How does the 1.5 dCi respond?
It gains mainly in mid-range flexibility, which is where a compact hatchback spends most of its time. It is a robust engine and the map is kept measured.
Do you cover the 2.0T petrol?
Yes, it is present in our catalogue. Being turbocharged, it offers more headroom than the diesels.
How do I know which ECU mine has?
It depends on the year and engine: EDC16C3, SID305/6, SID310 or EMS3155 are all possible. Send us the reference and we will confirm.
