The 2 L 4-cylinder in the Volvo V40 is a solid, mid-range diesel — enough torque to be genuinely useful, calibrated cautiously enough to survive every market where the manufacturer sells it. The result is a factory map that's deliberately muted. Most of the real-world gain we make on a remap comes from recovering that headroom safely.
Our dyno-developed map for the Volvo V40 adds an average of 10 kW (18%) at the wheels and 53 Nm (19%) of engine torque. That's the target band we work towards on this engine — meaningful gains you feel every time you pull out to overtake or climb a grade, without pushing the injectors, turbo or transmission anywhere near their limits.
In practical terms, that works out to around 5 fewer tanks of diesel over 40,000 km. At a typical 15,000 km annual mileage, most Volvo V40 owners save roughly 126 L and $151 per year at the pump — purely from improved combustion efficiency at part-throttle, where diesels spend most of their time.
This Volvo V40 variant ran from 2015–2018 — long enough that the factory calibration was revised more than once during that run. Before we flash anything, we identify the exact year and ECU revision, read and back up the original file, and then apply the map built for that specific version.
