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.^[1][2][3]

Is the TDV6 / SDV6 reliable?

The Land Rover and Jaguar TDV6/SDV6 diesel V6 engines, shared with Peugeot and Citroën, have a serious documented fault: crankshaft and main bearing shells on the 3.0, and the belt-driven oil pump on the 2.7. Insist on a service history and weigh up the repair cost before buying.^[4][5][6]
