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 2.3 VR5 (V5) reliable?

The 2.3-litre VR5 is a naturally aspirated five-cylinder with the timing chain at the rear of the engine. Gebrauchtwagenberater rates it as a buy with no known problems in the Golf IV, but in the Bora it warns that the chain sometimes stretches; AutoHints adds the coils and the plastic coolant parts as points to watch.^[4][5][6][7]
