2025 Mercedes-Benz GLB 200 AMG LN Executve Mhev A 1.3L Hybrid electric · GD74 AFJ

As of the assessment date of 2 September 2026, this 2025 Mercedes-Benz GLB 200 AMG Line Executive MHEV Automatic has no recorded MOT test history on the DVSA database. This is entirely expected because the vehicle is only approximately one year old and therefore falls below the statutory MOT testing threshold, which applies to cars once they reach three years of age from the date of first registration. Consequently, there are no recorded pass results, failure items, or advisory notices available to evaluate any trends in mechanical condition, wear progression, or defect recurrence. The absence of MOT data at this stage of the vehicle's life simply reflects its youth rather than any oversight or omission, and no negative inference regarding its maintenance or roadworthiness should be drawn from this blank record. Recorded mileage is not available, and there is insufficient data to compare the vehicle's usage against its age. As a 2025 model, it is reasonable to expect this GLB to have covered between approximately 8,000 and 15,000 miles if used as a daily driver, though corporate, lease, or low-use private ownership could result in substantially lower figures. The 48V mild-hybrid system fitted to this MHEV variant introduces additional electrical components, including a belt-driven starter-generator and a supplementary lithium-ion battery, which operate under different duty cycles to conventional powertrains. Without confirmed mileage, it is prudent to verify the odometer reading against the vehicle's full Mercedes-Benz Digital Service Booklet records to confirm consistency and ensure that the mild-hybrid system has been subjected to regular use, as prolonged periods of standing can degrade the hybrid battery and associated control modules over time. For a prospective buyer evaluating this near-new vehicle, physical inspection should focus on age- and technology-specific concerns rather than conventional wear items. Begin with the tyres: even on a low-mileage 2025 car, check the sidewalls for any signs of cracking, perishing, or UV degradation, and confirm that all four tyres are of matching make, tread depth, and specification, as the GLB's all-wheel-drive readiness and MHEV calibration can be sensitive to rolling circumference differences. Examine the brake discs and calipers closely for any surface corrosion, which can develop rapidly on vehicles that are regularly parked for extended periods, and verify that the caliper slides are free and not binding, as seized calipers are a common issue on lightly used cars. The 12V auxiliary battery and the 48V mild-hybrid battery should both be health-checked, as standing time or short urban journeys can leave both insufficiently charged, leading to premature failure or warning messages. Finally, inspect all exterior panels, the windscreen, and the LED lighting units for any stone chips, condensation, or scuffs consistent with early-life use, and confirm that all warning systems, including the mild-hybrid status display and any driver assistance features, operate correctly. On a test drive, pay particular attention to the smoothness of the automatic transmission, the responsiveness of the mild-hybrid boost function during pull-away, and the absence of any unusual vibrations, clonks, or warning messages from the drivetrain or suspension. Listen for any knocking or rattling from the front suspension, which on low-mileage vehicles can occasionally indicate transit damage or seized components rather than wear. Verify that the start-stop and mild-hybrid systems engage and disengage smoothly, as any harshness may point to software calibration issues or early battery degradation. Finally, confirm the full Mercedes-Benz service history through an authorised dealer or via the manufacturer's online portal, ensuring that all scheduled items, including the specific MHEV system checks and any software updates, have been carried out within the prescribed intervals to preserve both its mechanical integrity and the remaining manufacturer warranty cover.
