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]
