4.2L (AJ-V8) - Luxury/SE trim
Petrol
Gently accelerate from a standstill and listen for any hesitation; the ZF 6-speed transmission is generally robust, but check for smooth, non-jerky shifting between 2nd and 3rd gears.
Turn the steering wheel fully to both locks while idling to listen for whining noises, which may indicate the power steering pump or the fluid level requires attention.
Opening the bonnet while the engine is running to ensure there are no rhythmic ticking noises from the top of the engine, which helps rule out potential variable valve timing (VVT) solenoid wear.
Operating all electrical seat adjustments and window switches, as the S-Type's complex wiring loom can occasionally show age-related gremlins in the switchgear.
Usually the time to ensure the transmission fluid has been serviced, as clean fluid is key to longevity for the ZF unit.
Consider having the suspension bushings and ball joints inspected, as NZ roads can accelerate wear on these components.
A sensible interval to confirm the health of the cooling system components like the water pump and thermostat housing.
Keep a consistent eye on engine oil levels, as the AJ-V8 prefers to be kept topped up with high-quality synthetic oil.
Ensure the cooling system is flushed on schedule, as heat is the biggest challenge for an engine of this sophistication.
Regularly clear out the cabin air intake and scuttle panel drains to prevent moisture buildup in the footwells.
Check the condition of the serpentine belt every service to avoid the inconvenience of an unexpected roadside snap.
Maintain the battery health; these cars have many electronic modules that prefer a strong, stable voltage.
Estimated repair costs if issues arise
Given the age of these vehicles, the rubber bushings and control arms may eventually soften. If the steering starts to feel a bit loose or you hear clonks over bumps, you might eventually need to budget for a suspension refresh to restore that signature Jaguar ride quality.
In cars of this age, plastic cooling components like the thermostat housing can become brittle. To avoid future overheating, it is worth keeping a buffer for a cooling system overhaul if you notice any minor coolant scent or droplets.
While the transmission is a highlight, keeping the fluid fresh is vital. If this hasn't been done recently, you may wish to budget for a transmission oil and pan-filter change to ensure smooth operation for years to come.
