2024-2025 Audi Remote Start Anti-Theft Alarm Trigger TSB

Problem Overview

Owners of certain 2024-2025 Audi models equipped with remote start may encounter an unexpected issue: the vehicle's anti-theft alarm activates when the remote start function is used. This can be a frustrating experience, leading to unnecessary alarm sounds and potential confusion about the vehicle's security system. This specific problem, where the "anti-theft alarm is triggered when remote start is activated," is addressed by Audi Technical Service Bulletin (TSB) 96 24 13 2076057/1.

Affected Audi Models

This Technical Service Bulletin 2076057/1 applies to a wide range of 2024 and 2025 Audi models that are equipped with the remote start feature. This includes various body styles and trim levels across the A4, S4, A5, S5, RS 5, A6, S6, RS 6 Avant, A7, S7, RS 7, A8, S8, Q5, Q5 e quattro, SQ5, Q7, SQ7, Q8, SQ8, and RS Q8 lineups. The issue is specific to vehicles where remote start is installed.

Technical Background and Cause

The root cause of the anti-theft alarm triggering during remote start has been identified. When the remote start system is engaged, the vehicle's anti-theft alarm may be inadvertently activated by external devices. These devices are typically connected to the vehicle's On-Board Diagnostics (OBD) port. A common example cited in the TSB is an insurance tracker dongle, but other aftermarket accessories that plug into the OBD port could also cause this interference. These external connections can disrupt the normal communication within the vehicle's systems, leading to the false alarm.

Diagnosis and Reproducibility

For technicians, the complaint is readily reproducible. If a customer reports that their "anti-theft alarm is triggered when remote start is activated," the issue can typically be confirmed by simply attempting to use the remote start function while an external device is connected to the OBD port. The key diagnostic step is to identify and check for any such external devices at the OBD connection point.

Repair Procedure Summary

The resolution for this specific issue is straightforward and does not involve complex repairs or part replacements. The primary step outlined in Audi TSB 2076057/1 is to inspect the vehicle's OBD port for any connected external devices.

1. Locate the OBD Port: The OBD-II port is typically found under the dashboard on the driver's side, often near the steering column.
2. Check for External Devices: Visually inspect the port for any aftermarket devices plugged in, such as diagnostic tools, telematics units, or insurance monitoring dongles.
3. Remove Device(s): If an external device is found, carefully disconnect and remove it from the OBD port.
4. Retest Remote Start: After removing the device, attempt to use the remote start function again.
5. Verify Resolution: If the remote start now operates successfully without triggering the anti-theft alarm, the issue is considered resolved. No further analysis or repair work is required in such cases.
