5.0L Supercharged AJ133 V8 - Modern Era Performance Flagship
Petrol
Check this by observing the transmission during light acceleration. | Note: While driving, ensure the ZF 8-speed shifts are crisp; in cars of this age, it is common to consider that a gearbox fluid service may be due to maintain smoothness.
While parked, listen closely to the engine bay during a cold start. | Note: Listen for any rhythmic ticking; it is worth being aware that the timing chain tensioners on the AJ133 engine have been a point of discussion for long-term ownership.
Check this by cycling through all infotainment menus and seat adjustments. | Note: The X351 interior is feature-rich, so spend time ensuring all electronic modules respond; simple resets are sometimes needed, but it is wise to ensure there is no evidence of moisture ingress.
During the drive, navigate over a few uneven road surfaces. | Note: The air suspension provides a sublime ride, but it is reasonable to expect that components like the compressor or struts may eventually require maintenance as the vehicle ages.
Usually the time to inspect coolant crossover pipes, which can become brittle over time.
A sensible interval to assess the health of the supercharger coupler and auxiliary drive belts.
Consider a full service of the differential fluid and a proactive check of the suspension bushings.
Prioritize oil changes every 8,000 to 10,000km to keep that supercharged V8 performing at its best.
Keep an eye on coolant levels, as the cooling systems in these engines benefit from regular inspections of the plastic housing components.
Ensure the battery is always healthy, as modern Jaguar electronics are quite sensitive to low voltage.
Regularly clean the drainage points around the sunroof and scuttle area to protect the cabin electrics.
Keep a consistent service history, as high-performance Jags thrive when maintained by specialists who understand the AJ133 platform.
Estimated repair costs if issues arise
Because many cooling components are made of high-grade plastic, it is good practice to budget for a preventative refresh of these parts to avoid future overheating.
While the ride is world-class, the air suspension is a wear item. Depending on the car's history, you might eventually need to budget for a replacement strut or pump.
If this component needs attention in the future to ensure the longevity of your engine, the estimated cost reflects the labor-intensive nature of accessing the front of the V8.
