1.2L (HR12DDR) - DIG-S Supercharged performance
Petrol
Accelerate firmly from a standstill and listen for any stuttering or hesitant power delivery, as the supercharger clutch in the DIG-S engine can sometimes show signs of wear.
Cycling through the CVT transmission from Park to Drive and Reverse while stationary; look for any jarring movements or delays that might suggest the belt or pulley system is aging.
Pay attention to the idle quality when you stop at lights; these 3-cylinder engines have a unique character, but excessive vibration could point toward the engine mounts being due for a refresh.
Look for any signs of seepage around the timing chain cover, as high-mileage examples may eventually require resealing to prevent minor oil weeping.
Usually the window to inspect the accessory drive belt and supercharger tensioner assembly for any signs of fatigue.
A common point to consider a transmission fluid flush, even though Nissan may suggest it is a sealed unit, to help maintain the longevity of the CVT.
Recommended interval to check spark plugs specifically designed for the HR12DDR, as their specific heat range is vital for the supercharged performance.
Prioritise regular engine oil changes using high-quality 0W-20 synthetic oil to keep the supercharger internals lubricated and happy.
Keep an eye on the CVT fluid temperature and levels, as this transmission is sensitive to heat and poor maintenance habits.
Ensure the air filter is replaced frequently, as the DIG-S engine relies on efficient airflow to manage its performance mapping.
Test the battery health annually, as the Start-Stop system found in many DIG-S models places extra demand on the electrical system.
Monitor tyre pressure regularly, as the Note’s suspension geometry performs best when all four corners are perfectly balanced.
Estimated repair costs if issues arise
Future Budget Planning: While the CVT is generally reliable if driven gently, you might eventually need to budget for a professional fluid exchange to ensure smooth operation as the vehicle reaches higher kilometres.
Future Budget Planning: The DIG-S system is clever, but if this component needs attention in the future, the estimated cost in NZ reflects the specialized labor required to access the supercharger unit.
Future Budget Planning: Depending on the car's history and the condition of our local roads, you might eventually need to budget for fresh engine mounts to restore the cabin's smooth, quiet feel.
