2025 Audi Models Bluetooth/Smartphone Interface Connection Issues TSB

Owners of certain 2025 Audi models may experience issues with their vehicle's Bluetooth and Audi smartphone interface. These problems, which include slow connection times and interruptions, are detailed in Audi's Technical Service Bulletin (TSB) 2079418/1. This TSB serves as a Pending Service Solution (PSS), indicating that while the problem has been identified, the final software fix is still under development.

This communication, identified as TSB 2079418/1, is particularly relevant for owners experiencing 2025 Audi Bluetooth connection issues or problems with their smartphone integration. It provides guidance to dealerships on how to manage customer complaints while awaiting the official software update.

Symptoms of Bluetooth and Smartphone Interface Issues

Customers have reported specific symptoms related to their vehicle's connectivity. These include instances where the "Bluetooth and/or Audi smartphone interface sometimes take a long time to connect." This can lead to frustration when trying to use hands-free calling or navigation features. Additionally, some owners have observed that the "reception bar in the MMI is sometimes greyed out" during this time, suggesting a loss or degradation of the wireless signal crucial for these functions. These intermittent connectivity problems can significantly impact the user experience.

Dealership workshops have confirmed that these complaints can sometimes be reproduced during diagnostic checks, validating the customer experiences and indicating a verifiable technical fault.

Technical Details and Root Cause

Audi has determined that the root cause of these connectivity problems is a software issue within the vehicle's "0075 - Emergency call module and communication unit." This critical control unit, designated as DA 0075, is responsible for managing both emergency call functions and general communication within the vehicle. The issue specifically stems from the software running on this module, which currently includes versions such as 0723 and 0732.

For 2024 and 2025 model year vehicles, Audi is actively developing a comprehensive software package designed to address these and other related complaints. This upcoming update is part of a larger initiative referred to as the "Cluster 3B+ customer service package." This package aims to fix several issues in one repair. Further details on the distribution and deployment of this software package, including its impact on various control units like MIB3, ConBox, OCU3, AED2, and the gateway, are outlined in a separate document, TSB 2079416. This related bulletin provides an overview of customer service packages for MLB and MQB platforms after UNECE deployment, detailing how this software will be distributed.

Important Warnings for Owners

Audi has provided specific instructions for dealerships and, by extension, for owners regarding this pending issue. It is crucial for owners to understand these directives to avoid unnecessary service or costs:

• Do not replace any components for this condition since this will not resolve the customer's concern. This is a critical warning. Since the problem is purely software-based within the "0075 - Emergency call module and communication unit," replacing hardware components will not fix the underlying issue and could lead to unnecessary expenses or wasted time.
• A solution is expected to be available by the end of the 4th quarter of 2025, though this timeline is subject to change. Owners should be aware that a definitive fix for their 2025 Audi Bluetooth connection issues is not yet released, and patience is required.
• This TSB (2079418/1) is informational only and is not applicable to any Audi Warranty claims for the repair itself, as the repair is not yet available. Dealers are instructed to explain this to customers.

What to Do If You Experience These Issues

If you own a 2025 Audi model and are experiencing problems with your Bluetooth or Audi smartphone interface, it is recommended to visit your authorized Audi dealership. While a permanent fix is not yet available, the dealership will explain the situation and the expected timeline for the software solution. They will inform you that no repairs are necessary at this point, as the software update is still pending.

Technicians are instructed to create a Pending Service Solutions (PSS) record in the PSS application, accessible through the Pending Service Solutions (PSS) link in AccessAudi (under Related Links >> Service). This process helps Audi track the prevalence of the issue across its fleet and ensures that your vehicle is noted for the upcoming software update. By reporting your 2025 Audi Bluetooth connection issues, you contribute to the data that helps prioritize and roll out the final solution when it becomes available.
