Attach an Elsa printout showing the “open” status to the repair order. • If this UPDATE appears to have already been performed but the code still shows open in Elsa, contact Warranty before proceeding further. Another dealer may have recently performed this UPDATE but not yet entered a claim for it in the system. • Elsa may also show additional open action(s); if so, inform your customer - this work can be done while the vehicle is in for this UPDATE. • Contact the Warranty Helpline (U.S.) or the Warranty Campaign Specialist (Canada) if you have any questions. • Enter the VIN in Elsa and proceed to the “Campaign/Action” screen. TIP On the date of repair, print this screen and keep a copy with the repair order. • Confirm the Campaign/Action is open. If the status is closed, no further work is required. • Note the Applicable Criteria ID for use in determining the correct work to be done and corresponding parts associated. CRITICAL REPAIR STEP STOP! If multiple software update Campaign/Actions are open, they must be performed in order of the Start date . The oldest should be performed first. • All Safety Recalls must be completed prior to completing this campaign. • Proceed to Section A The repair information in this document is intended for use only by skilled technicians who have the proper tools, equipment and training to correctly and safely maintain your vehicle.

The battery charger is connected to the vehicle battery and remains connected for the duration of the software update. • Battery voltage must remain above 12.5 volts for the duration of the software update. Failure to do so may cause the update to fail, which could result in damage to the control module. Control modules damaged by insufficient voltage will not be covered. The screen saver and power saving settings are off. • Failure to do so may result in the tester entering power save mode during the software update, which could result in damage to the control module. The VAS Diagnostic Tester is plugged in using the supplied power adapters. • Under no circumstances should the tester be used on battery power alone during the software update. Failure to do so may result in the tester powering off during the update, which could result in damage to the control module. Flash process through “Audi Flashing” not Guided Fault Finding (GFF). • DO NOT USE Guided Fault Finding (GFF) to perform this flash. Using GFF will cause the flash to take longer. Requests for additional time will not be considered. The VAS Diagnostics Interface MUST ONLY be connected to the tester with a USB cable. • Performing a software update using a Bluetooth or WiFi connection increases the risk of losing connection during the update, which could result in damage to the control module. It also greatly increases the time required to perform the update. Requests for additional time or parts will be denied if the GFF log shows the update was performed using Bluetooth or WiFi. TIP As a best practice, customer presets should be documented prior to performing any update in the event these settings are lost during the update.
