BMW X5 4x4 inactive warning with ABS light and unstable navigation/cd player on BMW X5

Some BMW X5 owners report experiencing a 4x4 inactive warning along with the ABS light, which may indicate underlying issues such as a failed transfer case servo motor. Additionally, the ABS light suggests a disabled anti-lock braking system, potentially caused by a malfunctioning wheel speed sensor. Furthermore, unstable behavior of the navigation and CD player could be linked to electrical problems, such as alternator issues. To address these concerns, it is advisable for owners to have the transfer case servo motor and wheel speed sensor checked and repaired, as well as to investigate the alternator for stable electrical supply. If these measures do not resolve the issues, consulting a BMW specialist for a comprehensive diagnosis and repair is recommended to ensure the vehicle's safety and functionality.
