Check the EP6 engine response by idling for several minutes. | Observation: In cars of this age, notice if the engine runs unevenly or if the check engine light flickers; this can sometimes indicate carbon buildup on the intake valves, which is a known characteristic of these direct-injection units.
Operate the electric windows and folding mirrors repeatedly. | Observation: It is worth checking that these functions operate smoothly, as the wiring looms in the door hinges can occasionally become brittle, leading to intermittent electronic connectivity issues.
Test the manual gearbox through every gear, including reverse. | Observation: Observe if the shift feels heavy or 'notchy', as the clutch slave cylinders or gearbox linkage bushings may be reaching the stage where they benefit from some maintenance or lubrication.
Listen carefully to the suspension while driving over uneven road surfaces or speed bumps. | Observation: Listen for any light knocking sounds; the front sway bar links and control arm bushes are common wear items on New Zealand roads that might eventually require attention to maintain a smooth ride.
Usually the time to inspect the cooling system integrity and ensure no signs of weeping from the water pump.
Recommended to have the accessory belt and tensioner pulleys inspected, as these rubber components can show age-related wear.
Consider a thorough inspection of the suspension strut mounts and any chassis-related bushes to keep the car handling as it did when new.
Check the engine oil level every few weeks, as these engines appreciate being kept topped up with the correct synthetic grade.
Ensure the cabin air filter is replaced annually to keep the unique DS interior feeling fresh and the air conditioning working efficiently.
Verify that the coolant is clean and the expansion tank shows no signs of residue, which helps protect the engine's long-term health.
Keep an eye on the tyre tread depth and alignment, as the DS4's geometry benefits from being balanced to ensure even wear.
Regularly clean the door seals with a silicone-based treatment to prevent them from drying out or sticking in colder NZ temperatures.
Estimated repair costs if issues arise
If the engine idle becomes slightly rough or loses power, you might eventually need to budget for a professional induction cleaning process to remove carbon deposits from the valves.
Depending on the car's history, you might eventually need to budget for replacing the front lower control arm bushes if you notice excessive vibration or steering feedback.
If this component needs attention in the future, the estimated cost in NZ is reflective of the labour involved in accessing the gearbox assembly.
