Petrol
While at a standstill in neutral, listen for any rattle or whine from the supercharger | Detail: These M112 Kompressor units are robust, but it is wise to ensure the internal bearings aren't showing signs of fatigue from age.
Check this by accelerating firmly on an open road to feel for smooth power delivery | Detail: If the car hesitates or enters limp mode, it is worth investigating the Intercooler pump, as these can occasionally underperform on higher-mileage examples.
Inspect the dashboard console while driving to ensure the fixed rear spoiler deploys and retracts | Detail: The spoiler hydraulic or electrical system can occasionally become sluggish in older models, so it is a good idea to verify the movement is consistent.
While steering at low speeds, pay close attention to any clunking noises from the front end | Detail: The suspension components, such as control arms and bushings, are quite hardworking; checking for any uneven tyre wear is a great way to gauge their condition.
Usually the time to inspect the condition of the supercharger belt and accessory tensioners.
Consider having the transmission fluid inspected, as the 5-speed automatic benefits from fresh fluid to maintain smooth shifts.
A sensible interval to assess the health of the engine and transmission mounts, which can harden over time.
Prioritise regular oil changes using high-quality synthetic oil to keep that supercharger and V6 internals happy.
Keep an eye on the coolant levels; ensuring the cooling system is free of debris helps keep engine temperatures stable.
Check the condition of your air filters, as they are crucial for keeping the supercharger intake breathing freely.
Perform a quick visual check of the under-carriage to ensure all plastic undertrays are secure.
Regularly treat the rubber seals around the windows and doors to keep them supple and prevent wind noise.
Estimated repair costs if issues arise
If you notice a slight power drop after sustained driving, this pump may be nearing the end of its service life. It is a known component that often requires a refresh on older performance M112 engines.
To keep the handling sharp and true, you might eventually need to budget for a refresh of the front control arm bushings. This ensures the car remains planted and predictable on winding NZ roads.
If the gear shifts feel less crisp than expected, a full transmission service including the filter and fluid can be a great investment for the car's longevity.
