2015 Jaguar XF 2.2L Diesel · R4 BUH

The 2.0L diesel engine timing chain stretches due to oil dilution (reaching 6-7% trigger levels). This is often called "timing chain slap" and can lead to catastrophic engine failure if the chain snaps.

The water pumps on 3.0 supercharged V6 and 5.0 V8 engines are prone to premature failure, sometimes lasting less than 20,000 miles. Coolant enters the bearing housing and corrodes it, causing the impeller shaft seal to wear and leak coolant externally.

The wiring loom running into the boot flexes every time the boot is opened and closed, eventually causing the wires to fatigue and break. This disables the rear camera, boot lights, number plate lights and sometimes the rear sensors.
