Is the BMW N52 / N53 reliable?

The BMW N52 (2004-2015, port injection) is considered very reliable for a BMW, with known weak points (electric water pump, oil seals, valve cover). The N53 (2007-2013, direct injection) adds piezoelectric injectors prone to failure, which make it more expensive to maintain.^[1][2][3]

Is the 2.0 16v F4R and F4RT reliable?

In the sources we consulted, the 2.0-litre F4R and F4RT show no engine-destroying design faults, but the timing belt must be changed on time, and the coils (RS) and the variable valve timing pulley appear as weak points. We have found no reliable sources on oil consumption or big-end bearings.^[4][5][6][7]
