2022 Mercedes-Benz GLB 200 AMG Line Premium + A 1.3L Petrol · WF72 MBX

A single DVSA test pass from October 2025 with no advisories or defects recorded is the entirety of the roadworthiness evidence available for this 2022 Mercedes-Benz GLB 200 AMG Line Premium Plus, so the mechanical story is one of clean compliance rather than a documented pattern of wear or component failure. With only one MOT on file, however, there is no multi-year history against which to verify long-term trends, and the absence of advisories is encouraging but limited in scope; the next test at the three-year point from registration will be the first real opportunity to see how suspension, brake, and underbody components are faring. For a vehicle of this class and premium specification, prospective buyers should treat the presentable record as a baseline rather than a comprehensive reassurance. At roughly 4,690 miles per year since 2022, this GLB has covered substantially less ground than typical for its age bracket, and the gap between registration and the first MOT in late 2025 indicates the car may have seen extended periods of standing rather than continuous light use. Low annual accumulation reduces wear on high-cycle consumables such as brake pads and discs, clutch friction material (less applicable here given the automatic transmission), and engine internal components, but it does shift attention toward items that degrade with time rather than mileage. Brake discs on lightly used vehicles are particularly prone to surface corrosion, while fuel systems, seals, and underbody protection can suffer from infrequent operation. Standing periods also accelerate tyre sidewall flex cracking and can stress the 12V battery and auxiliary systems, even on a relatively modern car. Given the absence of flagged components in the MOT record, the inspection focus should be on the items that typically present first on a GLB of this generation and which the test would only capture if they had already crossed the failure threshold. On the road, listen for clonks or knocks from the front suspension over speed humps and uneven surfaces, which can indicate wear in the lower control arm bushes, anti-roll bar drop links, or front strut mount bearings; a vague or wandering front end at speed may point to worn tie rods or top mounts. Brake feel should be firm and progressive from the first application, as seized caliper slide pins or pitted discs on a low-mileage car often manifest as a judder under heavy pedal pressure or a pulsing sensation rather than a warning light. Underbody and fluid checks are equally important given the low usage profile, even though no corrosion advisories were raised. Inspect the front subframe, brake pipes along the inner wings, and suspension arms for any early signs of surface rust, particularly around bolt heads and welded seams; pay close attention to the rear coil springs for any sign of corrosion pitting that could lead to fracture. Examine the engine oil and coolant on the dipstick and expansion tank respectively for any signs of emulsification or discolouration consistent with infrequent servicing, and check around the turbocharger oil feed lines and the front main seal for any residue of oil misting that may have accumulated during short, cold-running journeys. Finally, confirm that all electronic systems specific to the AMG Line Premium Plus trim, including the active park assist sensors, reversing camera, and adaptive cruise radar, function correctly, as these can be costly to recalibrate or replace if faults have developed during periods of disuse.
