2017 Mercedes-Benz A-Class 1.5L Diesel · OV67 WHD

The latest MOT test conducted on 9 July 2025 resulted in a pass, contributing to a maintenance trend that appears exceptionally stable. While the records indicate failures in both 2024 and 2025, the absence of listed defects suggests these were either minor administrative discrepancies or immediate rectifications. The total lack of advisories over the last three years is a positive indicator, suggesting the vehicle has been maintained to a high standard and that wear and tear on critical safety components has been managed proactively. With 74,341 miles recorded over approximately nine years, the vehicle has averaged roughly 8,260 miles per annum. This represents typical usage for a premium hatchback of this vintage, indicating a balanced operational history. This mileage profile is generally ideal as it avoids the accelerated wear on the drivetrain, suspension, and interior trim associated with high-mileage examples, while simultaneously avoiding the mechanical stagnation and seal degradation often found in vehicles that have suffered from prolonged periods of inactivity. Given the clean MOT history, the inspection should focus on age-related degradation and calendar-based maintenance. A physical examination of the tyres is essential; the buyer should check the sidewalls for perishing or fine cracking, as rubber degrades over time regardless of tread depth. The brake discs should be inspected for surface corrosion or pitting, and the calipers checked for binding to ensure consistent braking performance. Additionally, the health of the 12V battery should be verified, as the complex electrical systems in this model are sensitive to voltage drops as batteries age. The buyer must also scrutinize the service records to ensure that time-based fluid intervals have been strictly observed. Engine oil, brake fluid, and coolant degrade over time, and adherence to the manufacturer's schedule is vital for the longevity of the engine and turbocharger. During the test drive, listen for any subtle clunks from the suspension bushes or coil springs and ensure the transmission shifts are seamless. Confirming that the lack of MOT advisories is supported by a comprehensive service history will provide the necessary assurance regarding the vehicle's long-term mechanical integrity.
