2021 Mercedes-Benz A 1.9L Diesel · KS21 ABU

The vehicle most recently passed its MOT on 27 August 2026, continuing a consistent trend of roadworthiness with clean passes in both 2024 and 2025. While the most recent inspection has introduced a couple of advisories, the overall maintenance trajectory remains stable. The absence of previous failures suggests a vehicle that has been kept in a condition meeting the minimum legal safety standards without recurring systemic faults. With a recorded mileage of 42,779 miles over approximately five years, the vehicle has averaged around 8,556 miles per year. This represents a typical usage profile for a modern hatchback, suggesting a balanced mix of urban and motorway driving. This level of accumulation is unlikely to have caused premature fatigue in the drivetrain or structural components, though it brings the vehicle into a window where standard wear and tear items such as brake pads and cabin filters will require monitoring. Regarding the recent advisories, the offside front tyre is noted as being worn to 2mm, which is approaching the legal minimum of 1.6mm. A prospective buyer should inspect the tread depth across the width of the tyre to determine if the wear is even or concentrated on the edge, as the latter would indicate a requirement for a four wheel alignment check. During a test drive, listen for any rhythmic humming or vibration that could suggest uneven tyre wear or a developing wheel bearing issue. The mention of an undertray obstructing the inspector's view means certain underside components were not fully verified. It is advisable to perform a visual check for any weeping fluids or signs of corrosion on the chassis and suspension mounting points. Given the vehicle's age, you should also verify the service history to ensure oil changes have been performed according to the manufacturer's intervals and check the brake discs for any significant lipping or surface corrosion. Finally, ensure the 12V battery is holding a strong charge, as modern Mercedes-Benz electronics are sensitive to voltage drops.
