Why is the central control screen of Audi A4 not lighting up?
3 Answers
The phenomenon of the car's central control screen not lighting up is most likely due to poor line contact. Here is some relevant information about the Audi A4: 1. Introduction: As the first model to introduce the long wheelbase and turbo concept, from B5 to B8, the sales of the A4L have remained consistently strong. The new A4 has abandoned the teardrop design, added the quattro four-wheel drive mode, and features a more fashionable and sporty appearance, with even more outstanding power and handling. The interior of the model is exquisitely crafted, equipped with abundant technological configurations, and offers ample space, making it highly practical among B-class models. 2. Achievements: The Audi A4 produced by FAW-Volkswagen is the first B-class sedan of an international luxury brand in China, filling the gap in the domestic B-class sedan market and strengthening FAW-Volkswagen's leading position in the domestic luxury car market. This was quite significant at the time, and judging from the sales of the Audi A4 in China, it has indeed been successful.
As a friend who has driven an Audi A4 several times, I've also encountered the sudden black screen issue with the center console display. The most common cause is a blown fuse—that tiny component in the fuse box, like the one near the driver's footwell. If it's a fuse problem, simply replacing it with a new one should fix it, possibly due to voltage fluctuations or a short circuit. Sometimes, the screen itself is faulty, especially the LCD screens in older models that can fail over time. It could also be a loose power cable connection; check if the rear connectors are secure. Additionally, software freezing is another factor—Audi's MMI system can occasionally act up, so try holding down the volume knob for a few seconds to reboot the system. A black screen affects navigation and AC settings, but don't rush to the repair shop. Troubleshoot these points yourself first, and only go to the shop if you really can't fix it—it'll save you money.
Let's approach this from a mechanical perspective. When the central control screen doesn't light up, it's often due to a blown fuse. In the Audi A4, the fuse box is typically located in the engine compartment or under the dashboard. Try replacing it with a new one of the same rating. If that doesn't help, check whether the power supply cable to the screen has come loose or is damaged—circuit shorting is quite common, especially during rainy days when humidity is high. Screen hardware failures are also prone to occur in vehicles that have been used for several years. Another possibility is that the infotainment system has crashed, a common issue with Audi models—turning the vehicle off and restarting it might resolve this. In summary, check these aspects, and don't overlook testing the power supply voltage. A depleted car battery can also cause such issues, affecting the overall driving experience, so it's best to address it promptly.
