2021-2022 Audi MMI Display Flickering or Distorted TSB

Symptoms

Owners of affected 2021-2022 Audi vehicles may notice several issues related to the lower MMI display (J685). These include:

• The lower MMI display (J685) flickers sporadically, or the display area looks distorted.
• HVAC settings change by themselves.
• Touch inputs are detected on the lower display without user interaction.

It's important to note that workshop findings indicate no relevant diagnostic trouble codes (DTCs) are stored in conjunction with these symptoms, meaning a check engine light or specific fault code may not appear.

Technical Background

Audi has identified that a software malfunction within the MIB3 system's lower MMI display is the root cause of the flickering, distortion, and unintended touch inputs. This software issue prevents the display from operating correctly, leading to the observed customer complaints.

Repair Procedure Summary

Audi Technical Service Bulletin 91 23 60 2068721/2 outlines a software update procedure to correct the lower MMI display malfunction. This TSB supersedes previous bulletin Group 91 number 22-53, dated December 1, 2022, and also replaces Pending Service Solution (PSS) TSB 2066224. The repair involves updating the MIB3 Display (J685) software.

The update process typically takes approximately 20-30 minutes, including 10-20 minutes for the software update itself and an additional 10 minutes for the Service Version Management (SVM) work. Technicians will utilize an ODIS Tester and follow specific instructions from related TSBs, including TSB 2060523: 91 MIB3 Software Update Instructions. The update requires the use of SVM code 636S003.

For situations requiring a manual update due to SVM code or server issues, Method 2 (update via the Red Engineering Menu, or REM) is specified for A6/A7 models, using SD Creator Part Number 4K1906961A.

Required Tools or Parts

To perform the software update, Audi service technicians will need specific equipment and parts:

• ODIS Tester: For diagnostic and programming functions.
• SVM code: A specific code, 636S003, is required for the software update.
• MIB3 Display (J685) Software update on USB Flash Drive: This can be sourced via a USB Flash Drive (part number 4K1906961A) or downloaded from MirrorServer using the SD Creator Program, as detailed in TSB 2047812: 00 SD Creator.
