This model uses a timing chain rather than a belt, so there is no scheduled replacement. Chains can still stretch at high mileage, a rattle on cold start is the classic warning, and the range above is what a replacement costs if it ever needs doing.
Prices vary between the petrol and diesel versions, diesels carry glow plugs, a DPF and usually cost slightly more on servicing, petrols have spark plugs on a fixed schedule. The ranges above span both.
