Your EV is software — we speak it fluently
A modern EV is a computer on wheels. We update firmware, reprogram modules and reflash control units with manufacturer-grade tooling — unlocking fixes, features and performance.
An electric vehicle is defined far more by its code than its mechanicals. Dozens of control units govern the battery, the motors, the charging system, the driver assistance features and the cabin — and manufacturers continuously refine that software to improve range, smooth performance, fix bugs and add capability. Yet many of these updates never reach the car, either because the owner never visits a dealer or because over-the-air delivery is limited on their model. We make sure your EV is running the software it was always meant to.
Our workshop uses manufacturer-grade diagnostic and programming platforms, the same class of tooling the franchised dealers rely on. That lets us safely apply official firmware updates, reprogram individual control modules, code new components after a repair and reflash ECUs when a fault demands it. Every reflash is performed with a stabilised power supply and a verified backup, because an interrupted software write can brick a module — this is precisely the kind of work that should never be attempted with consumer-grade gadgets or guesswork.
Software work we perform
- Official firmware and control-module updates
- ECU reflashing to resolve driveability and charging faults
- Module coding and configuration after component replacement
- Battery-management and thermal-strategy updates
- Driver-assistance and infotainment software refreshes
- Clearing and root-causing persistent fault codes
Fixes you can feel
Software is not abstract — the right update can transform how your car behaves. We regularly see firmware revisions that improve charging speed and reliability, smooth out low-speed motor response, recalibrate range estimation, resolve phantom warning lights and sharpen the behaviour of driver-assistance systems. When an EV develops an intermittent gremlin that no mechanical inspection can explain, the cause is very often a known software issue with an official fix waiting to be applied.
Safe, certified, reversible
Reprogramming a vehicle is high-stakes work, and we treat it with the seriousness it deserves. Before any write we capture the existing configuration, connect a dedicated power supply to hold a rock-steady voltage, and confirm the correct official software for your exact build. After the update we verify every affected module, road-test where appropriate, and document precisely what changed. You leave with a car that is genuinely up to date — and a record of exactly what we did and why.
If your EV feels behind the times, throws an unexplained fault, or has just had a component replaced, book a software service and we will bring its brain fully up to spec.
EV Software & ECU Reflashing questions
Many models only deliver a subset of updates over the air, and some require a wired connection for module coding or major reflashes. We apply the full range of official updates, including those that never arrive wirelessly.
Yes, when done correctly. We use manufacturer-grade tooling, a stabilised power supply and verified official software, with a backup of your existing configuration before any change.
In most cases, yes. Many replacement components must be coded to the vehicle before they function correctly, and we can perform that configuration.
