2017 Mercedes-Benz A-Class 1.5L Diesel · AC05 ASH

The vehicle most recently passed its MOT on 8 May 2026, but the overall maintenance trend has shifted from stable to concerning over the last few years. While earlier tests were clean, the most recent records indicate a pattern of neglecting consumable components. The transition from a dangerous failure regarding tyre tread in 2025 to widespread brake advisories in 2026 suggests a reactive approach to vehicle upkeep rather than a preventative one, which may indicate other deferred maintenance. With a recorded mileage of 69,429 miles over approximately nine years, the vehicle has averaged around 7,714 miles per annum. This is considered typical usage for a vehicle of this age and class. Mechanically, this mileage means the car is entering a phase where standard wear-and-tear items, such as suspension bushes, coil springs, and drivetrain mounts, may begin to show signs of fatigue, though it has avoided the extreme wear associated with high-mileage motorway vehicles or the degradation seen in cars that have stood for extended periods. Prospective buyers should prioritise a thorough inspection of the braking system. The current advisories for pitted, scored, and worn discs and pads on both the front and rear axles indicate that a full brake overhaul is imminent. During a test drive, be alert for brake shudder or a pulsing sensation through the pedal, which often accompanies scored or warped discs, as well as high-pitched squealing indicative of thin pads. The presence of pitting suggests the discs may have suffered from surface corrosion, which can compromise braking efficiency and pedal feel. Attention must also be paid to the tyres and wheel alignment. The history of dangerous tread depth failures and previous advisories for outer edge wear suggests a potential issue with the front-end tracking or a lack of regular tyre rotation. Inspect the current tyres for uneven wear patterns across the tread width and check the sidewalls for any cracking. Given the recent neglect of consumables, it is essential to verify the service history for evidence of calendar-based fluid changes, specifically the engine oil and brake fluid, to ensure the internal mechanical integrity has not been compromised by extended service intervals.
