Why is the screen and buttons of the Audi Q5 not lighting up?
3 Answers
It might be due to accidentally pressing the IC button on the MMI, which caused the screen to turn off. Here is the relevant introduction to the Audi Q5's onboard display: 1. Detailed Introduction: There are two types: one is a TV placed in the passenger compartment for viewing, essentially an onboard TV, and the other is a small-sized onboard display. Generally, it has two video inputs—one can be connected to an onboard DVD, and the other can be connected to a reversing camera. Some also come with MP5 video playback and Bluetooth functionality, making them usable on similar automotive motion tools. 2. Specifications: Basic specifications of onboard displays must include dustproof and shockproof features. In terms of temperature, they must be able to withstand extreme temperature differences from -30°C to +85°C, and even up to 120°C. This is because the liquid crystal in LCD panels can freeze in low-temperature environments, leading to the inability to display images properly or complete destruction of display capability. 3. Product Features: High clarity with no color distortion, providing excellent image quality; more convenient operation with a remote control; simple and easy installation without damaging the vehicle body; customized for onboard video display with excellent shock resistance; smooth image flow without ghosting.
I've driven quite a few cars, including luxury SUVs like the Audi Q5, and I've encountered the issue of all screen buttons not lighting up several times. The most common problem lies in the electrical system, such as a blown fuse—this component protects the circuit and melts when the current is too high, causing the entire infotainment system to go black. First, check the fuse box inside the car, usually located in the panel next to the driver's seat or under the glove compartment. Look for the MMI or Infotainment label and test it with a multimeter. If the fuse is fine, then other factors need to be investigated, such as insufficient power supply due to low battery voltage, which often occurs during cold starts, or a faulty control unit where the main module might be damaged, requiring a professional scan with a diagnostic tool at a repair shop. If it can't be fixed in one go, I recommend not disassembling it yourself—Audi's wiring is complex and prone to causing more issues. Contacting an authorized dealer is the safest option, as prolonged issues might even affect the air conditioning or navigation functions. Regular maintenance of the electrical components is crucial.
My Audi Q5 has been running for over a year, and recently the screen buttons suddenly went black, leaving me flustered. After searching online for quite a while, I found that this is likely due to a system software crash. Audi's MMI occasionally freezes, just like how a phone needs a reboot. You can try a hard restart: turn off the engine, wait ten minutes for the system to cool down, then restart; or press and hold the volume knob and navigation button for about ten seconds to force a reset. If that doesn't work, it might be a deeper hardware issue, such as a short circuit or loose connection. Last time I tried and it didn’t work—the repair shop found it was an entertainment module failure, and replacing a small part cost a few hundred bucks. Another possibility is insufficient power due to an aging battery, especially when the voltage fluctuates during startup. Regularly checking the dashboard warning lights before driving can help prevent this.
