4.2L Supercharged V8 (AJ34S) - XKR Performance
Petrol
Test Drive Task: Monitor the gear shifts while accelerating moderately from a standstill. | Detail: On these 6-speed ZF automatic transmissions, it is common to consider whether shifts are smooth or if there is any hesitation, as the mechatronics units can occasionally show signs of wear as they age.
Test Drive Task: Listen carefully at idle with the bonnet open. | Detail: Check this by ensuring the supercharger pulley and tensioner assembly are quiet; while these engines are robust, components like the supercharger snout can develop a subtle rattling sound over time which is worth noting.
Test Drive Task: Perform a 'lock-to-lock' steering check while stationary. | Detail: In cars of this age, it is wise to observe if there is any whining from the power steering pump or groaning from the suspension bushings, as these alloy-heavy front ends appreciate fresh bushes periodically.
Test Drive Task: Operate every electronic feature inside the cabin. | Detail: Spend a few minutes testing the touch-screen, seat heaters, and infotainment system, as the complex electrical architecture can sometimes present minor quirks if a battery has been sitting low in voltage.
Usually the time to inspect suspension geometry and steering rack integrity.
Consider a full service of the transmission fluid and filter to ensure long-term smooth operation.
Check all engine cooling hoses and the water pump for signs of age-related degradation.
Prioritize high-quality synthetic engine oil changes every 10,000km to keep that V8 supercharger internals happy.
Regularly check the battery health, as these Jaguars are very sensitive to voltage drops which can trigger false warning lights.
Keep an eye on the coolant expansion tank for any fine hairline cracks, which is a common item to address as plastics age.
Ensure the air conditioning system is used regularly to keep seals lubricated and the system functioning optimally.
Check tyre pressure and condition frequently, as the XKR’s performance nature can be quite demanding on the inner edges of the rubber.
Estimated repair costs if issues arise
If this component needs attention in the future, the estimated cost in NZ is reflective of the specialized labour required to remove and service the supercharger unit.
Depending on the car's history, you might eventually need to budget for a refresh of the front control arm bushings to maintain that signature 'Jaguar' ride quality.
If the transmission begins to show minor shifting irregularities, a service kit and fluid change is a sensible step to help preserve the long-term health of the gearbox.
