2026 Audi MQBevo Active Front Assist Intervention TSB

Important Workshop Information

Audi has issued Technical Service Bulletin (TSB) 2081074/1, titled "96 Driver assist systems: active front assist intervenes - MQBevo," to provide guidance for workshops. This bulletin is particularly relevant for vehicles still within their new model launch repair authorization period. For vehicles in this launch phase, workshops must create a case with the Technical Assistance Center (TAC) to obtain repair authorization, referencing TSB 2081074/1 in the first line of the TAC case.

Symptoms of Active Front Assist Intervening

Owners of 2026 Audi A3, S3, RS 3, and Q3 models may report the active front assist intervening during driving. This intervention is often accompanied by specific visual symbols on the instrument cluster. One symbol, depicting a car with a starburst in front, appears when actions such as a collision warning, brake jolt, automatic brake pressure increase, or automatic brake intervention are initiated. Another symbol, showing a car with an arrow swerving, appears when swerve support is active. It's important to note that workshop findings indicate no relevant diagnostic trouble codes (DTCs) are typically stored when the active front assist intervening occurs under these conditions.

Understanding Active Front Assist Interventions

The "Active front assist" system in your 2026 Audi MQBevo vehicle is designed with several intervention stages to enhance safety. Technicians use the ODIS-S diagnostic system to review the history of these interventions. Here’s a breakdown of what each intervention means:

• Preliminary Warning: If the system detects a possible collision risk, the driver receives a visual and acoustic warning to prompt a reaction.
• Main Warning: In situations with an immediate collision risk, the system issues an acute warning, often in the form of a short brake jolt. This prompts the driver to take evasive action or brake sharply.
• Reaction Time-Increasing Automatic Braking (RAB): This function initiates partial braking early to increase the time available before an impending collision. This gives the driver more time to react and reduces the speed of impact if a collision is unavoidable.
• Deescalating Automatic Braking (DAB): When a collision can only be avoided by immediate braking, the system performs automatic braking. This helps to prevent accidents or reduce their severity.
• Automatic Braking to a Stop (AFB): In critical situations, such as at intersections or when driving away from a standstill at low speeds, the vehicle is automatically braked to a complete stop. This prevents collisions with oncoming vehicles or pedestrians/cyclists.
• Driver-Triggered Controlled Braking (FZB): If the driver is braking but not sufficiently, the system increases the braking force to help avoid a collision. This assists drivers who may not brake hard enough in critical situations.
• Swerve Support (AWU): This corrective steering function assists the driver for a limited time when there is a risk of a frontal collision. If the driver initiates a clear steering movement, the system checks for sufficient space to swerve and provides steering assistance, potentially including targeted braking of individual wheels, to help avoid the collision. The driver can always override this assistance.

Diagnosis and Service Procedure

For technicians, the "Active front assist" test program within ODIS-S is used to access and display the intervention history. This program can be found by navigating through "Test plan > Select own test... > Diagnostic capable system > 0013 - Adaptive cruise control – J428 > 0013 - Technical Product Information > Active front assist."

When using the test program, technicians input the date of a suspected intervention. The system then checks for active front assist interventions that occurred three days before and three days after the entered date. The program generates a list of all interventions within this period, providing valuable diagnostic information for understanding why the 2026 Audi active front assist intervening.
