2024 Mercedes-Benz EQB 250+ AMG Line Executive Electric · BL74 UNH

The defining mechanical narrative for this 2024 Mercedes‑Benz EQB 250+ AMG Line Executive is the complete absence of any recorded MOT examinations, meaning there is no documented evidence of roadworthiness, nor any indication of recurring advisories or failures that could inform a trend. Without a single test entry, the vehicle’s compliance with the statutory safety and emissions standards remains unverified, placing the prospective buyer in a position where the baseline condition must be established through independent inspection rather than historical MOT data. Mileage information is likewise unavailable, preventing any assessment of annual kilometre accumulation or identification of periods of unusually high use that could accelerate wear on drivetrain, suspension or battery components. For a four‑year‑old EV, a typical annual mileage would be in the region of 8‑12 000 mi; the lack of recorded figures means the buyer cannot gauge whether the battery has been subjected to intensive fast‑charging cycles or whether the vehicle has been predominantly urban or motorway based, each of which bears distinct mechanical implications. A thorough pre‑purchase inspection should therefore concentrate on the high‑voltage system and its ancillary components. Verify the state of health of the lithium‑ion pack through a diagnostic read‑out of capacity, cell balance and coolant temperature, and confirm that the charging port and on‑board charger show no signs of corrosion or loose connections. Examine the electric motor and inverter for abnormal acoustic signatures or excessive vibration, and ensure that the regenerative‑braking function integrates smoothly with the hydraulic brake system, with pads and discs measured for remaining thickness and even wear. Inspect the suspension – control‑arm bushes, coil springs and anti‑roll bars – for any play, cracking or corrosion, and check the steering rack and tie‑rod ends for binding or excessive free play. Finally, assess the bodywork for hidden rust, particularly around wheel arches, under‑body panels and the battery enclosure, and confirm that all lighting, wipers and electronic driver‑assist features operate without fault. During a test drive, listen for any high‑pitched whine or grinding from the motor at low and high speeds, and note any pulsation through the steering column that could indicate motor or suspension issues. Observe the vehicle’s acceleration for smoothness and consistency of range, watching for sudden drops in displayed remaining charge that may signal battery degradation. Apply the brakes firmly to feel for pedal firmness, any judder, or a pull to one side, and verify that the regenerative‑braking transition is seamless. Watch for warning lights on the instrument cluster, and confirm that the charging port latch engages securely and that the vehicle can be plugged in without difficulty. These observations, combined with a full diagnostic scan, will provide the concrete evidence needed to judge the EQB’s roadworthiness in the absence of MOT history.
