2020-2021 Audi MIB3 Favorites, Destinations Deleted TSB

Symptoms Owners May Notice

Owners of affected 2020-2021 Audi A4, A4 allroad, S4, A5, A5 Cabriolet, A5 Sportback, S5, S5 Cabriolet, S5 Sportback, RS 5, and RS 5 Sportback vehicles may experience a frustrating issue with their MIB3 infotainment system. The primary symptom is that the system will sporadically delete crucial navigation data. Specifically, owners will find that their "last destinations, favorites and the home address are deleted sporadically." This means that personalized settings and frequently used locations are no longer available. The problem typically manifests after the system is restarted, where "all the destinations given above are no longer stored." This loss of data can occur without warning, requiring owners to re-enter their preferred locations.

Technical Background

Technical Service Bulletin (TSB) 2079619/1 identifies the root cause of the MIB3 system losing stored navigation data as a software issue. This problem affects vehicles produced before Week 25/21, which were equipped with an older version of the cluster 35 software. The complaint is described as occurring irregularly, making it potentially difficult for technicians to reproduce in a workshop setting. The core problem is that the system fails to retain saved destination data, including favorites and home addresses, after a restart. This specific software flaw prevents the MIB3 system from properly preserving user-defined navigation information.

Important Warnings

NOTICE If 91MM or 91DZ campaigns are still open on the vehicle, complete the campaign programming first before continuing. After the campaign is performed, proceed below.

This TSB includes a critical notice for service technicians. It means that if your vehicle has any other outstanding software update campaigns identified by codes 91MM or 91DZ, those must be completed by an authorized Audi dealer prior to addressing the MIB3 favorites deleted issue. Adhering to this sequence is essential to ensure proper system functionality and prevent potential conflicts or the need for re-work.
