2.0L (GW4D20) Turbo Diesel - Premium/Luxury
Diesel
Test drive task: Perform a cold start and listen for any sluggish cranking or unusual clicking sounds from the engine bay. | Note: In older diesel models, the starter motor and battery health can gradually decline; it is wise to ensure the vehicle starts promptly every time.
Check this by: Accelerating briskly on an open road to listen for any lag or unusual whistling noises from the turbocharger area. | Note: Diesel turbos have a long service life, but in cars of this age, it is common to consider checking the intake hoses for potential leaks or perishing.
While driving: Pay attention to the gear changes if you are viewing an automatic model, ensuring shifts are smooth without any hesitation or flaring. | Note: Automatic transmissions benefit from fresh fluid, so it is worthwhile to check if the previous owner has kept up with transmission servicing.
Check this by: Cycling through all infotainment and interior climate controls while the car is idling to ensure no electronic glitches appear. | Note: Sensor or screen sensitivity can sometimes be a quirk of vehicles reaching this age, so testing every button is a great way to verify everything is in working order.
Usually a great time to check the condition of all drive belts and ensure the cooling system is flushed to maintain efficiency.
Consider having a professional inspect the suspension components, such as control arm bushings, which naturally experience wear over time.
A major milestone where checking the turbo health and giving the fuel system a thorough inspection is recommended for continued reliability.
Keep to a strict engine oil and filter change schedule every 10,000km to protect the turbocharger.
Regularly inspect your coolant levels, as maintaining a clean cooling system is vital for engine longevity in our NZ climate.
Ensure the DPF (Diesel Particulate Filter) gets a chance to regenerate by taking it for a longer highway drive occasionally.
Check your brake fluid and pads periodically, as keeping these fresh makes for a much more confident driving experience.
Keep a record of your service history, as a well-documented logbook is a great asset for the future value of your H6.
Estimated repair costs if issues arise
If you mostly do short city trips, the DPF can accumulate soot. If it requires a professional forced regeneration or a deeper clean later, it is wise to have a buffer.
New Zealand roads can be tough on suspension components. Depending on the car's history, you might eventually need to budget for replacing worn bushings to keep the ride feeling fresh.
While the turbo is robust, should it require refurbishment or replacement down the line, it is a significant component to account for in your future budget planning.
