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 1.9 D (XUD and DW8) reliable?

Simple, long-lived indirect-injection diesels with uncommon faults. The points to watch are the cylinder head gasket, the connecting rod on the 1996-1999 1.9 TD (rare but destructive), the accessory belt on cars built up to mid-1999, and oil or injection pump leaks at high mileage.^[5][6][7][8]
