Citroen C4 Cactus 1.5 BlueHDI Stage 1 Remap
On Citroen C4 Cactus 1.5 BlueHDI diesel engines a Stage 1 remap recalibrates the fuel quantity, injection timing, boost pressure and torque limiter maps. No hardware is changed and the original software is backed up. The same engine is sold with different stock outputs across generations, so the gain depends on your version.
It depends on the generation and the stock output. 1.5 BlueHDI engines with 102–120 bhp reach 145–160 bhp with a Stage 1 remap; the largest gain is +43 bhp (1.5 BlueHDI 102hp). Pick your version in the table below.

How a Stage 1 remap works on the Citroen C4 Cactus 1.5 BlueHDI
Stage 1 recalibrates rail pressure, injection and boost. The gain is especially clear on the 100 hp version, since its hardware is largely shared with the 130 hp. Emissions systems are preserved; on EAT8 automatic cars the torque limit is respected.
Pre-remap checklist
- AdBlue system: pump, injector and NOx sensors; AdBlue faults are frequent on this engine.
- DPF load.
- EGR valve cleanliness.
- Oil service; the belt runs in oil.
On a car with an AdBlue fault, diagnosis comes first; the "engine will not start" countdown is handled within the legal framework.
