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 TDV6 / SDV6 reliable?

The Land Rover and Jaguar TDV6/SDV6 diesel V6 engines, shared with Peugeot and Citroën, have a serious documented fault: crankshaft and main bearing shells on the 3.0, and the belt-driven oil pump on the 2.7. Insist on a service history and weigh up the repair cost before buying.^[7][8][9]
