4.5L V8 - Naturally aspirated luxury SUV
Petrol
Check this by inspecting the coolant reservoir and under the engine bay; look for signs of coolant leaks as the plastic 'coolant pipes' in these V8 engines can become brittle with age and heat cycles.
While driving at low speeds, listen carefully for any clunking or knocking from the front end, which may indicate that the control arm bushings or air suspension components are nearing the end of their current lifecycle.
Test this by cycling through every setting on the air suspension, ensuring the compressor rises and lowers the vehicle smoothly without warning lights appearing on the dashboard.
Inspect the service history for recent transmission fluid changes, as these Tiptronic units benefit greatly from proactive servicing to maintain smooth gear changes as the kilometres climb.
Usually marks the point where suspension bushings and engine mounts begin to show signs of wear.
A common window where the cooling system components and water pump might require preventative attention.
Often the time to assess the condition of the driveshaft center support bearing and exhaust system integrity.
Stick to a strict oil change interval of every 10,000km or annually to keep that V8 running as smooth as a Kiwi summer day.
Keep a close eye on your coolant levels and top up only with the manufacturer-recommended fluids to protect the engine internals.
Ensure the cabin filters are replaced regularly, as these help keep the complex climate control systems functioning without strain.
Prioritise high-quality tyres, as the heavy weight of the Cayenne S makes them vital for both handling and effective braking performance.
Keep the sunroof drains clear of debris to prevent any moisture buildup inside the cabin, which is a simple task that saves a lot of headaches.
Estimated repair costs if issues arise
If the original plastic pipes are still installed, you might eventually need to budget for an upgrade to metal piping. This is a comprehensive job that involves accessing the top of the engine, so it is a good project to combine with other intake-related maintenance.
Depending on the car's history, the air suspension compressor may eventually need refurbishment or replacement. If the car seems to 'sit' unevenly or struggles to lift, it is common to consider this a future priority.
If you notice a vibration through the floor during acceleration, it is common to consider the cardan shaft support bearing. Replacing the rubber carrier is a standard maintenance task for high-mileage examples.
