2020 Audi S4: screen or infotainment failure

Filed Oct 21, 2026 · Electrical · MN

My instrument cluster and its replacements have malfunctioned multiple times. The original instrument cluster/virtual cockpit failed to boot and had a black/blank screen on 4/19/2024 at 29,687 miles and was replaced on 5/15/2024 at 29,923 mi (11/13/23 production). That replacement one worked fine for a while and then did the same thing on 7/15/2024 at 33,655 miles and on 1/10/2025 at 42,532 miles. The instrument cluster was then replaced again on 2/10/2025 at 43,841 miles (production date 9/18/23). That replacement unit took only a couple of days to act up again with the blank screen on startup on 2/13/2025 at 43,965 miles and once more on 8/1/2025 at 52,673 miles. 3rd replacement 9/9/25 (production date 9/18/23) and has had the same issue on 4/18/2026 at 66,528 miles and once again on 9/30/2026 75,069. The 3rd replacement failed before the 12 month, 12,000 miles warranty but then was out of warranty by the time anything could be done.

I'm currently waiting to hear back from the dealer to get the instrument cluster replaced once again.

The main infotainment system is stuck restarting every 1-2 minutes. When the car is put into reverse, the rear back up camera will turn off while the vehicle is in motion and not resume.

The MMI (multimedia interface) screen goes dead and reboots frequently (every 2-5 minutes) while driving. It is extremely frustrating and distracting. In addition, when the screen blacks out while driving in reverse, the backup camera, back up sensors and cross traffic warning systems do not operate until the system reboots, which can take several minutes. This problem occurs constantly while driving and requires me to re-enter navigation destination while driving. Using CarPlay for navigation is also affected, as the system reboots whether or not I am using a secondary media source like CarPlay, and I have to re-enter the destination whenever the MMI reboots. Also the MMI needs me to re-enter user information on the screen with every failure in order to get the system running again, which is very distracting while driving. I am not even able to turn off the screen to avoid the distraction, as it will automatically fail and reboot while turned off. This will turn the screen back on in the start-up mode and cause the radio to turn on randomly. When this happens, the stereo volume will sometimes come back on, and other times it appears to be playing music and radio stations, but the volume control will not work. Then it will randomly come back on very loud. The distractions are unavoidable, as I would be happy to just leave the MMI system off, but it is not possible! Please require Audi to fix this problem!!! The dealer/manufacturer does not seem to be interested in fixing the issue, as is evidenced by the many complaints I have found on the federal safety agency website.

The Multimedia Interface (MMI) Touchscreen Radio will constantly reboot while driving regardless of variables. Diagnosis’ have proven problem to be undeterminable, this is a serious safety concern as I have lost back up camera and other safety features while driving, while I await the system to reboot. This reboot has been occurring non-stop since January. My research online and in other forums has led to a substantial group of vehicle owners suffering from the same issues across their vehicles. Audi has made no effort to rectify with the dealership simply stating they can charge to diagnose or replace. If it was an isolated incident I would be understanding as Maintenance problems will arise, but to have a substantial population discussing this issue ad nauseum seems to be more widespread with no solutions.

The MMI spontaneously reboots numerous times while driving. When the reboots happen, the screen goes black, and key systems such as the backup camera, rear obstacle detection, and navigation become unavailable until the reboot completes and the systems reload. Restoring functionality requires user input to get through the loading screens. The issue started in February 2025. I have attempted a factory reset (which did not solve the issue), and I have performed an OBD scan, which returned no fault codes. This appears to be a widespread issue based on the numerous reports found on user forums online, affecting the same model year vehicles (for multiple examples, refer to [XXX] ). It is also interesting that most of the users experiencing this issue also report it starting around the same time (Jan/Feb 2025), and they all have similar software versions, and likely production dates. This should be considered a safety issue, as the reboots can happen in the middle of a reverse parking maneuver, and they render the backup camera and obstacle detection sensors completely inoperative until the system reloads. They also impact safety on the highway, as the reboots completely disable the navigation screens and require multiple user inputs to restore, while driving.
