Can you remap Citroen BlueHDi engines?

Yes, BlueHDi diesel engines respond very well to remapping with typical gains of 25-35% more power and torque.

Do you tune Citroen vans?

Absolutely. The Dispatch, Relay and Berlingo are popular for commercial tuning. Improved torque makes loaded driving much easier.

What about PureTech petrol engines?

PureTech engines, especially the 1.2 turbo, deliver excellent gains. Award-winning engine technology that responds brilliantly to tuning.

Our Services for Citroen

Citroen's award-winning PureTech 1.2 three-cylinder turbo gains 25-35bhp through optimised boost pressure and fuelling — transforming the C3 and C4 from efficient commuters into genuinely punchy cars. BlueHDi 1.5 and 2.0 diesels see 25-40bhp with significantly improved low-end torque. Commercial vehicles like the Dispatch and Relay benefit from improved loaded pulling power through targeted torque curve optimisation.

Citroen's BlueHDi diesels are already efficient, but our economy calibrations extract 10-15% more from the 1.5 and 2.0 units through optimised injection timing, reduced turbo lag at cruise speeds, and refined EGR strategies. Especially popular with Dispatch and Berlingo van operators looking to reduce fleet fuel costs — the savings compound quickly across high-mileage commercial use.

Citroen's PSA diesel engines use an Eolys additive-based DPF system unique to the French manufacturer, requiring correct additive levels and specific regeneration conditions. The 1.6 BlueHDi in C3 and C4 models is particularly prone to DPF issues from short urban trips. We diagnose Eolys additive levels, differential pressure sensor faults, and EGR valve carbon fouling through Citroen-specific diagnostic protocols.

Citroen's BlueHDi SCR system — shared across the Stellantis group — uses a dosing module and dual NOx sensors that can develop faults from crystallisation, injector blockage, and quality sensor degradation. The Dispatch and Relay commercial vehicles are particularly susceptible due to high idle time and urban driving patterns. We diagnose the specific fault and apply targeted software solutions.
