How does this differ from the main Mégane entry?
This covers the third generation specifically. Our history records the model under several designations, so it is worth checking both entries.
How does the 1.5 dCi respond?
It gains mainly in mid-range flexibility. It is a robust engine and the map is kept measured to preserve that reliability.
Do you cover the TCe petrol units?
Yes, the 1.4 and 2.0 TCe are present in our catalogue. Being turbocharged, they offer more headroom than the diesels.
