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 2.0 dCi reliable?

The 2.0 dCi (M9R) is a Renault-Nissan Alliance diesel with known, well-documented weak points: the turbo and the EGR valve fail relatively often, the particulate filter clogs up in urban use, and there are cases of injectors and even the timing chain failing earlier than expected in several of the models that use it.^{[7][8][9][10]}
