2017 Mercedes-Benz A-Class 1.5L Diesel · AM66 BER

The most recent MOT on 10 March 2026 was a pass, with the only advisory being that the front brake disc shows wear, pitting or scoring but is not seriously weakened. Over the past six years the vehicle has repeatedly received advisories for front and rear brake disc wear and for tyre tread approaching the legal limit, and it suffered a dangerous failure in March 2022 due to a bulging off‑side front tyre. The pattern indicates a generally stable maintenance record – the dangerous tyre defect was corrected and the car has remained road‑legal – but the persistence of brake‑disc advisories suggests that the braking system has not yet been refreshed and will require attention in the near future. At 69 425 miles recorded for a 2017 model, the average annual mileage works out at roughly 7 700 miles per year, which sits comfortably within the typical UK usage envelope for a vehicle of this age. There are no obvious periods of unusually high mileage accumulation that would point to severe component fatigue, nor are there long gaps that might hint at prolonged storage. Consequently the wear observed on the brakes and tyres is more a function of normal use rather than accelerated degradation from excessive mileage. Prospective buyers should give the braking system a thorough examination. Visually inspect the front and rear discs for deep scoring, heat‑tinting or uneven wear, and measure the remaining thickness against the manufacturer’s minimum specification. During a test drive listen for any groaning or pulsation through the pedal, especially under moderate braking, which can signal that the discs are nearing the end of their service life or that the calipers are beginning to bind. Given the repeated tyre advisories and the prior bulge, both front tyres must be examined for tread depth, sidewall integrity and any signs of delamination; replacement of at least one front tyre is likely imminent, and the vehicle should be tested for vibration or shudder at higher speeds that would betray uneven wear or a developing defect. Beyond the brakes and tyres, inspect the suspension bushings, ball joints and tie‑rod ends for any looseness or knocking, as the car’s mileage suggests these components are entering the wear phase. Verify the condition of the 12‑volt battery, particularly its age and cranking performance, since a nine‑year‑old vehicle may have a battery approaching the end of its service life. Check that all fluid intervals – engine oil, coolant, brake fluid and gearbox oil – have been observed on the service book, and look for any signs of fluid leakage around the exhaust manifold, valve cover gaskets or rear differential. A comprehensive visual inspection of the under‑body for corrosion, especially around the wheel arches and suspension mounting points, will help confirm that the car has not spent excessive time standing idle, which can accelerate rust and affect structural integrity.
