There you are then! Paul_R says cambelt on 5 years or 70k, so up to you as yours is at least 4 1/2 years old on the 56 plate & if you're only taking it in every 2 years, it'll be well past that at the next service.
So it's brake fluid, filters, oil & possibly new coolant (the one thing I couldn't find any mention of in my service booklet, so replacement every 4-5 years seemed ok to me). And there was something else in the booklet for diesels, but I didn't pay much attention as it's not relevant to me.
And most on here would say that it's best to use fixed interval servicing just to put fresh oil in it every 12 months rather than letting it go for 2 Years. Your choice...
