Is the 1.6 and 2.0 MultiJet II reliable?

The 1.6 and 2.0 MultiJet II are Fiat diesels with a solid mechanical base, but with known faults worth checking before you buy: the timing belt tensioner may need replacing before the official interval, the EGR valve clogs with urban use, the particulate filter becomes saturated if there are not enough long journeys, and the dual-mass flywheel and the occasional injector wear with mileage. There is no officially recognised recall campaign for these faults.^[1][2][3][4]

Is the 2.0/2.2 D-4D reliable?

No: the 2.0/2.2 D-4D family is among the most problematic Toyota diesels. The 2.2 block (2AD-FTV and 2AD-FHV D-CAT) has a large number of cases of warped cylinder head gaskets and oil consumption or dilution in the Avensis, RAV4, Auris, Corolla Verso and Verso; the EGR valve and injectors fail frequently across the whole family, and the D-CAT filter clogs up if the car is not driven regularly on open roads.^[5][6][7][8]
