2022 Mercedes-Benz GLB 200 AMG Line Premium Auto 1.3L Petrol · YR22 BNB

The most recent DVSA MOT test on 2026-07-30 resulted in a passing outcome, with the only recorded minor issue being a windscreen damage that did not impair the driver’s field of vision. However, the vehicle’s MOT history reveals a pattern of recurring defects that warrant careful attention. The two most notable failures occurred in February 2024 and February 2026, both involving major issues such as a horn malfunction and a serious offside rear shock absorber fluid leak, alongside advisories like tyre nail damage and a failing windscreen washer system. These repeated failures suggest either a persistent mechanical vulnerability or a lack of timely maintenance, particularly in critical areas like the suspension and electrical systems. The vehicle’s ability to pass subsequent tests—including the clean record in March 2025—implies that either corrective action was undertaken between failures or the underlying issues were not as severe as initially reported. Nonetheless, the presence of advisories and recurring minor defects indicates that the vehicle may still have latent concerns that require thorough inspection before purchase. The recorded mileage of 17,966 miles for a 2022 model year is unusually low for its age, averaging just 4,492 miles annually—a rate that is significantly below the typical usage expected for a vehicle of this class. Such low mileage can result from prolonged periods of inactivity, particularly if the vehicle has been stored for extended periods without regular movement. This could lead to several potential issues, including the degradation of fluids such as brake fluid, differential fluid, and coolant over time, as well as the risk of corrosion in components like the brake system, suspension, and electrical connections. Additionally, standing vehicles are prone to brake disc corrosion, particularly if they have been stationary for months, which may cause binding calipers or uneven wear patterns. Tyres, while not excessively worn, may still exhibit signs of sidewall cracking or perishing due to age-related vulcanisation breakdown, even at low mileage. The absence of recent high-mileage usage means that consumables like oil, filters, and spark plugs may not have been replaced according to manufacturer recommendations, further increasing the likelihood of hidden wear or failure. For a prospective buyer, this vehicle’s MOT history and low mileage profile necessitate a rigorous pre-purchase inspection to address both immediate and latent concerns. Begin by examining the suspension system, particularly the offside rear shock absorbers, which failed an MOT due to fluid leakage. Listen for excessive clunking or rattling during cornering or over bumps, and check for uneven tyre wear or a sagging ride height, which may indicate worn springs or damaged suspension bushes. The horn failure from the February 2024 MOT failure should be verified by testing its operation, as electrical faults can persist even after passing subsequent tests. Inspect the brake system for corrosion on discs and linings, especially if the vehicle has been stationary for extended periods, and check for binding calipers or uneven braking performance. Fluid levels should be topped up to manufacturer specifications, with particular attention to brake fluid, differential fluid, and coolant, as standing can cause degradation. Additionally, verify the condition of the windscreen washer system and ensure the washer fluid reservoir is full and functional, as the 2024 failure suggests a recurring issue. Finally, assess the tyre condition for sidewall damage, tread depth, and signs of uneven wear, as the offside rear tyre advisory from 2026 may indicate a need for closer inspection. As for practical checks relevant to its age and low mileage, focus on the vehicle’s overall structural integrity, fluid condition, and electrical systems. Given the extended periods of inactivity, check for signs of standing corrosion on the chassis, undercarriage, and any exposed components, particularly around the wheel arches, exhaust system, and brake calipers. The 12V battery should be tested for charge capacity and terminal cleanliness, as prolonged disuse can lead to sulphation or reduced performance. Inspect the exhaust emissions system for leaks or excessive backpressure, which could indicate catalytic converter or manifold issues, though this is less critical for a GLB 200 AMG with its modern emissions controls. Verify that all service book stamps are up to date, especially for fluid changes, spark plug replacements, and timing belt servicing, as these are critical for long-term reliability. Lastly, conduct a thorough test drive to evaluate handling, braking, and acceleration for any unusual noises or performance anomalies, as these may reveal deeper mechanical issues not caught by the MOT. If the vehicle has been stored in a damp or extreme environment, additional checks for mould growth in the cabin or undercarriage may be necessary.
