2021 Audi MMI Display Turns Blue TSB 91 21 09 2063702/1

Symptoms: MMI Display Turns Blue

Owners of certain 2021 Audi models, including the 2021 Audi Q8, may experience an issue where the Multi Media Interface (MMI) display turns completely blue. This can affect both single and dual-screen vehicle configurations, rendering the infotainment system unusable. The symptom is specifically described as "The MMI display turns completely blue."

Technical Background

According to Audi's Technical Service Bulletin PSS 91 (91 21 09 2063702/1), the root cause of the MMI display turning blue is an issue within the display driver. This internal software or hardware malfunction prevents the MMI system from rendering images correctly, leading to the solid blue screen.

Important Warnings for Owners

Audi explicitly states: "Do not replace any components for this condition since this will not resolve the customer's concern." This means that replacing the MMI unit or related hardware will not fix the blue screen problem, as the issue lies with the display driver, which is expected to be resolved through a software update.

Workaround for a Blue MMI Screen

If your 2021 Audi Q8 MMI display turns blue, a temporary workaround is available. You can reset the MMI system by pressing and holding the On/Off/Volume button for 10 seconds or more. This action should cause the MMI to reboot, and it is expected to function normally afterward. This temporary fix can help restore functionality until a permanent solution is implemented.

Production Solution and Future Fix

Audi has indicated that a permanent solution for the MMI display turning blue is forthcoming. For vehicles produced in Model Year 2022 (MY22), updated software has been implemented to address this issue at the factory. For affected 2021 models, a permanent software update is anticipated to be available in the first quarter of 2022.

Next Steps for Owners

If you are experiencing the 2021 Audi Q8 MMI display turns blue issue, you should perform the MMI reset workaround as needed. While a permanent fix is expected via a software update, it's advisable to contact your authorized Audi dealer for the latest information regarding the availability of this update. Dealers are instructed to create a PSS (Pending Service Solutions) record for this condition through the AccessAudi portal or Elsa system.
