4.8L V8 Twin-Turbo - Turbo
Petrol
While driving at low speeds, gently turn the steering wheel to full lock to listen for any knocking sounds from the suspension, as worn control arm bushings are common in these heavy SUVs.
Check this by shifting the transmission from Park to Drive and Reverse while stationary to feel for any sharp jerks or hesitation, which could indicate wear in the valve body of the Tiptronic gearbox.
While accelerating moderately on an open road, observe the engine temperature gauge and listen for any unusual ticking or tapping from the engine bay, as cooling system plastic components can become brittle over time.
Before your drive, manually cycle the air suspension through all its height settings to ensure the compressor engages quietly and the vehicle levels itself without any dashboard warning lights.
Usually marks the window where cooling pipes and expansion tanks may show signs of heat fatigue.
Typically the point where original ignition coils and spark plugs are due for their second refresh to maintain smooth V8 performance.
Often the time to inspect the cardan shaft center support bearing for signs of vibration or rubber perishing.
Verify the coolant pipes have been upgraded to the metal variants if the vehicle still sports the original plastic versions.
Ensure the transmission fluid and filter have been serviced, as clean fluid is vital for the longevity of these complex gearboxes.
Check the service history for regular oil changes, ideally every 10,000km, to keep those twin turbochargers well-lubricated.
Inspect the condition of the brake discs and pads, as the Turbo model's stopping power is impressive but comes at the cost of faster wear.
Look for a fresh warrant of fitness and ensure all electrical features, like seat adjustments and infotainment, have been tested recently.
Estimated repair costs if issues arise
If this component needs attention in the future, the estimated cost in NZ is reflective of the complex nature of the system. It helps to keep a small buffer in case the compressor or a strut seal requires replacement.
Depending on the car's history, you might eventually need to budget for a repair to the center support bearing, which can manifest as a slight vibration under the center console.
In cars of this age, it's common to consider a proactive cooling system overhaul, including the water pump and expansion tank, to ensure reliable performance on long Kiwi road trips.
