Is a remap worthwhile on a compact MPV?
Yes, especially if the car is regularly full. The extra mid-range torque is most noticeable with passengers and luggage on board.
What is BlueEfficiency?
It is the efficiency-focused calibration applied to several diesel variants of the range. Those versions are covered in our catalogue.
Is the work reversible?
Yes. We always keep the original ECU file, so the car can be returned to its factory configuration.
