Prepare a decoder in advance, then use the decoder to read the fault code and record it. Take the retrieved fault code to a local repair shop for analysis and repair by relevant personnel.

I just fixed a similar issue. Common causes for display system problems include software conflicts, screen damage, or loose connection cables. The first step is to restart the MMI system: hold down the center console volume button for about 10 seconds until the screen goes black and then turns back on. If the issue persists, open the hood and check the fuse box—the fuse numbers are in the manual, and replace any blown fuses. The connection cables are under the dashboard; carefully remove and check for any looseness. If the problem continues, it might be a hardware failure requiring replacement or a software update—don’t delay, go to the 4S shop for inspection. The display system includes dashboard warning lights; if damaged, it can hide potential hazards and affect safe driving, so it’s best to address it early to avoid accidents.

My experience with cars displaying faults tells me that safety should be the top priority. Once the screen shows static or goes blank, immediately find a safe place to pull over and check it; try restarting by holding down the power button to reboot the system. If that doesn't work, don't push your luck—drive slowly to a service center or call for roadside assistance. Hidden dangers like engine warning failures may be present, so note down any error codes displayed on the screen for easier diagnosis. Make it a habit to avoid parking in high-temperature environments to prevent display aging. During regular maintenance, ask the technician to check the wiring and update the system to prevent frequent malfunctions.

When dealing with display issues, directly restart the MMI system: hold down the volume knob for a few seconds, which usually restores it. If that doesn't work, check if the software needs an update by connecting your phone to the system to check for push notifications. Screen glitches are often caused by software bugs, and resetting the settings can solve the problem, but be careful as you might lose data. Blown fuses are rare, but check the corresponding section in the fuse box. These steps are simple and easy to do, saving time and effort.

To prevent display malfunctions in my , I focus on daily maintenance: avoiding prolonged exposure to direct sunlight to prevent screen heat damage, and regularly updating system software via the Audi app. During routine maintenance, I make sure to check connection cables and fuses to prevent minor issues from accumulating. I refrain from using third-party apps that could interfere with the infotainment system, reducing the risk of bugs. These good habits have significantly lowered the malfunction rate.

When my displays a system malfunction that cannot be resolved, going to a professional shop is the best choice. If a restart doesn’t work, drive directly to the 4S dealership—they have diagnostic tools to check whether it’s a hardware failure or a software error. For example, screen panel replacement or module repair may not necessarily be expensive. Avoid attempting DIY fixes on complex components to prevent further issues, as safety is the top priority. Display problems may affect navigation and warning functions, so getting them fixed early ensures worry-free driving.
