2021-2022 Audi MMI Display Turns Blue TSB

Symptoms

Owners of affected 2021-2022 Audi vehicles may observe that the Audi MMI display turns blue. The primary symptom is that "The MMI display turns completely blue," as shown in the bulletin's figures for both dual-screen and single-screen MMI systems. This condition indicates a malfunction in the display system.

Technical Background

This issue stems from a problem within the display driver software. The bulletin identifies that an error in this driver can cause the MMI display to turn blue, rendering it inoperable for the user.

Production Solution

Audi has implemented an updated software solution for this display driver issue in vehicles produced for the Model Year 2022 (MY22). This means newer vehicles may already have the fix integrated during manufacturing.

Repair Procedure Summary

For vehicles already on the road experiencing the Audi MMI display turns blue issue, the TSB outlines a temporary workaround and a long-term solution:

1. Workaround: To temporarily resolve the blue screen, reset the MMI system. This is done by pushing the On/Off/Volume button for 10 seconds or more. The MMI system will then reboot and should function normally afterward.
2. Permanent Solution: Audi is working on a permanent software solution, which is expected to be available in the first quarter of 2023. This update will address the root cause of the display driver problem.
3. Documentation: Dealerships are instructed to create a PSS (Pending Service Solutions) record in the PSS application via the AccessAudi portal. This helps Audi track the issue and affected vehicles.

Important Warnings

Owners and technicians should be aware of a critical instruction from Audi regarding this issue:

• "Do not replace any components for this condition since this will not resolve the customer's concern."

This means that replacing hardware components like the MMI display will not fix the underlying software problem and should be avoided. The issue is software-related, and a software update is the intended permanent remedy.

Owner Action

If your 2021-2022 Audi MMI display turns blue, you can perform the temporary MMI reset as described above. You should also contact your authorized Audi dealer. While a permanent fix is pending, the dealer can document your concern and advise you on the availability of the upcoming software update.
