You can take action to fix your Audi MultiMedia Interface (MMI) system’s problems with this article, which will explain the main reason(s) for its failure.
Here we go! Without further ado, let’s begin!
Audi MMI Screen Malfunctions: Causes and Solutions
There may be several reasons why your Audi MMI display is not functioning properly, such as the following:
Low Battery Voltage
A low battery or insufficient voltage reaching the Audi MMI screen is the most common cause of an unresponsive or blank Audi MMI screen. A steady supply of battery power is essential for the proper operation of the MMI system.
There may be voltage drops that cause the MMI screen to turn off, freeze, or not respond if the battery is old and can’t hold a charge.
If the battery is low, the screen may not be able to generate the 12+ volts that it needs to function. Likewise, loose wire connections and corrosion at battery terminals can reduce power output.
Battery discharge can result in the screen malfunctioning or turning off completely over time as the voltage drops below the required threshold.
MMI screen problems caused by insufficient voltage can often be resolved by testing or replacing the battery on an Audi that is more than 3-4 years old.
Maintaining stable voltage for the sensitive screen components will also be helped by checking for loose wiring or corroded terminals.
In order to keep your MMI screen powered on and working properly, you must maintain and charge your battery regularly.
Overheating
The MMI system in Audi offers many innovative features, but it has the limitation that, regardless of how hot or how cold it may be, the system is very sensitive to temperature changes.
A hot screen on your MMI could be causing it to stop working.
It was in 2011 that many Audi models suffered from overheating-related problems with the MMI interface.
In order for the MMI system to function properly, it had to be updated. The Audi MMI screen might not be working because of overheating.
You can check the screen’s function after reducing the interior cabin temperature if it is too high.
A Blown Fuse
Audi MMI screens that aren’t working may also be caused by blown fuses.
A blown fuse will also disable the MMI display since the screens are connected to the entire MMI system. The fuse box in the passenger compartment needs to be checked in order to rule this out.
The fuse that powers your car’s display can be found in your owner’s manual, then found in the fuse box. Make sure it doesn’t have any defects by taking it out of the slot.
A small metal bar should connect two pins if everything is okay. The old one may need to be replaced if it is darkened or missing.
If you install the wrong fuse, you could even start a fire. However, you want to get exactly the same fuse.
MMI software has a glitch
If the MMI system is malfunctioning or crashes, the software may be to blame.
In addition to using outdated software or running too many programs at the same time, there are a number of possible causes of this problem. In some cases, overloaded systems fail to function properly, including the touch screen.
After giving the screen some time, the system may need some time to resolve the problem if it still isn’t working properly. A hard reset of the MMI module is also possible.
The MMI Unit Failed
Audi MMI Screen Not Working can also be caused by a failure of the entire MMI unit.
If even one fiber optic cable fails, the entire system will fail, even though these cables transmit data rapidly and work extraordinarily well.
The MMI unit may need to be replaced if one cable fails, so it may not be possible to identify which one failed. Audi service providers can also help you determine if the unit needs to be replaced and which cable is broken.
Water Damage
In addition to water damage to the MMI module or amplifier, it is also possible for the Audi MMI screen to not work as a result of poor design.
A leaky rear window washer pipe can cause water damage to the amplifier in the trunk. A high level of moisture in the cabin may also be responsible for the problem.
It may be necessary to replace the module or amplifier if water damage is the cause of the problem and then reprogram it. It may be necessary for you to seek professional assistance in this matter.
Failure of the screen hardware
It is possible that the screen hardware had failed or there was physical damage.
There may be a physical breakdown of various MMI components as the system ages, including the graphics card, display driver, and monitor.
Be sure there is no damage to the screen. Make sure that other components of the system have been checked by a professional Audi service provider.
Calibration errors on touch screens
There is also a possibility that touchscreen calibration error is the reason for an unresponsive screen. You may experience problems with the screen if the touch input wasn’t aligned properly with the display.
Touch commands may not work properly or respond incorrectly.
The screen calibration needs to be checked at your local Audi service center.
Other devices causing interference
Has the MMI system been modified recently with aftermarket accessories? There is a possibility that the MMI system is being interfered with electromagnetically if this is the case. In addition to electronic devices, wireless transmitters can also interfere with radio signals.

Audi MMI Screen Not Working? Here’s how to fix it
There’s a common reason the Audi MMI screen doesn’t work, and this is one of them. Now that this problem has been identified, how can it be resolved? Several solutions can be found here:
- You will need to perform a hard reset. In some cases, you may need to contact an Audi service center. Search your owner’s manual or contact the Audi dealer for more information.
- Make sure your battery is in good condition and that it has been replaced if necessary.
- Fuse should be replaced if it has blown. You don’t want to end up with even worse issues, so make sure you get the right fuse.
- MMI needs to be replaced. If you suspect the whole system is gone, or if major components are damaged, this is the best option.
- Replace the screen. Replacing the screen might be a better idea if you notice physical damage.
- Replacing the amplifier if it’s damaged is a good idea.
Updating the software is necessary, lowering cabin temperatures if they’re excessive, and checking MMI unit connections is necessary.
However, whenever you feel that your MMI system has a defect, you should always take it to a manufacturer-authorized service center. Performing major repairs may void your warranty, even if minor issues can be fixed yourself.
