When something on an EV isn't right - a warning light, a charging refusal, a range anomaly, a missing function - you need a proper diagnostic specialist with the right tools, not a generic code reader. We've invested in manufacturer-level diagnostic equipment that talks to every module on the EV's CAN bus, not just the engine ECU.
We diagnose everything from simple stored fault codes to communication breakdowns between modules, HV system faults, charging issues, and battery management problems. We trace wiring with proper schematics and oscilloscopes when needed, and we can program / code modules where the fault calls for it.
If you've been quoted thousands by a main dealer and want a second opinion before you commit, bring it to us. We'll diagnose the actual fault and tell you straight what's needed - no upselling, no fear-tactics.
