The Jaguar XJ40 generation marked a bold step forward for the iconic brand, presenting sleek, angular lines and a fresh design philosophy that redefined luxury saloons. From its early days on New Zealand roads, this model has amazed enthusiasts with its seamless fusion of elegance, comfort, and powerful performance, available with robust inline-6 or exhilarating V12 engine options.
Common issues with the Jaguar XJ40 include electrical problems, cooling system malfunctions, and rust. The self-leveling suspension system can also be problematic. Regular servicing and careful attention to maintenance are essential for keeping an XJ40 in good condition.
When taking a Jaguar XJ40 to a WOF, pay specific attention to rust around the sills, wheel arches, and floor pan. Check that all the lights work and that any electrical systems (such as the self-levelling suspension) have been converted or not functional. The brakes and suspension must be in good working order, with no excessive play or leaks.
The XJ40 is renowned for its opulent interior featuring premium leather, polished wood trim, and a suite of modern comfort features — making each drive a true pleasure. However, maintaining its excellence requires attention to detail, especially regarding the vehicle's essential systems. For instance, common replacement parts due to wear include brake pads, rotors, and suspension components, particularly as the vehicle approaches higher mileage. Regular servicing is key, with a recommended service interval of every 10,000km to ensure your engine, braking, and cooling systems remain in top shape. The cooling system, which may require inspection around 150,000km, includes critical components like the water pump, thermostat, and radiator hoses, all of which can be sourced conveniently from our Cooling category.
Additionally, with known issues surrounding electrical systems and rust, being proactive about maintenance will safeguard your investment. Regular checks of the brakes, engine parts, and engine filtration can help prevent unexpected repairs down the road, ultimately keeping your driving experience both safe and enjoyable. Our Braking, Engine Parts, and Filtration categories provide all the necessary components to ensure your XJ40 continues to perform at its best, embodying the true spirit of Jaguar.
