Why can't my phone charge in the Audi Q2L?

Audi Q2L phone charging failure can be divided into two situations: connecting the phone via the USB port with no charging display; or connecting the phone via the USB port with a charging display, but the phone doesn't actually charge. No charging display on the phone: The vehicle's USB port fuse may be blown (check the corresponding fuse in the vehicle manual and replace the spare fuse if it's melted). The phone's charging port spring may be loose, causing poor contact. Charging display appears, but phone doesn't charge: If this occurs, it indicates that the USB port is only for reading USB drive data, not for phone charging. Check the USB port's application scope in the vehicle manual.
As an Audi Q2L owner who frequently drives for ride-hailing services, I've dealt with quite a few such issues. Ninety percent of charging failures stem from physical contact problems: First, check if dust is blocking the charging contacts in the car's original USB port, especially the rear charging ports which are prone to snack debris intrusion. Loose or aged/frayed cable connectors are also common—try switching to an original factory cable. If the issue lies with a cigarette lighter adapter charger, inspect whether the adapter shows signs of scorching or discoloration—once I used a substandard car charger that blew a fuse. By the way, the vehicle needs to re-recognize charging devices after engine shutdown, so it's advisable to plug/unplug while the ignition is on. Unstable onboard voltage can also trigger protection mechanisms; next time you start the car, use a USB voltage tester to check if the output remains steady. Don't rush to the dealership—these self-checks can save you hundreds in diagnostic fees.
Just helped my neighbor with this issue last week. When dealing with Q2L charging failures, always start with the basics: check if the phone's charging port is clogged with dust causing poor contact—I usually clean it with alcohol-soaked cotton wrapped around a toothpick. If it charges when using a different socket, then the issue is with the car. Pay special attention to the USB port in the armrest, as it tends to accumulate coin debris—use a strong flashlight to inspect and clean it. If the screen displays 'Charging device not supported' while charging, it's likely an incompatible cable. The car's original USB module only provides 5V/1A, which is insufficient for modern fast-charging phones, and prolonged overloading can easily damage the port. Rear passengers yanking the cable forcefully may also cause the female port to desolder, requiring the center console to be disassembled to inspect the solder joints—though this step is best left to a professional.
