Check the MBUX infotainment transition while idling. | Note: While driving, ensure the dual-screen interface remains responsive. In some W247 models, intermittent screen freezing can occur, which might require a software update or a control module reset.
Listen carefully during low-speed gear shifts. | Note: While driving in stop-start traffic, pay attention to the 8-speed DCT gearbox. It’s common in vehicles of this age to notice minor hesitation; however, if you feel significant shuddering, it's worth having the transmission fluid levels and software calibration inspected.
Test the stop-start function at a standstill. | Note: Check this by coming to a complete stop and allowing the OM654 engine to cut out. If the restart feels exceptionally sluggish, it is worth monitoring the condition of the secondary auxiliary battery, as these often age alongside the main battery.
Inspect the door and boot seals after a wash or rain. | Note: Check this by running your hand along the interior door sills. On some B-Class examples, minor seal compression can lead to dampness, which is something to keep an eye on to ensure the interior cabin remains in top condition.
Consider a transmission fluid flush to maintain the longevity of the dual-clutch system.
Check the condition of the DPF (Diesel Particulate Filter) sensors and ensure the AdBlue system is operating within optimal parameters.

Have the brake fluid flushed every two years to ensure the safety systems remain responsive in wet conditions.
Estimated repair costs if issues arise
If this component needs attention in the future, it is wise to budget for a professional fluid and filter exchange to keep the gear changes crisp and reliable.
Depending on the car's history, you might eventually need to budget for a sensor or heater element replacement, as these are exposed to chemical buildup over time.
If the vehicle encounters rough road conditions frequently, it is common to consider replacing front control arm bushings or dampers to maintain that signature Mercedes ride quality.
