Petrol
While at a complete stop in Drive with your foot on the brake, observe if you feel a harsh vibration or shutter through the floor. | Note: The M274 engine's motor mounts can wear out, causing noticeable cabin vibration. It's common to consider this a wear-and-tear item once the vehicle exceeds 80,000km.
Check this by performing a low-speed maneuver into a tight parking spot while listening closely to the suspension. | Note: Some owners have noted the front-end suspension bushings can start to show their age, potentially leading to minor clunks or knocks over uneven NZ road surfaces.
While driving, monitor the infotainment screen and instrument cluster for any flickering or software lag. | Note: As these cars feature complex digital displays, occasional software glitches can occur. It's worth verifying that the system is updated to the latest available Mercedes firmware.
Check this by accelerating moderately from a low speed and listening for any high-pitched whirring or unusual intake noises. | Note: It is worth checking the service history for water pump or coolant housing inspections, as these are components that can occasionally require attention as the vehicle ages.
Time to inspect suspension bushings and motor mounts.
Primary service milestone for spark plugs and major fluid flushes.
Consider a proactive check of cooling system components and serpentine belt condition.
Verify the transmission fluid has been changed according to the Mercedes-specified intervals.
Check for a consistent record of oil changes, ideally every 10,000-15,000km, to keep the turbocharger healthy.
Ensure all recall campaigns regarding airbags or software have been completed by an authorized dealer.
Inspect the cabin air filter and climate control efficiency for fresh, odour-free airflow.
Confirm the brake rotors and pads are within specification, as these are heavier vehicles that use consumables steadily.
Estimated repair costs if issues arise
If you notice increased vibration during your ownership, you might eventually need to budget for new mounts to restore that signature Mercedes smoothness.
Depending on the road conditions the car has faced, you may want to keep some savings aside for eventual front-end suspension work to maintain comfortable handling.
If this component needs attention in the future, addressing it proactively can prevent overheating, which is a sensible approach for any European luxury car.
