2025 Audi A5/Q5 Head-Up Display Not Working TSB 2080567/1

Symptoms

Owners of affected vehicles may experience the head-up display intermittently not working. This means the windshield projection, which provides critical information, navigation, communication, and entertainment details, may cease to function without warning. This intermittent failure can be a significant inconvenience, impacting the driver's ability to quickly access information without diverting their gaze from the road.

Fault Codes / DTCs

When the head-up display intermittently stops working, technicians performing a diagnostic scan may find specific Diagnostic Trouble Codes (DTCs) stored in the vehicle's event memory. The primary DTC associated with this issue is:

Diagnostic Address	Diagnostic Trouble Code	Fault Symptom	Storage State
0082 - Head-Up-Display	B1BE8F0	Video transmission Log error	static

This DTC B1BE8F0 indicates a video transmission log error within the head-up display control unit (diagnostic address 0082). It is crucial to note that this TSB specifically applies when only DTC B1BE8F0 is logged. If another DTC, such as B125C01: Video cable electrical malfunction, is also present, a different diagnostic and repair procedure related to the video cable should be followed first using Guided Fault Finding. The presence of B125C01 indicates a hardware issue rather than a software one.

Diagnosis / Trigger Conditions

The diagnostic process for the 2025 Audi A5 head-up display not working begins with verifying the customer's complaint of an intermittently non-functional head-up display. Technicians should note that the complaint can only be reproduced intermittently. A diagnostic scan must then be performed to check for stored fault codes in the vehicle's event memory, specifically looking for DTC B1BE8F0 in the head-up display control unit (diagnostic address 0082). The key condition for this TSB to be applicable is that DTC B1BE8F0 must be logged without the simultaneous presence of DTC B125C01, which points to a physical video cable issue. If both are present, the video cable malfunction must be addressed first using Guided Fault Finding. If only B1BE8F0 is found, the issue is confirmed to be a software-related problem.

Technical Background

Audi has identified the root cause of the intermittent head-up display malfunction and the associated DTC B1BE8F0 as a software issue within the head-up display control unit (diagnostic address 0082). This indicates that the hardware itself is not faulty, but rather the programming or logic governing its operation requires an update. To prevent this issue in future vehicles, Audi plans a production change in the fourth quarter of 2025 to incorporate the updated software into newly manufactured models.

Repair Procedure Summary

The recommended repair for a 2025 Audi A5 head-up display not working, when only DTC B1BE8F0 is present, involves a software update to the head-up display control unit. This procedure is detailed in a separate Technical Service Bulletin, TSB 2079690, titled "00 Combined software update 03.10.00/C (28.13.01) KD2." The process typically involves connecting the vehicle to an Audi-approved diagnostic system, downloading the latest software version, and then flashing the head-up display control unit. It is critical to ensure a stable power supply throughout the software update process to prevent potential control unit damage or interruption. This combined software update is designed to resolve the internal software logic error that causes the intermittent display malfunction and the B1BE8F0 DTC.

Required Tools or Parts

No specific replacement parts are typically needed for this software-related issue. However, the repair procedure requires specialized diagnostic equipment, specifically an Audi-approved diagnostic system, to perform the software update. Crucially, a battery charger must be connected to the vehicle throughout the software update process to maintain a consistent voltage and prevent battery discharge. This ensures the programming is not interrupted, which could potentially damage the control unit. The software part numbers involved in the update for diagnostic address 0082 - Head-Up-Display are *.919.617.D* with software version 2340 and *.919.617.T* with software version 2427.

Warranty Information

For vehicles still under warranty, this software update is covered by Audi. The claim type for this repair is generally covered if the vehicle is within its warranty period. The service number associated with this repair is 9091, and the damage code is 0039. Labor operations for the software update, including connecting the battery charger, are coded as 0151 0010. A fixed rate for the software update, including all required preliminary and follow-up work such as bus sleep cycle and calibration drives, is covered under labor operation 0151 0040, allocated 130 TU (Time Units). In cases where additional attempts are needed after a flash abort, an additional lump sum of 50 TU can be claimed per documented attempt under labor operation 0150 9999. All warranty claims must be submitted in accordance with the Audi Warranty Policies and Procedures Manual. When performing the combined software update, time stamps are not required for billing under warranty, allowing technicians to work on other vehicles simultaneously or for non-productive personnel to perform the update.

Important Warnings

Owners should be aware that if their vehicle is no longer covered by warranty, this Technical Service Bulletin 2080567/1 is for informational purposes only. This means that while the bulletin identifies the problem and solution, the cost of the software update may not be covered by Audi. Always confirm your vehicle's warranty status with an authorized Audi dealer before proceeding with any repairs. Additionally, this TSB is strictly applicable only if the event memory entry B1BE8F0: Video transmission log error is logged without the simultaneous presence of DTC B125C01: Video cable electrical malfunction. If both fault codes are present, the technician must first address the video cable issue using Guided Fault Finding before applying the software update outlined in TSB 2079690.

Owner Action

If you own a 2025 Audi A5, Q5, S5, or SQ5 and are experiencing your head-up display intermittently not working, it is recommended to schedule an appointment with an authorized Audi service center. Inform the service advisor about the symptoms you are experiencing and mention Technical Service Bulletin 2080567/1 and DTC B1BE8F0. The service center will perform a diagnostic scan to confirm the presence of the fault code and determine if the software update is the appropriate solution for your vehicle. Ensure to inquire about warranty coverage for the repair.
