Why can't Audi CarPlay connect but still charge?

[StLuna]

The reasons why Audi CarPlay cannot connect but still charges are as follows: Damaged data cable: The phone data cable is damaged or broken, or there is foreign matter attached to the metal contact terminals on the USB plug and phone plug, or the surface is oxidized. Internal port damage: The internal USB female port of the car's external USB-HUB is damaged, or the contact metal piece has poor contact with the USB male plug. Loose connection: The connection between the car's main unit and the external USB-HUB is loose. To avoid prolonged oxidation that may lead to poor internal contact, you can repeatedly unplug and replug the two connectors. Car main unit system: The car's main unit system may be malfunctioning. Perform a factory reset, but be sure to back up and transfer important information saved in the system before resetting to prevent data loss.

My Audi had a similar issue before—it could charge but CarPlay wouldn’t connect. It’s likely a cable or phone setting problem. Many USB cables only support charging, not data transfer, which prevents CarPlay from activating, especially with cheap third-party cables. I’d suggest first trying an original or certified data cable to confirm it supports data transfer. Next, check if your iOS is outdated, as Audi’s system often requires the latest version. If CarPlay restrictions are enabled on your phone, that could also block the connection. I’ve seen cases where Bluetooth interference caused issues—try turning off your phone’s Bluetooth or reconnecting to the car’s system. Start with the basics: swap the cable, restart your phone and infotainment system, and update the software. If that doesn’t work, a dealership visit might be needed to check the car’s USB port or software bugs. During routine maintenance, remind the technician to inspect these settings—it can save you a lot of headaches later.
