2022 Mercedes-Benz GLB 200 AMG Line Premium + A 1.3L Petrol · FD71 OBJ

The most recent DVSA MOT test for this 2022 Mercedes-Benz GLB 200 AMG Line Premium took place on 29 May 2026 and resulted in a Pass with no defects or advisories recorded, which represents the strongest possible outcome and suggests that the vehicle was returned to a roadworthy condition following the prior test. It is worth noting, however, that the immediately preceding test on 28 May 2026 was a Fail classified as Dangerous due to an offside rear inner tyre with ply or cords exposed, accompanied by an advisory for the nearside rear inner tyre being worn close to the legal limit and on its edge. The fact that the failure was remedied within a single day and a clean Pass was issued the following day indicates a prompt and effective repair rather than an underlying neglect problem, but the close succession of tests and the nature of the defect do warrant careful scrutiny by a prospective buyer. The maintenance trend overall appears stable but not without concern, as rear tyre wear of this severity on a relatively modern Mercedes-Benz SUV is unusual and may point to an alignment issue, suspension geometry irregularity, or simply a failure to rotate tyres at appropriate intervals. With a recorded mileage of 44,085 miles over approximately four years, the vehicle is averaging around 11,000 miles per year, which sits squarely within the typical range for a privately or lightly commercially used car of this age. There are no significant recorded gaps in the MOT history that would suggest extended periods of standing, and the mileage accumulation appears broadly consistent and steady rather than showing any sudden spikes or unusual drops. This kind of regular usage is generally favourable for mechanical longevity, as it tends to keep seals, brakes, drivetrain components, and the diesel particulate filter or petrol system working as intended and reduces the risk of corrosion from inactivity, though it does mean that consumable wear items such as tyres, brake pads, and discs should have been replaced or inspected at sensible intervals during the vehicle's life. Given the nature of the recent failure, a prospective buyer should pay particular attention to the condition and specification of all four tyres at the point of inspection, confirming that they are of matching size, load rating, and speed rating as recommended by Mercedes-Benz, and that they show even wear across their full width. The rear inner-edge wear pattern that prompted both the failure and the advisory can indicate a rear axle alignment issue, worn or sagging coil springs, failed or fatigued suspension bushes, or a problem with the multi-link rear suspension geometry typical of this model, so it would be prudent to take the vehicle for a thorough test drive over varied road surfaces, listening carefully for suspension knocks, clonks, or rear-end instability over bumps and during cornering. Any pulling to one side, wandering at speed, uneven or feathered tread wear across both axles, or a noticeable rear-end sag when loaded would be red flags suggesting that the underlying cause of the tyre wear has not been fully addressed. It is also worth inspecting the rear brake discs for uneven wear, corrosion pitting, or scoring, and verifying that the rear calipers are not binding, as seized or partially seized calipers are a common cause of uneven tyre wear on Mercedes-Benz vehicles and can manifest as a pulling sensation or reduced braking efficiency on test. Beyond the specific rear tyre and suspension considerations, a buyer of this four-year-old GLB with average mileage should still carry out the usual age- and calendar-based checks expected for any modern premium SUV. The 12V battery health should be verified, as Mercedes-Benz vehicles of this era are sensitive to voltage drops and can develop a wide range of electrical faults if the battery is marginal, and a failing battery often presents as random warning lights, infotainment glitches, or start-stop system malfunctions. Brake fluid should be confirmed as recently changed, as Mercedes-Benz typically specifies a two-year replacement interval regardless of mileage, and the engine coolant, transmission fluid, and any four-wheel-drive or differential fluids should be checked for evidence of recent service or at least be verified as being at the correct level and in clean condition on the dipstick. The underside of the vehicle should be examined for any signs of fluid leaks from the engine, transmission, or rear differential area, and the exhaust system should be inspected for corrosion at the joints and hangers, as UK road salt exposure can accelerate deterioration of the rear silencer and mounting rubbers. Finally, requesting evidence of the most recent full service, any previous tyre replacement invoices, and confirmation of the wheel alignment being checked following the May 2026 MOT failure would give meaningful reassurance that the tyre wear issue has been properly resolved rather than merely cosmetically patched.
