🔋 Range Rover Sport PHEV Charging Fault – Not Every Battery Needs Replacing! 🔋
This Range Rover Sport PHEV came to us after being assessed elsewhere, where a DC-DC charging unit had been recommended.
As always, we carried out our own diagnostic assessment before replacing any parts.
What did we find?
The fault wasn’t the DC-DC converter at all.
Our testing identified a problem within the high-voltage battery contactors, caused by a known software-related issue within the Battery Energy Control Module (BECM).
If you ask Land Rover, the official repair route is often a complete replacement high-voltage battery. 💷💷💷
For many owners, that’s a frighteningly expensive repair.
Instead, we’ve sourced a specialist company that repairs these batteries. They strip and repair the battery internally before carrying out extensive testing on a dedicated simulator rig to ensure it performs correctly before being returned with a warranty.
Today we safely removed the high-voltage battery and prepared it for shipping.
With a bit of luck, this Range Rover will be back on the road and charging normally by the end of next week.
This is a perfect example of why diagnostics matter.
Anyone can fit parts.
The real skill is identifying the actual cause of the fault and finding the most appropriate repair solution.
✅ Correct diagnosis
✅ Sustainable repair
✅ Potentially thousands saved compared to replacement
✅ Another vehicle kept on the road
Testing, Not Guessing.
Have you been told your hybrid or EV needs a complete battery? It may be worth getting a second opinion before signing on the dotted line.
