About the Mercedes-Benz OM611 / OM646 / OM647 CDI (pre-2008 200 / 220 / 270 / 320 CDI)
These are the first-generation common-rail diesels of the W203 C-Class, W210 and W211 E-Class, Vito, Sprinter and ML. Known for their durability, they respond reliably to a remap even at high mileage.
How a Stage 1 remap works on the Mercedes-Benz C W203 220 CDI 136hp
Stage 1 recalibrates injection duration, rail pressure and boost. With simple emissions hardware on this generation the calibration focuses directly on the engine; the mid-range torque gain is clear.
Pre-remap checklist
- Injector sealing and injector seals (burning smell and carbon traces).
- Oil leaks at the turbo and intake hoses.
- EGR valve cleanliness.
- Automatic gearbox oil and filter service.
