TSB) > Active front assist.

The test program allows technicians to enter a date and check for active front assist interventions that occurred within a three-day window before and after the specified date. This helps identify patterns and confirm the Audi active front assist intervention events.

Repair Procedure Summary

The primary repair involves a combined software update, identified as 03.10.00/C (28.13.01) KD2. This update is designed to increase the robustness of the active front assist function. It is applicable to vehicles currently running software versions SW0250 or SW0295.

The software update procedure, referenced in TSB 2079690, includes connecting a battery charger to maintain stable voltage during the flash process. Technicians will perform Guided Functions (GFF) and ensure all required preliminary and follow-up work is completed, including any necessary calibration drives.

Required Tools or Parts

• ODIS-S diagnostic system: Essential for running the "Active front assist" test program and performing the software update.
• Battery charger: Required to maintain vehicle battery voltage during the software flash process.

Important Warnings

Owners should be aware of the following:

• "If the vehicle is outside of any warranty, this Technical Service Bulletin is informational only." This means that repairs for vehicles not under warranty may incur charges.
• All warranty claims must adhere to the Audi Warranty Policies and Procedures Manual and are subject to review by Audi Warranty.

Owner Action

If you are experiencing unexpected Audi active front assist intervention or any of the described symptoms, it is recommended to schedule an appointment with an authorized Audi dealer. They can perform the necessary diagnostic checks using the ODIS-S system and apply the software update (TSB 2076135/6 and TSB 2079690) if your vehicle is affected and qualifies for warranty coverage.
