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 2.2 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.^[4][5][6]
