3.0L AJ-V6 - Executive
Petrol
Gently navigate a bumpy road while listening for clunks from the suspension; the X350's air suspension system is clever, but in cars of this age, it's common to consider that air struts may eventually show their years.
Use the electronic parking brake repeatedly while stopped on an incline, as these actuators can become sluggish if they haven't been used regularly throughout the vehicle's life.
Check the transmission shifting by accelerating gently through the gears; if you feel any hesitation or 'hunting' between gears, it is worth investigating if the sealed-for-life transmission fluid is due for a service.
Observe the dashboard for any flickering or warning lights immediately upon cold start, as the complex electrical architecture can sometimes be sensitive to battery voltage fluctuations.
Usually the time to evaluate the health of the air compressor and control arm bushings.
A sensible interval to ensure the cooling system components, such as hoses and the header tank, have been refreshed.
Consider a full check of the timing chain tensioners and secondary drive belts to maintain smooth engine operation.
Ensure the engine oil and filter have been changed at least every 10,000km to keep the 3.0L V6 running sweetly.
Inspect the underside for any signs of corrosion, which is always good practice for imported luxury vehicles in our coastal climate.
Verify that the battery is in peak condition, as these Jaguars rely on a strong charge to keep the various ECUs communicating correctly.
Check that all interior electrical features, including the infotainment and climate controls, are functioning through their full range of motion.
Keep a consistent eye on coolant levels and inspect the cooling system plastic housings for any signs of aging or brittle seals.
Estimated repair costs if issues arise
If this component needs attention in the future, the estimated cost in NZ is reflective of replacing complex individual struts or the pump assembly to restore that signature wafting ride.
Depending on the car's history, you might eventually need to budget for a transmission fluid and filter change, which helps maintain the smoothness of the ZF automatic gearbox.
It is common to consider that the rubber bushings in the aluminium suspension may wear over time, which involves replacing the control arms to tighten up the handling.
