Multiple linked computers
Modern EVs rely on control modules communicating across the vehicle. One fault can trigger warnings in several systems.
EV & hybrid diagnostics
Modern EV faults need proper diagnosis, not guesswork.
Electric and hybrid vehicles are now networks of ECUs, sensors, high-voltage components and control modules. A fault code is only the start. The skill is proving what caused it.

Why diagnosis matters
EV and hybrid faults are no longer simple mechanical problems.
One warning light can involve the battery management system, inverter, onboard charger, DC-DC converter, thermal system, wiring network and several ECUs talking to each other. Replacing parts before testing properly can become very expensive, very quickly.
Live data, not just codes
We look at readings, states, voltages, temperatures and module behaviour to understand what is happening.
High-voltage aware
Battery and high-voltage systems need controlled, careful testing with the right equipment and knowledge.
How it works
A clear three-step route from warning light to repair.
We make the first step simple: diagnose the vehicle properly, explain the fault route, then quote a fixed repair price before any repair work starts.
Diagnostic visit - £119
We come to the vehicle and run a specialist diagnostic check using professional tools, live data and EV/hybrid system knowledge.
Clear solution and fixed price
You get a plain-English explanation of what we found, what needs to happen next and a fixed cost before repair work begins.
No fix, no fee approach
Where an agreed repair route is accepted, we work with a no-fix/no-fee mindset on eligible repairs. Terms and conditions apply.
What we diagnose
Battery, charging, hybrid and high-voltage faults.
- EV or hybrid warning lights and reduced power.
- Vehicles that will not charge or stop charging.
- Battery management system, module and sensor faults.
- Inverter, onboard charger, DC-DC and high-voltage component concerns.
- Intermittent faults, communication errors and complex electrical problems.
Top-end tools. Real interpretation.
Professional tools are only useful when the data is understood. We combine specialist equipment with fault-finding experience so the next step is based on evidence.

Why customers call us
Because the wrong diagnosis costs more than the diagnostic.
A controlled first step before replacing expensive components.
You know the cost before repair work starts.
Ideal when the vehicle has warnings, reduced power or charging problems.
