2.0L (OM654) Turbo Diesel - V220 d
Diesel
Cycle through all gears in the 9G-TRONIC transmission. Pay attention to any hesitance or lurching when shifting between first and second, as the valve body can sometimes display sensitivity in these heavy chassis.
Operate the electric sliding doors repeatedly while the vehicle is parked on an incline. Listen for any strained motor sounds or 'rebound' issues, which can indicate the anti-pinch sensors or door actuators may require calibration.
Test the AirMATIC suspension by toggling the vehicle height adjustment. Listen carefully for any rhythmic clicking or prolonged compressor noise, as air struts and the compressor are known to eventually show signs of wear given the vehicle's weight.
Check the infotainment trackpad and screen responsiveness thoroughly. These interface components are integrated into the wider cabin electronics and can occasionally experience glitches that benefit from a software refresh.
Usually marks the first major service interval, checking transmission fluid health and cabin filtration systems.
A common point where secondary cooling components and suspension bushes may begin to show natural aging symptoms.
Typically the time to verify the health of the diesel particulate filter (DPF) and the secondary AdBlue delivery components.
Prioritise an official Mercedes-Benz digital service history to ensure the OM654 engine has received the correct low-ash oil specification.
Check that the AdBlue tank has been topped up correctly, as these systems rely on precise fluid quality to avoid sensor errors.
Inspect the tyre condition across all four corners, as the V-Class weight distribution can lead to uneven wear if alignment is neglected.
Verify that any software recalls or dealer updates have been applied, particularly those relating to emissions control modules.
Keep the sunroof rails and door runners lubricated regularly to prevent long-term friction wear on the motors.
Estimated repair costs if issues arise
As these bags hold the weight of a large vehicle, it is common to consider that they may lose efficiency over time. If the car sits unevenly when parked, it is worth setting aside funds for replacement struts.
Modern diesel emissions systems are sophisticated. Depending on the car's driving cycle, you might eventually need to budget for sensor replacements if the engine warning light indicates an exhaust treatment fault.
This is a highly reliable gearbox, but it requires fresh fluid to stay that way. It's smart to plan for this service every 60,000-80,000km to ensure the longevity of the mechatronic unit.
