2025 Audi A5 Front Assist Intervention TSB 2076135/2

Audi has issued Technical Service Bulletin (TSB) 2076135/2 to address concerns regarding the active front assist system in certain 2025 Audi models. This bulletin provides guidance for technicians to diagnose and resolve issues where the system intervenes unexpectedly or malfunctions.

This TSB is particularly relevant for owners of 2025 Audi A5, Q5, S5, and SQ5 vehicles who may be experiencing problems with their driver assistance features, specifically the 2025 Audi A5 Front Assist intervention.

Symptoms of Front Assist Intervention Issues

Owners may notice various issues with their vehicle's active front assist system. The primary complaint often reported is that "The front assist is intervening" when it shouldn't, or not intervening when expected. This can manifest in several ways:

• Emergency Braking Functionality: The automatic emergency braking (Front Assist) or automatic partial braking (City-ANB) may activate too early, too late, or unintentionally. In some cases, the system might misfire, fail to deploy, or show no function at all.
• Incorrect Operation: The system might activate without cause, operate with an incorrect sequence, or be generally faulty.
• Warning Indicators: Drivers may see specific warning symbols on the instrument cluster or MMI. These include a "Front assist icon" (Figure 1 in the TSB) indicating collision warning, brake jolt, automatic brake pressure increase, or automatic brake intervention. A "Swerve assist activation icon" (Figure 2 in the TSB) may also appear if the swerve assist is active.

Understanding Front Assist Interventions

The TSB details various types of interventions and their explanations, which technicians use during diagnosis:

• Preliminary Warning: A visual and acoustic warning is issued if a possible collision risk is detected.
• Main Warning: An acute warning, often a short brake jolt, is given when there is an immediate collision risk, prompting the driver to take evasive action or brake hard.
• RAB (Reaction Time-Increasing Automatic Braking): This involves early partial braking to increase the driver's reaction time and reduce the impact speed in a potential collision.
• DAB (Deescalating Automatic Braking): Automatic braking is performed immediately in situations where a collision can only be avoided by rapid braking, helping to prevent or reduce accident severity.
• AFB (Automatic Braking to a Stop): In critical intersection scenarios, especially at low speeds or from a standstill, the vehicle is automatically braked to a stop to prevent collisions with other vehicles or pedestrians.
• FZB (Driver-Triggered Controlled Braking): This function increases the braking force applied by the driver if they are not braking sufficiently in critical situations.
• AWU (Swerve Support): A corrective steering function that assists the driver in performing an evasive maneuver when there is a risk of a frontal collision.
• ANA (Automatic Emergency Swerve): This is a corrective steering function that provides collision-avoiding steering intervention when a frontal collision risk is detected, helping the vehicle to perform an automatic evasive maneuver.

Diagnosis and Trigger Conditions

To diagnose the 2025 Audi A5 Front Assist intervention, technicians are instructed to use the
