BMW 328i xDrive AUX port remains active despite no device connected on BMW 328i xDrive

Some BMW 328i xDrive owners report experiencing issues with the AUX-IN port remaining active even when no device is connected. This problem may be attributed to physical damage or loose wires affecting the USB and AUX connectors, while other functions like CD and Tuner remain operational. Additionally, some owners find that utilizing an alternative USB port, located at the upper-left of the glovebox opening, can resolve the issue if the primary port is malfunctioning. It is advisable for owners facing these problems to inspect the connectors for damage and consider using the secondary port if available.
