Is the 2.2 JTDm Multijet II reliable?

Alfa Romeo's 2.2 diesel (Giulia and Stelvio) has a good reputation: a German guide rates it as very reliable and a 210 hp Stelvio covered 100,000 km in a test without any faults. The sources mainly record leaks and oil consumption, the odd particulate filter and EGR case, and two one-off campaigns: the fuel filter gasket (2018 Giulia) and the alternator cable next to the EGR pipe (2017-2018 Stelvio).^{[1][2][3][4][5][6]}

Is the D4/D5 reliable?

The Volvo D5/D4 covers two different engines: the classic 5-cylinder (2001-2016, D5244T/D5204) and the 4-cylinder VEA (D4204T, from 2013). On the former, several owners document the auxiliary belt breaking and taking the timing belt with it, destroying the engine; on the VEA the most common problems are the EGR, the DPF and oil consumption that can damage the turbo from 90,000-150,000 km. Neither is an engine to buy without checking its service history.^{[7][8][9][10]}
