The Jaguar XJ (XJ40) represents a remarkable evolution within the storied XJ lineage. Produced from 1986 to 1994, the earlier models (1986-1989) are swiftly becoming sought-after classics, especially among Kiwi owners who appreciate the blend of British elegance and engineering precision. This guide delves into the unique attributes of these XJ40s, offering essential information to help you maintain and enjoy this iconic vehicle.
Electrical gremlins are notorious in XJ40s, stemming from complex wiring and now-aging components. Suspension issues, particularly with the self-leveling system (if equipped), are common. Rust can be a problem, though less so than earlier Jaguars. Leaks from the engine and transmission are typical of older vehicles.
WOF inspectors will pay close attention to rust in the sills, floor, and suspension mounting points. The condition of the brakes and suspension is paramount, especially the functionality of the self-leveling system (if fitted). Electrical systems need to function correctly, as even non-critical faults can lead to a WOF failure. Check that all lights and signals are operating correctly.
The Jaguar XJ40 not only signifies a departure from traditional Jaguar styling but also remains rooted in the brand's core values of luxury, comfort, and performance. Renowned for its smooth ride and refined interior, this model requires attentive care to remain reliable through the years. Regular maintenance is crucial, with service intervals that suggest particular focus on the vehicle's braking, cooling, and electrical systems. For instance, the cooling system requires inspection around 150,000 km—ensuring that the water pump, thermostat, and radiator are functioning optimally is vital for preventing overheating.

Common issues such as electrical gremlins, including wiring faults, can plague these classic vehicles due to aging components. The self-leveling suspension system, if equipped, may also require routine inspections. Fortunately, parts like brake pads and rotors can be changed easily to maintain excellent braking performance, ensuring safety at every turn.
