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.^[1][2]

Is the 1.4 HDi reliable?

It is a small diesel that is generally reliable, but with a very well-documented weakness: the injectors tend to lose their seal over time and let diesel escape. The turbo and the EGR valve also fail on a noticeable minority of units, and there are isolated cases of the crankshaft damper pulley failing at very high mileages. The timing belt does not seem to cause more problems than on any diesel of its era if it is changed on time.^[3][4][5]
