2023-2026 Audi Pre Sense Warning and Braking TSB

Audi has released Technical Service Bulletin (TSB) 2058077/8 to address concerns regarding unexpected Audi pre sense front interventions. This TSB, issued on November 15, 2023, supersedes an earlier bulletin, Group 90 number 23-31 dated July 19, 2023. It provides guidance for diagnosing situations where the pre sense system issues warnings, causes jolts, or engages brakes without an apparent reason.

This TSB applies to a wide range of 2017-2026 Audi models, including the 2023-2026 Audi e-tron, and is crucial for technicians to properly assess and explain the behavior of the pre sense system to vehicle owners.

Symptoms

Owners of affected Audi vehicles, including the 2023-2026 Audi e-tron, may experience one or more of the following unexpected Audi pre sense front interventions:

• An "Audi pre sense front warning" is displayed.
• An "Audi pre sense front warning jolt" occurs.
• "Audi pre sense front partial braking" is initiated.
• "Audi pre sense emergency braking" is activated.

During these events, the "Audi pre sense symbol" may appear in the instrument cluster, accompanied by an audible warning. Notably, neither the hazard flashers nor the side windows are activated simultaneously.

Diagnosis and Trigger Conditions

When a customer reports an unexpected Audi pre sense front intervention, technicians are instructed to perform the Audi pre sense test program. This program is accessed via the ODIS diagnostic system under:

• Test plan > Select self-test > Diagnostic capable system > 00A5 - Front sensors for driver assistant systems > 00A5 - 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 Audi pre sense front interventions that occurred within a three-day window before and after the entered date. The program provides a list of any detected pre sense events during this period.

Based on the results of the ODIS test program, specific actions are recommended:

• If no Audi pre sense intervention was experienced by the customer: The customer did not see the "Audi pre sense symbol" in the instrument cluster. The TSB does not apply, and further analysis should continue.
• If an Audi pre sense basic event occurred: The customer saw the "Audi pre sense symbol" but a warning tone did not sound. Technicians should explain the operation and system limits of Audi pre sense basic to the customer.
• If an Audi pre sense rear event occurred: This involves the radar sensors of the lane change assist system. Technicians should explain the operation and system limits of Audi pre sense rear to the customer.
• If an Audi pre sense front warning occurred: This happens when the vehicle approaches another vehicle critically. Technicians should explain the operation and system limits of Audi pre sense front and note the MMI adjustment options (early/medium/late/off) that influence warning timing.
• If an Audi pre sense front warning jolt occurred: The ABS control unit J104 issues an urgent warning jolt if the driver doesn't respond to warnings. Technicians should explain the operation and system limits of Audi pre sense city and Audi pre sense front.
• If Audi pre sense front partial braking occurred: This happens when the system increases braking performance if the driver's braking is insufficient to prevent a collision. Technicians should explain that the system provided additional braking assistance.
• If Audi pre sense front emergency braking occurred: If the driver fails to react, the ABS control unit J104 brakes the vehicle independently. If the customer feels the vehicle braked for no reason, the Technical Assistance Center (TAC) should be contacted.

Important Warnings

• Please note that only a limited number of events are stored for each category.
• The Audi pre sense test program must only be performed once per complaint. As an exception to this, if the customer specifies several times when the complaint occurred, the Audi pre sense test program may be performed a maximum of three times for the complaint.
• If the vehicle is outside any warranty, this Technical Service Bulletin is informational only.

Warranty Information

This TSB outlines specific warranty claim details for technicians:

• Claim Type: 110 up to 48 Months/50,000 Miles.
• CPO Covered Vehicles: G10 for CPO Covered Vehicles – Verify Owner.
• Service Number: 9163
• Damage Code: 0039
• Diagnostic Time: GFF (0150 0000), with time stated on the diagnostic protocol (Max 100 TU).
• Road test prior to the service procedure: No allowance (0 TU).
• Road test after the service procedure: No allowance (0 TU).
