The failure pattern owners describe
The 2020 Audi A4 Allroad MMI system has a widespread reboot problem that began in February or March 2025. The MMI screen goes black and stays unresponsive for about 60 seconds per reboot, sometimes occurring as frequently as every 2 to 5 minutes or up to 10 times in an hour. During each reboot, the backup camera, parking sensors, rear cross-traffic warning, navigation, hands-free calling, Android Auto, and Apple CarPlay all go offline. Drivers lose critical safety features especially during reverse parking and highway driving when reboots require PIN entry or repeated taps to get the system back online.
Owners began seeing this problem cluster around the same timeframe across many 2020 model-year vehicles, suggesting a software issue rather than individual hardware failures. Software updates applied by Audi dealers have not fixed the problem and have made it worse in some cases—one owner received two software updates and a $5,000 module replacement (negotiated to 90% discount) but continued to see even faster reboots afterward. Dealers quote $4,500–$5,000 for module replacements without any guarantee of success. Multiple Technical Service Bulletins reference software fixes, but owners report these do not work. One owner's backup camera failed mid-reverse after a software update, leaving the vehicle stuck for 30 seconds in a dangerous position. Another owner reports an SOS (emergency contact) system failure with no hands-free phone pairing available.
Failure modes owners describe
MMI spontaneous reboots
The MMI (multi-media interface) system reboots unexpectedly and repeatedly while driving, sometimes as frequently as every 2–5 minutes or as many as 10 times per hour. Each reboot causes the screen to go black for approximately 60 seconds, during which the system is completely unresponsive. Owners report the reboots began in February or March 2025, with a cluster of reports suggesting a widespread issue tied to specific software versions and production dates.
When: February–March 2025 onset; occurs at all speeds, on all road types, and at rest; independent of whether Bluetooth, USB, Apple CarPlay, or wireless charging are active
Symptoms owners cite: Black screen lasting ~60 seconds per reboot; Loss of backup camera and rear obstacle detection during reboots; Navigation system disabled until reboot completes; Hands-free phone tethering / cell phone connection lost; Android Auto and Apple CarPlay disconnected; Parking sensors and cross-traffic warning inoperative during reboots; SOS emergency contact button inoperable; Sluggish volume knob response and CarPlay navigation sluggishness reported by some owners; Requires PIN entry or repeated MMI screen taps to restore functionality post-reboot; Safety system communication errors logged when parking sensors detect obstacles during reboot
Repairs/costs cited: Software updates applied at dealerships (e.g., Flemington Audi, April 2025 service) have failed to resolve the issue and in some cases made reboots more frequent. One owner received two software updates and a 5F module replacement (quoted at $5,000, Audi offered 90% discount) but all three attempts resulted in faster rebooting. Dealers have quoted $4,500–$5,000 for module replacements without guarantee of resolution. One owner mentions TSB 2078437/1 as a claimed fix, for which Audi charged $400–$600. Dealers want diagnostic fees and have stated the only repair is full computer module replacement out of pocket.
Recalls/TSBs owners mention: TSB 2067021, TSB 2076404, TSB 2069112, and TSB 2078437/1 reference software updates intended to address infotainment issues. Software updates have been performed but have not resolved the issue and have sometimes worsened it. Audi canceled a prior recall around the 'conbox' system; that repair reportedly crippled the system and led to ongoing connection failures.
SOS system failure and emergency connectivity loss
The SOS (emergency contact) system fails, disabling the emergency contact button and preventing hands-free phone pairing and operation. One owner reports this failure occurred after a prior SOS module replacement performed 14 months earlier. The failure message received states: 'No data connection could be established. Please check the network coverage.' This renders the vehicle unsafe in emergency situations.
When: Reported in March 2023 for one complaint; failure occurred post-prior module replacement (14 months prior); timing relative to 2025 MMI reboots is unclear
Symptoms owners cite: Navigation unavailable; Emergency contact button inoperable; Cell phone no longer paired to the car; Vehicle does not recognize the cell phone; Hands-free phone operation impossible; Error message: 'No data connection could be established. Please check the network coverage.'
Repairs/costs cited: SOS module was replaced approximately 14 months prior to complaint. Module is currently installed in the vehicle and available for inspection.

Shortly after my warranty expired last september ([XXX]) my 2020 Audi A4 Allroad started to experience random episodes of the car's main entertainment touch screen rebooting in the middle of the car being operated. This usually would only happen once or twice during maybe an hour long car ride. Then this spring, starting in mid-March the car started to experience the MMI reboots more often, say…
The MMI (Information and entertainment system) 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…
Infotainment system began to randomly reboot after about 20min and then overtime every 2-3 minutes.
Audi mmi/infotainment reboots repeatedly while driving. It removes my attention from driving and is extremely distracting. Also fails when backing up and back up camera goes black. I have not taken to a dealer as this has been a frequent problem among other 2020 Audi owners.
Center console screen reboots at random intervals and as many as 10 times in 60 minutes. Complete reboot of the system renders backup camera and other surround view cameras inoperable.
Vehicle info system (MMI) unexpectedly and repeatedly reboots, affecting rear backup camera and parking assist radar functions at critical moments in addition to navigation and other vehicle functions. In addition to the safety issue with the rear camera and radar failing unexpectedly, the reboot creates distraction for the driver.
The MMI (the display with radio, carplay, cameras, warnings etc) restarts without any warning every 5-10 minutes. Does not seem to depend on if apple car play, bluetooth, backup camera etc is used at the time. In 2 cases this has happened while using the backup camera when going in reverse (and many more times when using for media play). This lead to the backup camera not showing and warnings…
I own a 2020 Audi and have been experiencing a persistent and widespread issue with the MMI (Multi Media Interface) system. While driving, the MMI randomly shuts down and reboots multiple times during a single trip. This happens whether or not I have any devices connected via Bluetooth, USB, or Apple CarPlay. The shutdowns are completely unpredictable and can occur at any time, causing the loss…
The MMI (multimedia interface) 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 process is extremely…
The MMI system and all associated functions resets without warning mid drive. The Audi dealership has a bulletin that says a software update is the solution, but has made the problem worse - rather than intermittent resets (once every few days) the system now resets multiple times on short drives (5 times within 20 minutes). This turns off all navigation, radio, phone, CarPlay, Bluetooth, and…
