Important Warnings and Owner Advisories

Several critical notices are highlighted within TSB 2079690/7 that owners and technicians must be aware of:

• Prerequisite Campaigns: All open field campaigns must be performed in advance, following their publication date, before proceeding with this software update.
• Physical Key Requirement: A physical key (remote control key) is mandatory for performing the software update. The digital key and digital key card cannot be used for this procedure.
• Digital Key Reset (PR 2F1): For vehicles equipped with PR number 2F1, the digital key must be reset after the update to enable sharing with other users. If a digital key is already in use, resetting the key user will remove it, requiring re-setup.
• Mobile Data Deactivation: Owners should be informed that mobile data is automatically turned off after the software update and may need to be reactivated manually.
• Settings Readjustment: Various vehicle settings will need to be re-adjusted after the software update. A customer letter is attached to the TSB for this purpose, which dealers should provide to the customer upon vehicle return.
• High-Voltage Vehicles: For vehicles with high-voltage components (e.g., e-tron models), the high-voltage charging cable must be unplugged BEFORE the SVM code is entered to prevent battery charging during the update. Charging during the update can damage high-voltage components.
• SVM Configuration Tests: Under no circumstances should SVM configuration tests be performed if the software update via SVM was not fully completed and documented. Doing so may incorrectly identify already updated control units as faulty. The vehicle must be fully updated before documentation.
• Aborted Updates: If an update is aborted and a control unit needs replacement, technicians should not perform a configuration test. Instead, they should use the
