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 1.9 TDI reliable?

It depends a lot on the version. The rotary pump (1996-2003, codes ALH and AGR among others) has a reputation for great durability. The unit injector system (1999-2010) improves performance and emissions, but has more documented faults: dual-mass flywheel, turbo, EGR valve and, above all in the 105 hp version, cases of broken big-end bearings.^{[4][5][6][7][8][9][10]}
