2022-2026 Audi MIB3 Navigation Database Reinstallation TSB

Symptoms of Audi MIB3 Navigation Database Issues

Owners of 2022-2026 Audi vehicles equipped with the MIB3 system may encounter various problems related to the navigation database. These issues are typically software-related and can manifest in several ways.

Common symptoms include:

• The navigation system, trip recorder, or navigation unit displaying an "error message" related to control modules or services.
• The navigation mode showing "no function" when attempting to select it.
• General navigation functionality problems, indicating a failure in the system.

Technical Background

Audi has identified that these navigation system issues stem from a software problem within the MIB3 MMI system. This Technical Service Bulletin (TSB) outlines a procedure for technicians to delete and reinstall the navigation database, which is expected to resolve the underlying software fault.

Important Warnings for Owners and Technicians

Several critical warnings are provided in this TSB to ensure proper procedure and prevent potential issues:

• Deletion of Navigation Database: Technicians should only delete the navigation database if explicitly specified in a TSB or if instructed by the Technical Assistance Center (TAC).
• Warranty and Recalls: If this TSB procedure is performed in conjunction with recall 91DZ, the standard warranty instructions for this TSB do not apply, as reimbursement will be handled under the recall's scope. If the vehicle is outside of warranty, this TSB is for informational purposes only.
• Software Download Browser: When downloading the necessary files for the update, technicians must not use Internet Explorer. Recommended browsers include Edge, Firefox, Chrome, or Safari.
• USB Flash Drive Management: The USB-C flash drive containing the navigation data should be retained as a workshop tool. It is not necessary to contact TAC or re-download the data if the drive is already prepared. Future updated navigation databases (NavDB) will automatically install via online updates after the initial NavDB is installed. It is also not required to keep the vehicle in a service bay or supervise the update once it has begun.
