Mercedes-Benz Viano 2.0 CDI 109hp Remap

The Mercedes-Benz Viano 2.0 CDI 109hp is a 2.0L turbocharged diesel engine producing 109 BHP and 270 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 180 BHP and 400 Nm — a gain of around 71 BHP (65%) and 130 Nm (48%).

This engine scores highly for remap suitability, with gains weighted towards peak power — the improvement is most noticeable at higher RPM. The tuning headroom is classified as high, based on the percentage gain available from the factory output.

Considerations: Large torque increase: drivetrain condition (clutch/gearbox) becomes more important at this level.. Older diesel: injector, turbo and intake condition can affect results; ensure maintenance is up to date.

Fuel economy note: economy gains unlikely at full power; depends on driving style.

All figures shown are typical estimates based on aggregated Stage 1 data for this engine variant. Actual results depend on vehicle condition, mileage, and the chosen tuning method. We recommend discussing your specific vehicle with a qualified remap professional.
