2021-2022 Audi Models Second Key Fob Service Action 57i3

Why This Matters

Some 2021-2022 Audi models were initially delivered to customers with only one key fob instead of the standard two. This situation can be inconvenient for owners who expect to have a complete set of keys for their vehicle. The absence of a second key fob can also pose practical challenges, such as sharing the vehicle with another driver or having a spare in case of loss or damage to the primary key.

Audi has initiated Service Action 57i3 to correct this oversight. This action ensures that affected vehicle owners receive their missing second key fob, restoring the expected functionality and convenience that comes with owning a new Audi vehicle. The provision of this second key fob is performed at no cost to the owner.

What's Being Addressed

Audi Service Action 57i3 specifically addresses the provision of a second transmitter, or key fob, for certain 2021-2022 Audi models. This service action is a proactive measure by Audi to ensure customer satisfaction and rectify the initial delivery of vehicles with an incomplete set of keys. The process involves assembling and programming a new key fob for the vehicle.

This work is performed free of charge for eligible vehicles. The estimated time required to complete the service action is approximately one hour. Owners of affected vehicles will receive a complete, fully functional second key fob that is programmed to their vehicle's immobilizer system.

Repair Procedure Summary

The repair procedure for the Audi key fob service action 57i3 involves several steps to program the new key fob to the vehicle's immobilizer system. This process is designed to be performed by authorized Audi technicians using specialized diagnostic equipment.

1. Key Assembly: The new key fob is assembled using the customer's existing spare emergency bladed key. This ensures the physical key portion is correctly matched to the vehicle.
2. Vehicle Preparation: Technicians access the battery charging posts, switch the ignition on, apply the parking brake, and switch off all non-essential electrical consumers such as headlights, heated seats, and climate control to prevent battery drain during the programming process.
3. Diagnostic Connection: A Diagnostic Tester, such as the VAS6150X or VAS6160X, is connected to the vehicle. The ODIS program is then started to facilitate communication with the vehicle's control modules.
4. Power Supply: A Battery Tester/Charger, like the GRX3000VAS, is attached in power supply mode to the vehicle's battery charging posts. This maintains stable voltage throughout the programming sequence.
5. Diagnostic Scan: A Guided Fault Finding (GFF) Diagnostic scan is performed to identify any existing issues and ensure the vehicle is ready for programming.
6. Key Programming: The technician navigates to the Special Functions tab within the ODIS program and selects the test plan labeled "Immobilizer, servicing." This guides them through the process of programming the additional key.
7. On-Screen Prompts: The technician follows the on-screen prompts, entering the total number of keys to be matched to the vehicle. This step is crucial for correctly registering the new key with the immobilizer.
8. Finalization: After the new key is successfully programmed, the technician exits the GFF program and sends the diagnostic protocol online, completing the service action.
