EV diagnostics / charging system repair
Specialist diagnostics and repair support for an EV-converted Land Rover Defender by Twisted. The vehicle arrived with a charging fault, and VASS traced the issue to the onboard charger, coordinated the repair process, reinstalled the system and returned the vehicle to full working order.
Discuss a related projectProject introduction
The client came to VASS with an EV-converted Land Rover Defender by Twisted that had developed a charging issue. The goal was to diagnose the fault properly, confirm the root cause, and return the vehicle to reliable working order without unnecessary guesswork or parts replacement.
VASS was asked to carry out a full diagnostic investigation into the Defender’s charging issue and identify why the vehicle was no longer charging correctly. The work required an understanding of EV charging systems, high-voltage safety, onboard charger behaviour and how the converted vehicle systems interacted.

Commissioning & result
The onboard charger was repaired, reinstalled and the system was successfully recommissioned. The Defender was returned to full working health, allowing the client to use and charge the vehicle again with confidence.
For similar programmes
This project shows that VASS can support owners and workshops with existing EV conversions, even when the original conversion was completed elsewhere. Many EV conversion issues are not solved by replacing parts at random; they require structured diagnostics, high-voltage knowledge and an understanding of how the full vehicle system works.
