Is the BMW N47 reliable?

The BMW N47 (2007-2016, including its MINI derivatives N47C16/N47C20) is mechanically sound in the basics, but it carries a serious, well-documented design flaw: the rear timing chain wears or breaks prematurely on many units, especially those built between 2007 and 2009, with repairs from €1,500 to over €8,000 if the engine ends up damaged. Without a clear timing history, great caution is needed.^[1][2][3][4]

Is the 1.4 TDI reliable?

It depends on the generation. The unit-injector one (1999-2010) calls for watching the timing belt - which also drives the unit injector pumps - the water pump, the turbo and the EGR, with a DPF only on the last BlueMotion/Ecomotive versions. The later EA288 (2014-2019) is not singled out by dieselgate, which according to the sources consulted was limited to the EA189, but it shares the need to watch the belt, turbo, EGR and DPF.^[5][6][7]
