2025 Audi A5 Connect Services Not Working TSB 2077111/2

Owners of certain 2025 Audi A5, S5, Q5, and SQ5 vehicles may encounter problems with their Audi connect services. This issue, addressed by Audi Technical Service Bulletin (TSB) 2077111/2, stems from a software malfunction affecting the vehicle's communication systems. The TSB, initially published on March 4, 2025, and revised on August 2, 2025, provides a detailed procedure for diagnosing and resolving these connectivity issues.

Symptoms of Malfunctioning Connect Services

If your 2025 Audi A5, S5, Q5, or SQ5 is experiencing issues with its connect services, you might notice several specific symptoms. The primary complaint is that the vehicle's online services are not functioning as expected. This can manifest in various ways, including:

• "Online weather information cannot be called up"
• "Online news cannot be called up"
• "Online traffic information is not available"
• "Satellite maps are not available"
• "Online radio is not available"

Additionally, the MMI display may occasionally show the message "Offline". Attempting to create a user in the MMI might fail, displaying messages such as "try again later" or "technical error occurred". These symptoms collectively point to the underlying software issue affecting the Audi A5 connect services.

Diagnosis and Trigger Conditions

Audi's TSB 2077111/2 indicates that the root cause of these connect service malfunctions is a software issue within the emergency call module control unit and communication unit, identified as J949. Technicians are instructed to first reproduce the customer's complaint to confirm the issue aligns with the TSB's description. This ensures that the prescribed repair will effectively address the problem.

Important Warnings for Owners and Technicians

It is critical for technicians to accurately diagnose the problem and ensure all criteria (model, chassis number, engine/motor, gearbox code, PR number, part number, software version, etc.) precisely match the TSB's requirements. Audi explicitly states, "Otherwise, this solution will not eliminate the problem and repeat repairs may be necessary. In such a case, the warranty claim may be rejected, and the cost of the parts may be charged back." Owners should be aware that attempting repairs outside of these guidelines could lead to unexpected costs.

Repair Procedure Summary

The repair for the malfunctioning Audi A5 connect services involves a multi-step process designed to reset and restore the communication unit's functionality. The procedure is divided into three parts:

Part 1: Control Module Restart

1. Step 1: Technicians must perform the ODIS routine designated as "Control module restart" for the emergency call module control unit and communication unit J949, which has a diagnostic address of 0075. After this step, the connect services are assessed to see if they are working.

Part 2: Fuse Manipulation (Model-Specific)

If the services are not restored after Part 1, a model-specific fuse manipulation is required:

• For Audi Q6 e-tron and Audi A6 e-tron:

  1. Switch off the ignition.
  2. Remove fuse 9 on fuse carrier C (SC9) for the J949 unit, located in the right footwell, for at least one minute.
  3. Reinsert the fuse into its position.

• For Audi A5 (FU) and Audi Q5 (GU) (which includes the 2025 Audi A5, S5, Q5, and SQ5 models):

  1. Switch off the ignition.
  2. Remove fuse SF1 on fuse holder B (2) for the J949 unit, located in the left footwell, for at least one minute.
  3. Reinsert the fuse into its position.

Part 3: Verification

After completing the previous steps, technicians must check that the emergency call LED is green, indicating proper functionality of the system.
