3.0L V6 - C280
Petrol
While driving at low speeds, gently turn the steering wheel lock-to-lock to listen for any groans or whines, as the power steering rack in these models can occasionally show signs of age in higher-mileage examples.
Monitoring the temperature gauge during a 15-minute drive; ensure it sits steady in the middle, as aging thermostats or coolant housing seals can lead to slight fluctuations in these V6 engines.
Turn the air conditioning to its coldest setting and verify the airflow pressure remains consistent, as the blend door actuators are known to get a bit stiff or sticky over time.
Look for any minor oil dampness around the rocker cover gaskets, which can become brittle with heat cycles and may eventually require a fresh seal to keep the engine bay tidy.
Typically the time for a thorough suspension bush inspection and potentially a transmission fluid service to keep gear shifts buttery smooth.
An ideal point to confirm the timing chain tensioners are healthy and verify the cooling system components like the water pump have been refreshed.
Consider a full check of the engine mounts, as the natural vibration of the V6 can lead to a slight cabin buzz if the rubber mounts have settled over the years.
Keep up with the engine oil and high-quality filter changes every 10,000km to look after those V6 internal components.
Ensure the transmission fluid service is carried out periodically, as these gearboxes really appreciate fresh oil to maintain precise shifting.
Periodically check the cabin air filter to ensure your climate control system remains efficient and the air remains fresh.
Verify the brake fluid is flushed every two years to maintain that solid, reassuring pedal feel these Mercedes models are famous for.
Keep an eye on the spark plugs according to the service manual, as smooth combustion is key to enjoying the C280's power delivery.
Estimated repair costs if issues arise
In cars of this age, the rubber components can naturally deteriorate from NZ road conditions. If you notice any knocking over bumps, you might eventually need to budget for a refresh of the front-end bushings or control arms.
These gaskets can eventually lose their seal due to heat, leading to minor oil weeping. It is a common maintenance item that ensures your engine stays clean and avoids any burning oil smells.
Depending on the car's history, you might eventually need to budget for a new thermostat and coolant hoses to ensure the V6 runs at its optimal temperature reliably.
