Is the 2.2/2.5 dCi reliable?

The 2.2 dCi (YD22DDT/YD22DDTi) and 2.5 dCi (YD25DDTi) are diesels of Nissan's own design, with a timing chain, fitted to the Almera, Primera, X-Trail, Navara and Pathfinder between 2000 and 2015. The turbo and its intercooler are the best-documented fault, above all on the X-Trail, along with injector failures; the timing chain, on the other hand, gives hardly any trouble according to the reliability reports consulted.[1][2][3]

Is the 2.3 dCi (M9T) reliable?

The 2.3 dCi M9T is a van diesel with good durability if maintenance is kept up. The weak points cited are the EGR and the turbo, the injectors, and the particulate filter in urban use; the sources are mostly opinion websites.[4][5]
