Is the BMW B47 reliable?

The BMW B47 (since 2014, successor to the N47) improves the timing chain tensioner, guides and oil supply and greatly reduces the failure rate of its predecessor, but it is not free of problems: the EGR cooler has been the subject of several BMW technical campaigns for engine fire risk since 2018, and the turbo and particulate filter need careful maintenance.^[1][2][3][4]

Is the 2.2 TD4 / SD4 reliable?

This is the 2.2-litre diesel of the Freelander 2, the first Evoque, the 2014-2015 Discovery Sport and the Jaguar XF 2.2D. The sources consulted do not describe it as a problematic engine, but they point to three things: the EGR cooler, the DPF in urban use, and replacing the belt along with the water pump.^[5][6][7]
