Is the BMW N13 reliable?

The BMW N13 (2011-2016), BMW's first turbocharged four-cylinder in three decades, powered the 114i, 116i, 118i and 120i (F20/F21) and the 316i (F30). It derives from the Prince engine developed with PSA, the same origin as the 1.6 THP. In 2013 BMW issued a technical service bulletin over timing chain and tensioner wear; oil consumption and carbon build-up on the injectors are other weak points shared with that family.^[1][2][3]

Is the 1.2 12V reliable?

The 1.2 12V is a simple, low-power, naturally aspirated three-cylinder engine (54-70 hp), with two documented design faults: the timing chain tensioner, which can end up destroying the engine, and -on the Volkswagen Polo IV- a catalytic converter too close to the cylinder head that can burn the exhaust valves. Ignition coil failures are also common, and there are isolated cases of oil consumption and vibration.^{[4][5][6][7][8]}
