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 2.0 Ingenium diésel reliable?

The 2.0 Ingenium diesel is the four-cylinder diesel engine that Jaguar Land Rover designed from scratch and has fitted since 2015 to the Range Rover Evoque, the Discovery Sport and several Jaguars. Several sources repeatedly document timing chain stretch, balance shaft wear, turbo failures and fuel dilution of the oil, so it is worth checking thoroughly before buying.^[5][6]
