While accelerating gently from a stop, pay attention to the 48V EQ Boost system; any hesitation or jitteriness might suggest a need for a software update or calibration check.
Park the car and toggle through the MBUX infotainment menus, ensuring the touch surfaces and voice recognition respond promptly, as complex electronics can occasionally require a reset.
Engage the air suspension (if equipped) and toggle between comfort and sport modes while stationary; listen for any abnormal compressor noise or delayed leveling times.
Check the panoramic sunroof operation by cycling it fully open and closed, ensuring there are no signs of track sticking or unusual wind noise at highway speeds.
Consider a major service including spark plug replacement and fresh transmission fluid for the 9G-TRONIC gearbox.
Keep an eye on the condition of the auxiliary battery for the mild-hybrid system, which may start showing signs of fatigue.
Recommend a comprehensive inspection of the suspension bushings and air bellows, as these components have seen significant road usage.
Ensure the logbook shows regular servicing intervals, ideally at an authorized Mercedes-Benz service centre or a reputable European specialist.
Confirm the cooling system is maintained, as the M256 engine relies on precise thermal management to stay efficient.
Check the tyre tread depth across the whole width; these vehicles are known to be sensitive to alignment, which keeps road noise low.
Verify that the 12V and 48V battery systems have been tested during recent routine inspections.
Keep the cabin filter fresh to ensure the advanced climate control system performs at its best.
Estimated repair costs if issues arise
If the vehicle sits lower than usual after being parked for a few days, you might eventually need to budget for airbag strut replacement or compressor servicing.
As part of your future budget planning, keep in mind that the mild-hybrid lithium-ion battery is a complex component that may reach the end of its intended lifecycle after several years of operation.
Due to the vehicle's substantial weight, brake consumables are normal wear items. Depending on your driving style, setting aside a rainy day fund is wise for when the sensors indicate a change is due.
