Land Rover Jaguar Start-Stop Battery Sensor BJ32-10C679-AE LR038720 LR038721

If your Land Rover or Jaguar vehicle experiences frequent Start-Stop system failures, dashboard shows “Battery charging” or “Start-Stop unavailable,” and the battery condition is good, the issue is likely the Start-Stop battery sensor (BMS sensor) aging or damage, causing inaccurate battery status readings. This sensor, in normal operation, monitors real-time battery voltage, current, and temperature and transmits data to the powertrain control unit to precisely control Start-Stop function, charging strategy, and electrical distribution. Compatible with OEM numbers LR038720, LR038721, BJ32-10C679-AE, LE026038, C2Z16597; fits Land Rover Range Rover, Range Rover Sport, Discovery, Velar and Jaguar F-PACE, XE, XF, etc. Installation note: disconnect the battery negative terminal first; after installing the sensor, use a professional diagnostic tool to reset or match the BMS, otherwise the new sensor may not be recognized by the system.
