The 2004 Jaguar XJR: A Mechanic’s Perspective on Ownership and Maintenance

The Jaguar XJR, especially the 2004 model within the X350 generation, represents a unique blend of British luxury and exhilarating performance. For enthusiasts and potential owners considering a pre-owned XJR, understanding the realities of ownership, particularly from a maintenance standpoint, is crucial. While these machines offer a driving experience few can match, like any high-performance vehicle, they require diligent care, especially as they age.

Drawing from discussions amongst owners, it’s clear that acquiring a 2004 Jaguar Xjr can be an exciting but potentially demanding endeavor. One owner’s experience highlights this perfectly: purchasing a “dirt cheap” XJR with a clean Carfax report, only to uncover a series of maintenance needs that had been neglected. This isn’t uncommon with performance vehicles as previous owners may defer maintenance to keep costs down, or simply be unaware of the specific needs of a Jaguar XJR.

The anecdote mentions a cracked transmission pan due to overtightening, leading to leaks and necessitating replacement of the pan, filter, gasket, seal, and fluid. This is a critical area to inspect on any used automatic transmission vehicle. Transmission issues can be costly, and preventative maintenance, including regular fluid changes and pan inspections, is paramount for the longevity of the ZF transmission used in the 2004 XJR.

Beyond the transmission, the owner also mentions replacing the radiator and overflow tank, along with coolant, and preemptively changing the mass air flow (MAF) sensor. These are common wear items on cars of this age. The cooling system, in particular, is vital for the supercharged 4.2L V8 engine in the XJR. Overheating can lead to severe engine damage, so regular checks of coolant levels, hose condition, and radiator efficiency are essential. MAF sensors, while sometimes replaced unnecessarily, are crucial for engine management. A faulty MAF can cause poor running conditions, reduced fuel economy, and even trigger fault codes.

For anyone considering a 2004 Jaguar XJR, a thorough pre-purchase inspection by a qualified mechanic specializing in Jaguar vehicles is highly recommended. This inspection should include:

  • Transmission Check: Inspect for leaks, smooth shifting, and consider a transmission fluid analysis.
  • Cooling System Pressure Test: Check for leaks in the radiator, hoses, water pump, and expansion tank.
  • Engine Diagnostics: Scan for fault codes, check engine compression, and assess the condition of belts and hoses.
  • Suspension Inspection: The XJR features air suspension, which, while providing a luxurious ride, can be prone to leaks and failures over time. Inspect air struts and compressor functionality.
  • Brake System Check: High-performance brakes are essential on the XJR. Evaluate brake pad and rotor wear, and check brake fluid condition.

Despite the potential for maintenance, the allure of the 2004 Jaguar XJR is undeniable. The supercharged V8 delivers impressive power and acceleration, while the luxurious interior and refined styling are hallmarks of the Jaguar brand. As one forum user aptly put it, “these cars really are a driving experience that many other manufacturers try to aspire to.”

Owning a 2004 Jaguar XJR is a commitment to maintaining a sophisticated machine. However, for those willing to invest the time and resources into proper upkeep, the rewards are significant. A well-maintained 2004 XJR offers a unique blend of performance, luxury, and classic British automotive heritage, making it a rewarding experience for the discerning driver.
