What is MultiAir?
It is the group's variable valve actuation system, fitted to the 1.4 turbocharged petrol. It is present in our catalogue for this model.
Which engine gains most?
The 2.0 MultiJet diesel in absolute torque, though the 1.4 turbocharged petrol also responds strongly for its displacement.
Is the work reversible?
Yes. We always keep the original ECU file, so the car can be returned to its factory configuration.
