3.0L Supercharged V6 - Portfolio/Luxury
Petrol
Test drive task: Gently accelerate from a standstill. | Observation: Be mindful of any hesitation in the 8-speed ZF transmission. While these are robust, minor shudders can occasionally occur in higher-mileage examples, which might benefit from a software update or a fluid flush.
Check this by: Cycling through the infotainment touchscreen while stationary. | Observation: These early systems can become sluggish or unresponsive. It is worth confirming that the Bluetooth and navigation modules are functioning as expected for your daily connectivity.
Check this by: Inspecting the air suspension height after the car has been parked overnight. | Observation: Check if the vehicle sits level. A slight 'sinking' on one corner after sitting for days is something to monitor, as it can indicate that the air struts might eventually require attention.
While driving: Listen closely over uneven NZ chip-seal roads. | Observation: Listen for any light knocking from the front end. Control arm bushings are a known wear item on the X351 chassis and are worth keeping an eye on for your long-term comfort.
Consider a full transmission service including fluid and pan filter replacement.
Check the condition of the supercharger coupler and water pump, as these are common service points for the 3.0L V6.
Review the status of the air suspension compressors and lines to ensure long-term reliability.
Prioritise high-quality engine oil changes every 10,000km to keep the supercharged engine running smoothly.
Inspect the panoramic sunroof seals regularly to ensure they stay clear of debris and continue to operate silently.
Check the battery health periodically, as the sophisticated electronics in the XJ are quite sensitive to voltage drops.
Keep the coolant system topped up with the correct specification fluid to protect the longevity of the cooling plastic components.
Ensure the tyre pressures are set precisely to the manufacturer's door placard to maintain the 'Jaguar ride' and prevent uneven wear.
Estimated repair costs if issues arise
In cars of this age, the air bags can eventually lose their seal. Should you notice the car not holding its height, you might eventually need to budget for professional replacement of the struts or the compressor unit.
The plastic cooling pipes around the supercharger can become brittle over time. If a leak appears, it is often wise to replace the surrounding gaskets and hoses to ensure continued performance.
To maintain the refined handling and quiet cabin experience the XJ is famous for, you might eventually need to budget for front suspension bushing replacement if you notice any wandering or light rattling.
