How does this differ from the main Mégane entry?
This covers the third generation specifically. Our history records the model under several designations, so check both.
How does the 1.5 dCi respond?
It is a small-displacement engine, so the relative gain in flexibility is noticeable, particularly when overtaking or with the car loaded.
Is the work reversible?
Yes. We always keep the original ECU file, so the car can be returned to its factory configuration.
