2022-2026 Audi Pre Sense Warning, Jolt, and Braking TSB

Owners of certain 2022-2026 Audi vehicles may experience unexpected interventions from their Audi pre sense system. This can manifest as an Audi pre sense warning, a warning jolt, or even automatic braking without an apparent immediate hazard. This Technical Service Bulletin (TSB 2058077/10) provides guidance for technicians to diagnose and explain these occurrences, which are often related to the system's intended functionality and limits.

Symptoms

Customers report experiencing unexpected Audi pre sense front interventions, which can include:

• An Audi pre sense warning appearing in the instrument cluster.
• An Audi pre sense warning jolt, a brief, noticeable application of the brakes.
• Unexpected partial braking.
• Unexpected emergency braking.

When these events occur, the Audi pre sense symbol typically appears in the instrument cluster, accompanied by an audible warning. However, hazard flashers or closed side windows are not activated simultaneously.

Diagnosis and Trigger Conditions

Diagnosing an Audi e-tron pre sense warning or similar issue often begins with a detailed interview with the customer. Technicians are instructed to ask specific questions about when the intervention occurred, whether the pre sense symbol was displayed, if a warning tone was issued, and if hazard lights or side windows were affected. It's noted that the concern might not be reproducible during a test drive.

The primary diagnostic step involves performing the Audi pre sense test program using the ODIS diagnostic system. This program is found 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 entering the date of the customer complaint and checks for pre sense interventions within a three-day window around that date.

Repair Procedure Summary

The TSB outlines a procedure based on the results of the ODIS test program. For most scenarios, the resolution involves explaining the operation and system limits of the Audi pre sense system to the customer, rather than a physical repair or software update. This includes:

• No Audi pre sense intervention: If the customer did not see the symbol, further analysis continues, but this TSB does not apply.
• Audi pre sense basic event: If the customer saw the symbol but no warning tone, the technician explains the system's operation and limits, referring to the owner's literature and self-study program SSP 662. Further analysis continues, but this TSB does not apply.
• Audi pre sense rear event: If radar sensors (e.g., lane change assist control unit J769) detected a potential rear impact, the technician explains the system's operation and limits, again referring to owner's literature. This TSB does not apply.
• Audi pre sense front warning: If the vehicle approached another vehicle in a critical situation, the instrument cluster provides visual and acoustic warnings. Technicians explain system limits and note MMI adjustment options (early/medium/late/off) that influence warning timing.
• Audi pre sense front warning jolt: If the driver didn't respond to warnings, the ABS control unit J104 issued a jolt to get attention. The technician explains the system's purpose.
• Audi pre sense front partial braking: If the driver applied brakes but not enough, Audi pre sense front provided additional braking assistance. The technician explains this function.
• Audi pre sense front emergency braking: If the driver failed to react, the ABS control unit J104 braked independently. If the customer feels the vehicle braked for no reason, technical support from the Technical Assistance Center (TAC) may be required.

This TSB is primarily informational, guiding technicians to educate owners about the sophisticated behavior of their vehicle's safety systems.

Owner Action

If you experience an Audi e-tron pre sense warning, warning jolt, or unexpected braking, especially if you believe the intervention was unwarranted, it is recommended to visit an authorized Audi dealership. The service technician will perform the Audi pre sense test program to investigate the event and provide an explanation of the system's functionality and limits. This TSB indicates that the primary action is often educational, ensuring owners understand how their advanced driver assistance systems operate.
