Is the BMW N20 reliable?

The BMW N20 (2011-2017) was the first turbocharged four-cylinder with which BMW replaced its naturally aspirated six-cylinders in models such as the 320i, 328i and X3, and it is generally mechanically sound. Its best-documented weak point is the timing chain guides and tensioner on units built before 2015; oil leaks, the electric water pump and, to a lesser extent, the turbo and the high-pressure fuel pump are also known issues.^[1][2]

Is the 2.2 Ecotec gasolina reliable?

This is the 2.2 petrol engine producing 147 to 155 hp in the Astra G, Zafira, Vectra and Signum. Its documented weak point is the timing chain, which stretches and can end in serious engine damage; the 2.2 Direct adds a high-pressure pump prone to failure.^[3][4][5]
