2021-2022 Audi Bluetooth Not Available DTC U110300

Symptoms

Owners of certain 2021-2022 Audi models equipped with ConBox High may experience difficulty establishing a Bluetooth connection between their phone and the vehicle. This issue is often accompanied by a specific message displayed on the MMI (Multi Media Interface) screen.

The primary symptom is the inability to connect a Bluetooth device. When attempting to use Bluetooth, the MMI display will show the message: "The selected system is currently not available." This indicates a problem with the system's readiness to provide Bluetooth services, making hands-free calling or audio streaming impossible.

If you are experiencing this Audi e-tron Bluetooth U110300 issue, it's important to have your vehicle diagnosed by an authorized Audi service center.

Fault Codes / DTCs

When diagnosing the Bluetooth connection problem, technicians may find a specific Diagnostic Trouble Code (DTC) stored in the telematics control module (J949). This DTC helps pinpoint the nature of the fault.

Code	Description	Module
U110300	Production mode active	Telematics control module, J949 (address word 0075)

This U110300 code signifies that the telematics control module is in a 'Production mode active' state. This mode is typically used during manufacturing or testing and can interfere with normal Bluetooth operation, preventing the system from becoming available to the user.

Diagnosis / Trigger Conditions

The presence of DTC U110300 in the telematics control module (J949) is the key diagnostic indicator for this issue. This code suggests that the module is operating in a mode intended for manufacturing or testing, rather than normal vehicle use, directly impacting Bluetooth functionality.

The problem manifests as a direct failure of Bluetooth connectivity, where the vehicle cannot establish a connection with a phone. The MMI message "The selected system is currently not available." confirms the system's inability to function as expected. This condition directly relates to the Audi e-tron Bluetooth U110300 fault.

Repair Procedure Summary

To resolve the Bluetooth connectivity issue and clear the DTC U110300, Audi recommends a specific service procedure. Technicians should utilize the ODIS Guided Functions diagnostic system to address the telematics control module, J949.

The repair involves performing a dedicated "control module replacement test plan" for the telematics control module (J949, address word 0075) via ODIS Guided Functions. Crucially, this procedure is designed to correct the module's state without requiring the physical replacement of the control module itself. This indicates a software-based correction or configuration adjustment is the intended fix.
