Is the BMW M47 reliable?

The BMW M47 (1998-2007, a 4-cylinder diesel fitted to the 3 Series E46/E90, 1 Series E87, 5 Series E60, X3 E83, the Rover 75 and the Land Rover Freelander) is solid in its basic mechanicals, but the common rail versions, built since 2001, carry a serious and well-documented problem: the intake manifold swirl flaps can break and enter the cylinder, with a risk of engine damage. The turbo and injectors also account for known faults.[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]
