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 BMW M47 reliable?

The BMW M47 (1998-2007, a 4-cylinder diesel fitted to the 3 Series E46/E90, 1 Series E87, 5 Series E60, X3 E83, the Rover 75 and the Land Rover Freelander) is solid in its basic mechanicals, but the common rail versions, built since 2001, carry a serious and well-documented problem: the intake manifold swirl flaps can break and enter the cylinder, with a risk of engine damage. The turbo and injectors also account for known faults.^{[7][8][9][10]}
