2022-2025 Audi A3 / S3 / RS 3 Pre Sense Warning TSB

Owners of 2022-2025 Audi A3, S3, and RS 3 models may experience unexpected interventions from the Audi pre sense front safety system. These interventions can include warnings, jolts, or even emergency braking when there is no apparent obstacle or reason for the system to activate. This issue, often difficult to reproduce during a test drive, is addressed by Audi Technical Service Bulletin (TSB) 90 23 54 2069662/2.

This TSB, issued on November 15, 2023, supersedes an earlier bulletin, 90 23-12, dated March 8, 2023. It provides guidance for technicians to properly diagnose and document these intermittent pre sense activations.

Symptoms

Owners typically report one or more of the following symptoms related to the Audi pre sense front system:

• "Audi pre sense front warning": The vehicle displays a visual warning on the instrument cluster, often accompanied by a red Audi pre sense symbol, and may issue an acoustic warning tone.
• "Audi pre sense front warning jolt": The ABS control unit J104 applies a short, noticeable brake application, intended to alert the driver to a potential hazard.
• "Audi pre sense front emergency braking": The vehicle initiates braking or increases braking performance, even when the driver perceives no immediate danger.

An "Audi pre sense" message may also appear on the instrument cluster, as shown in Figure 1 of the TSB. These interventions can occur without any preceding event or apparent cause.

Diagnostic Procedure

Since the 2025 Audi S3 pre sense warning and related issues are often intermittent and hard to reproduce, technicians are instructed to follow a specific diagnostic process:

1. Customer Interview: Technicians must ask the customer detailed questions, including:

   • When did the Audi pre sense front intervention take place (date and time)?
   • Was the red Audi pre sense symbol displayed in the instrument cluster during the event?
   • Was a warning tone issued simultaneously?
   • Were the hazard warning lights switched on or the side windows closed at the time of the intervention?

2. Audi pre sense test program: A specialized diagnostic test program is available to check for past pre sense interventions. This program can be accessed via the vehicle's diagnostic system under:

   • Test plan > Select self-test > Body > Electrical system > 01 - On Board Diagnostic capable systems > 0013 - Control Module for Adaptive Cruise Control -J428- > 0013 - Technical Service Bulletin (TSB) > Audi pre sense

   The test program requires the technician to input the date of the customer's complaint. It then checks for any Audi pre sense front interventions that occurred within a three-day window before and after the entered date. The program will provide a list of any recorded interventions.

Important Warnings for Owners and Technicians

Audi emphasizes specific guidelines for using the diagnostic test program:

• The Audi pre sense test program should only be performed once per complaint.
• However, if a customer reports multiple instances of the complaint, the test program may be performed a maximum of three times for that specific complaint.

This ensures that the diagnostic process is followed consistently and efficiently.
