6.0L W12 Twin-Turbo (412kW)
Petrol
Test drive task: Perform a slow-speed full-lock turn. | Description: Check this by listening for any groaning or clunking from the suspension. In cars of this age, it's common to consider that the complex front control arms and air suspension bushings may be showing their miles.
Test drive task: Gently accelerate through the lower gears. | Description: Observe the gear shifts for any hesitations. The ZF 6-speed automatic is robust, but you'll want to ensure the transitions feel smooth and consistent.
Test drive task: Activate all climate control zones. | Description: Check this by confirming both passenger and driver sides reach the desired temperatures. It is worth noting that the HVAC blend door actuators can occasionally become temperamental in these luxury cabins.
Test drive task: Idle the engine for several minutes upon returning. | Description: Check this by monitoring the temperature gauge and looking for any signs of coolant leaks under the chassis. The W12 engine produces significant heat, making the cooling system's health vital.
Usually involves a deep check of the air suspension system and potential replacement of front end bushings.
Often the time to inspect the turbocharger coolant lines and vacuum hoses which can become brittle over time.
Typically recommended for a full transmission fluid service and inspection of the secondary ignition components.
Verify that the hydraulic fluid for the suspension is at the correct level and clear in appearance.
Ensure all electrical features, particularly seat adjustments and mirror folding, operate smoothly.
Check the service history for regular oil changes, ideally using high-quality synthetic oil to keep the W12 running optimally.
Inspect the tyres for even wear patterns, which indicates that the sophisticated alignment is in good health.
Confirm that the battery charging system is healthy, as these cars have many computers that prefer a strong, stable voltage.
Estimated repair costs if issues arise
If these struts or the compressor eventually need attention, you might want to factor in the cost of high-quality components and the specialized labour required for this setup.
Depending on the car's history, you might eventually need to budget for refreshing the lines surrounding the W12's twin turbos to prevent leaks.
Accessing all 12 cylinders is a labour-intensive task. If this component needs attention in the future, the estimated cost in NZ reflects the time required to reach the engine components deep within the bay.
