2.0L (OM654) - E220d Latest Generation Diesel
Diesel
During the first 10 minutes of driving, pay close attention to the gear shifts. If you notice any hesitation or clunky changes, it is worth asking about the transmission service history, as these 9G-TRONIC units benefit from regular oil changes.
Before turning the engine on, sit in the driver's seat and listen for any rattles from the dashboard or trim. While these cars are premium, plastic clips can occasionally loosen over time on NZ roads, so it is good to identify any annoying buzzes early.
Check the AdBlue system by asking the owner if they have received any recent warnings. The OM654 engines are efficient, but the sensors in the AdBlue tank can occasionally trigger a dashboard warning light; check if the tank has been topped up recently.
Inspect the infotainment screen and touchpad during your test drive. Use them extensively to ensure the COMAND or MBUX system responds quickly, as the electronics are sophisticated and you want to ensure there is no lag or ghost touching.
Usually marks the first major service interval where transmission fluid and differential oils are often recommended for replacement.
Considered a point where suspension components, such as air suspension bellows if fitted, should be inspected for signs of wear or slow leaks.
Often the time when the diesel particulate filter (DPF) regeneration cycles should be monitored to ensure they are completing successfully.
Ensure the oil has been changed strictly according to the schedule using the correct MB-approval 229.51 or 229.71 spec oil.
Check the service history for evidence of brake fluid flushes every two years to keep the safety systems performing at their best.
Verify the coolant has been replaced periodically to protect the sophisticated aluminium engine components.
Inspect the tyres for uneven wear, as wheel alignment is sensitive on these models and vital for tyre longevity on our chip-seal roads.
Keep an eye on the cabin air filter condition to ensure the climate control system remains fresh and free of debris.
Estimated repair costs if issues arise
If the AdBlue sensors or pump require attention, it's worth knowing that these are integrated systems. Depending on the car's history, you might eventually need to budget for a sensor recalibration or tank unit replacement to keep the emissions system compliant.
If your specific W213 is equipped with AIRMATIC suspension, it's common to consider that these components eventually experience natural wear. If a strut begins to lose pressure, it is usually replaced in pairs to ensure ride comfort remains as intended.
While the 9G-TRONIC is a smooth performer, keeping it that way relies on fresh fluid. If this component needs attention or a major scheduled service in the future, the estimated cost in NZ involves specific ATF fluid and filter kits.
