1.7L (M166) - A170 CDI Diesel
Diesel
When accelerating from a standstill, monitor the dashboard for any 'glow plug' or 'check engine' warning lights. | Description: On the A170 CDI, the glow plug relay or individual plugs can show their age; this might indicate they require replacement to ensure smooth cold starts in cooler New Zealand mornings.
While maneuvering at low speeds, observe the steering effort and listen for any 'whine' or inconsistent feedback. | Description: The power steering pump on the W168 is electric-hydraulic, and occasionally the pump unit may become noisy as it nears the end of its service life.
Check this by shifting through all gears while stationary, then again on a short drive, specifically noting any hesitation or 'clunking' in the gearbox. | Description: Whether you are looking at the 5-speed manual or the automatic, the linkage or fluid condition is worth verifying, as smooth gear selection is key to the longevity of these transmissions.
Once the engine is warm, pop the bonnet and observe the engine bay for any signs of weeping around the injectors. | Description: Commonly known as 'black death' in diesel circles, injector seal leaks can occur over high mileage; noticing this early allows for a straightforward repair rather than a complex one.
Consider a full cooling system flush and inspection of all rubber coolant hoses.
It is a good time to look at the health of the suspension bushings and steering tie-rod ends for any perishing.
Monitor the alternator and starter motor performance, as these components have likely worked hard over this distance.
Prioritize high-quality synthetic engine oil changes every 10,000km to protect the turbocharger.
Keep a close eye on the condition of the serpentine belt, as it drives multiple essential accessories.
Regularly clean out the plenum chamber area beneath the windscreen to prevent water ingress into the cabin electronics.
Check the brake fluid moisture levels every two years to ensure the braking system remains responsive.
Periodically inspect the exhaust system for any surface corrosion, which is more common in coastal NZ regions.
Estimated repair costs if issues arise
Given the age of these vehicles, the turbocharger may eventually show signs of wear. If you notice a loss of power or excessive oil consumption, it is wise to have the unit inspected or refurbished.
If you notice a vibration or difficulty shifting under load, you might eventually need to budget for a clutch replacement. It is often best to address this alongside the flywheel if it has reached its service limit.
New Zealand roads can be demanding on suspension components. If the car feels 'loose' or knocks over bumps, planning for a set of new control arms or shock absorbers will significantly improve your driving experience.
