Hybrid Range Rover Diagnostic Report
This vehicle was booked in for a Range Rover hybrid battery repair after a HV warning light and reduced-range message appeared on the dashboard. Initial scanning revealed fault codes P0A1F-49, P0AF9-00, P0B3F-00, P0494-16 and P0AFA-16. With no visible external battery damage and the high-voltage pack voltage stable at around 260 V, technicians moved to component-level testing. They discovered the 12-V batteries were severely discharged (~3.5 V) and then isolated a fault in a cell supervision circuit board inside the HV battery pack. The cell-board fault triggered the warnings and range drop.
Hybrid Range Rover Repairs
The repair process included removal of the HV battery pack, replacement or repair of the faulty cell supervision circuit board (in this case affecting all six boards for optimal result), addition of reinforcing spacers for future durability, re-assembly, and thorough road-testing to validate the fix.
Resolution
Following completion of the repair, the Range Rover hybrid battery repair was successful: the warning light cleared, the reduced-range message disappeared, the hybrid EV mode function restored, and the vehicle returned to the customer in fully operational condition, at a fraction of the cost of a full battery replacement.
