2021-2022 Audi Models Bluetooth Connection Fault U110300

Owners of various 2021-2022 Audi models may experience difficulties establishing a Bluetooth connection with their phones. This problem is frequently accompanied by a specific diagnostic trouble code and a message displayed on the MMI system.

This technical service bulletin (TSB) 2064818/2, issued on March 3, 2022, provides instructions for diagnosing and resolving this Bluetooth connectivity issue. It supersedes a previous bulletin, 21-41, dated October 13, 2021, incorporating updates for additional model years.

Symptoms

Owners typically report that "It is not possible to establish a Bluetooth connection between a phone and the vehicle." When attempting to connect, the Audi MMI display may show the message: "The selected system is currently not available." This prevents the use of Bluetooth features for calls, media streaming, and other functions.

Fault Codes / DTCs

When diagnosing this issue, technicians will likely find the following Diagnostic Trouble Code (DTC) stored in the telematics control module, identified as J949 (address word 0075):

• DTC U110300: Production mode active

This specific code indicates that the telematics control module might be stuck in a production or transport mode, which inhibits normal Bluetooth functionality. Addressing this Audi Bluetooth U110300 fault is key to restoring connectivity.

Diagnosis

Workshop findings confirm that the DTC U110300 is stored in the telematics control module, J949. This module is responsible for managing the vehicle's telematics and communication features, including Bluetooth. The presence of this code directly correlates with the reported Bluetooth connection problems.

Repair Procedure Summary

To resolve the Audi Bluetooth U110300 issue, technicians are instructed to perform a specific diagnostic routine. The key step involves executing the control module replacement test plan for the telematics control module (J949) using ODIS Guided Functions. It is crucial to note that this procedure is performed without actually replacing the control module itself. The test plan is designed to reset or reconfigure the module, effectively taking it out of the 'Production mode active' state indicated by the DTC.
