Diesel
Listen for timing chain rattle during a cold start. | Description: While the OM651 engine is generally robust, it is worth monitoring the timing chain for any metallic rattling sounds during the first few seconds of a cold engine start, as this can indicate wear on the chain tensioner.
Check for smooth transitions while moving between reverse and drive. | Description: Test the 7G-DCT dual-clutch transmission by performing low-speed maneuvers. You want to ensure the gear changes feel fluid rather than jerky, as these transmissions prefer smooth throttle inputs.
Inspect the front lower control arm bushes for any clunking noises over bumps. | Description: Find a quiet side street with some speed humps or uneven surfaces to listen for any suspension knocks, which may suggest the bushings have reached the end of their service life given local road conditions.
Verify the operation of the infotainment screen while stationary. | Description: Check that the Command/Audio 20 system boots up cleanly and the display remains flicker-free, as aging electronics can occasionally develop connection issues in the wiring loom.
Consider a proactive transmission fluid and filter service to ensure the DCT continues to shift smoothly.
The diesel particulate filter (DPF) may benefit from a professional diagnostic check to ensure successful regeneration cycles.
A good time to inspect the auxiliary drive belt and tensioner assembly as part of your ongoing care routine.
Stick to the manufacturer's recommended oil change intervals using high-quality synthetic oil to protect the turbocharger.
Ensure the AdBlue system is filled with fresh fluid periodically to avoid any dashboard warning lights.
Keep the panoramic sunroof tracks (if fitted) clean and lubricated to prevent sticking or motor strain.
Regularly inspect tyre wear patterns, as these vehicles can be sensitive to wheel alignment settings.
Ensure the coolant is flushed at the recommended intervals to prevent corrosion within the cooling system.
Estimated repair costs if issues arise
Regular maintenance of the dual-clutch unit is key to its longevity. If you find the shifting becomes less refined in the future, it is worth budgeting for a full fluid and filter service to keep everything operating as designed.
New Zealand's varied road surfaces can accelerate the wear of rubber suspension components. Depending on the car's history, you might eventually need to budget for replacing the front control arm bushings if you notice any wandering steering or unwanted noises.
If the vehicle is primarily used for short city trips, the diesel particulate filter may struggle to regenerate. If this light appears, a professional chemical clean is often a helpful maintenance step to avoid a full component replacement.
