2021-2022 Audi MMI Display Turns Blue TSB

Symptoms

Owners of affected 2021-2022 Audi vehicles may experience a condition where the MMI display turns completely blue. This issue can affect both single and dual-screen MMI systems, rendering the display unusable. The symptom is clearly visible as the entire screen area changes to a solid blue color.

Technical Background

Audi has identified that the primary cause for the MMI display turns blue condition is an issue within the display driver software. This software malfunction prevents the MMI system from rendering graphics correctly, leading to the blue screen appearance.

Important Warnings for Owners

Audi explicitly advises against replacing any components, such as the MMI unit itself, to address this condition. Replacing parts will not resolve the underlying issue and is not a recommended repair. A permanent solution is currently under development by Audi.

Temporary Workaround

While a permanent fix for the Audi MMI display turns blue issue is being developed, a temporary workaround is available:

1. Reset the MMI: Locate the On/Off/Volume button for your MMI system.
2. Press and Hold: Push and hold this button for 10 seconds or more.
3. Reboot: The MMI system will then reboot and should return to normal operation.

This reset procedure can temporarily restore functionality to the MMI display.

What Owners Should Know

Audi anticipates a permanent software solution for the MMI display turns blue problem to be available in the first quarter of 2023, though this timeline is subject to change. Owners should be aware that no repairs are necessary at this point, and replacing components will not fix the issue. This Technical Service Bulletin (TSB) is informational and does not fall under Audi's standard warranty coverage for repairs.

Dealer Actions

For technicians, when a customer reports the MMI display turns blue, a Pending Service Solutions (PSS) record should be created in the PSS application. This can be accessed through the 'Pending Service Solutions (PSS)' link in AccessAudi (under Related Links >> Service) or via the Technical Assistance page in Elsa. This helps Audi track the prevalence of the issue while awaiting a permanent solution.
