Audi A4 backup camera problems

Filed Jul 1, 2026 · Driver assistance, Electrical · CA

The rear-view camera intermittently fails to engage when the vehicle is shifted into reverse. When the camera does display, the image sometimes shows horizontal glitch lines/artifacts. This affects backing visibility and parking safety and creates a risk of collision with pedestrians, objects, vehicles, or property. The concern was reported to Audi service along with other electrical/driver-assistance symptoms, suggesting a possible camera, wiring, module, signal-processing, or broader electrical fault. No crash, fire, injury, or fatality occurred. This complaint is being submitted because the rear camera/reverse display is a backing-safety system and the intermittent failure is unpredictable. The vehicle/component is available for inspection, and photo/video evidence and service communications are available.

This problem is extremely sporadic, and often remedies itself after car shut down, and sometimes require that the car sit for a period of time. I estimate the following issue happens ~1 time a month, or estimated 5% of the time. Weather (temperature specifically) does not appear to impact occurance. When reversing, at times the back up camera does not function properly. During these times, the parking sensors appear to work, but it's unclear if the emergency reverse automatic braking system is working. The backup camera issues present themselves in several different ways and are described below. 1) Scrolling view (think of an old time movie, where the image "scrolling" through the screen 2) Black, but not completely black, includes what appears to be interference (sometimes white pixels flash randomly throughout the screen) 3) Off color (almost like a color inversion), darks appear light, light colors appear dark, similar to how things when developing film in a dark room 4) Similar to #1 but instead it freezes, halfway through a scroll. Often times the picture is split, with the bottom on the top, and the top on the bottom, and a clear black line in the middle Opening and closing the trunk, tapping the camera, turning the parking sensor (and camera) off and on do not solve the issue when it happens. Neither does changing from R to P on the transmission lever. Issue always requires a restart, rarely does an immediate restart fix the issue. The tracking lines are also distorted when this happens. When not malfunctioning, camera system works perfectly. Recently, I came across the federal safety agency ID: 25V900000 which almost exactly describes my issues but my car is not included. I did recently ask the Dealer to look into it during my 40,000 mile service. They stated that no codes were in the system and they could further troubleshoot but the intermittent nature would likely result in no findings unless the issue is present on site.

My screen turns on and off consistently not allowing me to use my backup camera. Causing a small collision while backing up when the camera turned off unexpectedly. Additionally when it’s off it will auto break when I’m not close enough to hitting and it’s loud and yanked me. This has been an issue for some time and I’m seeing a significant amount of my models have this issue and it’s not safe.

My car's MMI keeps restarting while driving which affects the rear view camera and while backing up it can restart and go completely blank. I feel this puts my safety at risk while backing up. It also shuts down my bluetooth to my phone which can be a hazard while driving. I have called the dealership but they will not do anything without a large diagnosis fee which i cannot afford. They have said there are no recalls against it. No warnings prior to the failure and the failure happens every time I drive it, including multiple times per use.

Audi MMI system randomly goes dark and reboots during driving - this turns off the rear camera and any GPS system being used to navigate along with the sound system, etc.

My 2020 Audi A4 infotainment MMI keeps rebooting and takes over a minute or so to load back. This has been happening recently and i have rebooted the system and followed the Audi/reddit forums to seek any help but no resolution. It seems most of the 2020 Audis are facing similar issues. This issue is concerning and needs immediate attention since I have had instances where i lost backup camera while backing. Losing Navigation Capabilities or backup camera feature while backing up or driving has jeopardized me couple of times since i had to fumble and hit brakes as i was almost handicap momentarily. Audi is aware of this issue and have had issued TSB in 2020 which is attached here, but no recall was ever conducted which they should as this now an industry wide problem. Also, i got to know that S they have issued a 2021 MMI recall affecting over 44k Cars but not 2020, which is very surprising. Based on forums and other users it seems the Firmware version 3243 need an overhaul or even MMI module replacement if firmware update doesn't fix the issue. Request the authority to investigate this known issue for 2020 car line with similar intensity as this a widespread safety hazard. MMIs usually incorporate other modules as well so there is risk for ADAS failures or parking aids.

The MMI system, which is the display in the car, keeps rebooting every few minutes. It is extremely distracting while driving. Also during parking or back up the parking assistance and backup camera would suddenly disappear because the system reboots. The rear cross traffic warning stops working during reboot as well.

MMI (infotainment), and the dashboard screen will turn off randomly and reboot every 2 minutes. This is incredibly dangerous as it turns all sound off, and driving visuals like directions, and freezes or reboots, not where you last had it but from a different check point. It has happened while I have been backing up and backup camera has rebooted during backup. Parking Collision has also malfunctioned multiple times - but primary issue is the MMI rebooting even while driving on the freeway.

MMI Constant Rebooting - Follow up My 2020 Audi A4 Quattro's MMI system constantly reboots (~60 seconds), causing the screen to go black/blank. Component Failed: MIB3 infotainment software. This persistent issue leads to reboots and loss of digital display. System available for inspection. Safety Risk: Significant, recurring hazard. Critical safety features are inoperative for ~1 min during reboots, including: Rearview camera (backing/parking safety) Navigation Communication No manual bypass exists; driver loses vital visual information Problem Confirmation: Consistently reproducible. Dealer proposed costly hardware replacement with no guarantee, contradicting manufacturer guidelines for known software issues. Symptoms: continuous black screen, Audi splash, then re-initialization. Problem worsened over weeks. Manufacturer's Knowledge: Extensive owner research (AudiWorld, Reddit) confirms this as a widespread, documented MIB3 software defect for 2020 Audi A4/A5 models. Audi's own Technical Service Bulletins (TSBs) address this: TSB 2069112 (MIB3 improvements) TSB 2067021 (MIB3 malfunctions) These TSBs outline a specific, sequential software update process (e.g., older versions need TSB 2067021 first for TSB 2069112). Other owners successfully resolved rebooting with these updates. This malfunction is analogous to other Audi MIB3 software instabilities, as evidenced by the federal safety agency Recall Number 22V742 (Audi Campaign Code 91DZ). This recall for 2021-2022 Audi models addresses similar digital display/infotainment failures (e.g., rearview camera loss) via a no-cost software update. This demonstrates Audi's awareness of systemic MIB3 software issues impairing safety. I urge the federal safety agency to investigate this widespread 2020 Audi A4 issue and compel Audi to issue a recall for a no-cost software update (per TSBs) to all affected owners. More detailed documentation, including dealer records and owner videos, is available upon request as there is limited space to detail here.
