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 1.6 and 2.0 8v EA827 reliable?

Simple, naturally aspirated petrol engines that, according to the sources, last a long time with regular maintenance. Gebrauchtwagenberater describes the 8-valve 1.6 as old-fashioned but reliable, and the 102 hp 1.6 MPI as even more reliable than the 1.4 16v. Watch the timing belt with the water pump, coolant leaks, oil consumption (especially on the 2.0) and idle and sensor faults.^[3][4][5][6]
