Jaguar XJ BC (1997–2003)

The Jaguar XJ, in its X308 iteration (1997-2003), stands tall as the epitome of luxury sedans. Fusing enduring British elegance with innovative engineering for its era, these vehicles offer a glimpse into the world of opulence without breaking the bank. Owning an XJ is not merely about possessing a car; it’s about embracing a legacy characterized by charm, sophistication, and a hint of rebellious spirit. Yet, with its prestige comes a responsibility for careful stewardship—especially in the dynamic Kiwi market where unique conditions apply. Let’s explore how to keep your X308 in prime condition.

Parts for the Jaguar XJ BC

Known issues

Timing chain tensioner failure (V8 engines), Nikasil cylinder liner issues (early V8s, less prevalent in NZ due to fuel quality), failing self-levelling suspension (if equipped), rust in sills and around wheel arches, electrical faults (sensors, modules), cooling system leaks.

WOF tips

Check for rust, especially around the sills, wheel arches, and subframe. Ensure all lights function correctly (complex electrical systems can cause issues). Suspension components (ball joints, bushes) should be thoroughly inspected. Brake performance is crucial, and ABS sensors are prone to failure, triggering a WOF failure. SRS warning lights should be checked as it might indicate an issue with the driver or passenger side Airbags, or could be a simple sensor error.

About the Jaguar XJ BC

The X308 XJ signifies a remarkable leap for Jaguar, heralding the introduction of the AJ-V8 engine, which offers both performance and refinement. However, like all cherished classics, thoughtful care is indispensable. Common parts that often need replacement include the timing chain tensioner, especially if the engine has not received timely oil changes, and the self-leveling rear suspension components, which can incur significant repair costs. Regularly scheduled maintenance is crucial; aim for a thorough service every 10,000 km to keep the engine performing optimally.

Watch out for certain issues typical to this era. For instance, the cooling system is prone to wear, typically requiring inspection around the 150,000 km mark. During this service, you'll want to ensure the water pump, thermostat, and radiator hoses are in top shape. It’s worth having a trusted mechanic on hand, especially for electrical components, since gremlins can often appear without warning. To keep your XJ running smoothly, be sure to check out our Cooling category for quality replacement parts. Moreover, regular inspections of the braking system, including brake pads and rotors, ensure safety and performance—our Braking category offers a range of options for you. Lastly, don’t overlook the essential role of filtration; replacing air and oil filters regularly will further enhance your engine's life and efficiency.
