2.8L V6 Petrol - 150kW (4Motion)
Petrol
Check this by cycling through the gears while stationary; the 4Motion system and automatic transmission should engage smoothly without any hesitation or harsh clunks.
While driving at a steady speed, listen for a 'whine' from the drivetrain, as the centre differential and Haldex unit in these Mk4 models may eventually show signs of age in high-mileage examples.
Test this by turning the steering wheel to full lock in both directions while slowly moving; listen for clicking sounds that could indicate the CV joints might require attention soon.
Check this by inspecting the footwell carpets for any dampness, as the sunroof drains or door seals on the Mk4 platform can sometimes become blocked, leading to moisture ingress over time.
Usually the point where suspension bushings and engine mounts are inspected for signs of wear.
Often considered the interval where cooling system components like the water pump and thermostat housing benefit from a preventative health check.
The time to ensure the Haldex fluid and filter have been refreshed to keep the all-wheel-drive system operating as intended.
Ensure the oil has been changed using high-quality synthetic 5W-40 every 10,000km to keep that V6 running smoothly.
Keep an eye on the coolant colour; these engines prefer G12 or G13 specification coolant to prevent corrosion in the cooling system.
Regularly clean the drain holes under the windscreen cowl to prevent water pooling near the cabin air intake.
Confirm that the spark plugs are replaced at the manufacturer's recommended intervals to maintain the efficiency of the 2.8L engine.
Check the tyre condition and alignment regularly, as the 4Motion setup can be sensitive to uneven rolling diameters.
Estimated repair costs if issues arise
The VR6 engine uses a timing chain rather than a belt. While robust, it is worth keeping in mind that if the guides show signs of wear, the engine may need to be removed for a full overhaul. Future Budget Planning: You might eventually need to budget for this if you notice a rattling sound at start-up.
The 4Motion system relies on a complex pump and control module. If the system stops engaging the rear wheels, it is common to consider professional diagnostics for these electronic components. Future Budget Planning: If this needs attention in the future, the estimated cost in NZ is dependent on parts availability.
Given the age of the Mk4 chassis, the original control arm bushings and shock absorbers may be nearing the end of their service life. Future Budget Planning: Setting aside funds for a suspension refresh will greatly improve the ride quality and handling responsiveness of your V6.
