Is the 1.6 CDTI reliable?

The Opel/Vauxhall 1.6 CDTI (2013-2020, 95-160 hp) has no design fault acknowledged by the manufacturer, but it has built up reports of early wear of the timing chain and its tensioner, two episodes (2016 and 2018) of German investigation into a possible EGR valve shut-off, and AdBlue system faults on its Euro 6 versions.^{[1][2][3][4][5][6][7]}

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.^{[8][9][10][11]}
