2025 Audi A5/S5 Convenience Close Function TSB 2079931/1

Audi has issued Technical Service Bulletin (TSB) 2079931/1, released on November 10, 2025, to address a specific concern regarding the convenience close function on certain 2025 Audi A5 and S5 models. This bulletin provides a solution for vehicles where the 'convenience close function via sensor on door handle sensor does not work'. Owners of affected vehicles may notice this feature is inactive, requiring a software update to restore its functionality.

This TSB outlines the necessary steps for dealerships to reactivate the convenience close feature, which was temporarily deactivated during a specific production period. The solution involves a software update to the Vehicle Electrical System Control Module.

Symptoms: Understanding the Convenience Close Function

Owners of affected 2025 Audi A5 and S5 vehicles will find that the convenience close function, typically activated by a sensor on the door handle, is non-operational. This means that when attempting to lock the vehicle by touching the door handle sensor, the system does not respond as expected to close windows or the sunroof, or to lock the doors without using the key fob.

The specific customer complaint noted in the TSB is: "The convenience close function via the sensor on the door handle does not work." This directly impacts the ease of securing the vehicle and its windows with a simple touch, a feature many Audi owners rely on for convenience and security.

Technical Background: A Planned Deactivation

According to TSB 2079931/1, the convenience close function was intentionally deactivated for vehicles manufactured after April 23, 2025. This was a temporary measure during production. The function is scheduled to be reactivated in production from approximately week 38 of 2025 onwards. This indicates that a specific window of 2025 model year vehicles will have this function deactivated from the factory.

While the TSB does not specify the exact reason for this deactivation, such actions are typically taken for software adjustments, regulatory compliance, or to address unforeseen operational considerations that arise during early production phases of new model years.

Repair Procedure: Software Update for Reactivation

To resolve the issue where the Audi A5 convenience close function is not working, a software update is required. Dealership technicians are instructed to first check for the visibility of TSB 2079690, titled "00 Combined software update 03.10.00/C (28.13.01) KD2". If applicable, the software update described in TSB 2079690 must be performed.

Following the software update, technicians must run a specific test program named "Technical Product Information 2079931". This program can be accessed within the diagnostic system under the path: 0009 - Vehicle Electrical System Control Module - J519 (HCP4) -> 0009 - Vehicle Electrical System Control Module, Technical Product Information -> Technical Product Information 2079931.

Performing a software update typically involves connecting a battery charger to maintain stable voltage during the process, as well as utilizing Audi's Guided Functions (GFF) diagnostic system to ensure correct installation and configuration. This update is designed to reactivate the convenience close functionality within the J519 (HCP4) Vehicle Electrical System Control Module.

Important Warranty Information

For vehicles still under warranty, this software update should be covered. The TSB specifies a Service Number of 5711 and a Damage Code of KD02 for warranty claims. The labor operations include "Software update, including connecting battery charger" (code 0151 0010, estimated at 130 Time Units) and "GFF / Guided Functions" (code 0150 0060, time stated on the diagnostic protocol).

Important Warning: The TSB explicitly states: "If the vehicle is outside of any warranty, this Technical Service Bulletin is informational only." This means that owners of vehicles no longer covered by warranty may be responsible for the cost of this software update. All warranty claims must adhere to the Audi Warranty Policies and Procedures Manual.

What Owners Should Know

If you own a 2025 Audi A5 or S5 and experience the 'convenience close function via sensor on door handle sensor does not work' issue, it is recommended to schedule an appointment with your authorized Audi dealer. Since this TSB is dated for release in November 2025, and addresses a function deactivated after April 23, 2025, for reactivation from week 38/2025, it's crucial to understand that this is a pre-emptive or future-dated service action.

Your dealer will be able to confirm if your vehicle falls within the affected production range and perform the necessary software update to restore the Audi A5 convenience close feature. Always ensure your vehicle's software is up to date to benefit from all intended features and improvements.
