2015 Mercedes-Benz A-Class 2.1L Diesel · WM64 CFO

The 2015 Mercedes-Benz A-Class presented its most recent MOT test on 25 July 2025, achieving an overall pass with a minor defect noted for a damaged front windscreen that did not obstruct the driver's view, alongside an advisory concerning rear brake disc wear with pitting and scoring on both sides. Reviewing the documented DVSA history, the maintenance trend appears broadly stable but with minor recurring issues that warrant attention. The advisory concerning rear brake disc condition has now appeared in two consecutive tests, indicating progressive surface deterioration typical of a high-mileage vehicle. A previous failure on the same date in July 2021 for worn front brake pads down to the wear indicator was rectified at the same test, demonstrating that safety-critical components have been replaced in a timely fashion when required. With 154,720 miles recorded over approximately eleven years, this A-Class has covered an average of around 14,065 miles annually, which is notably high for its age and places above-average demand upon consumables, braking components, suspension items, and the drivetrain. The mileage progression across the MOT history shows consistent annual accumulation rather than long periods of standing, suggesting the vehicle has been in regular service. This level of usage accelerates wear on components such as brake discs and pads, tyres, and suspension linkages, while also implying that the engine, gearbox, and clutch have endured considerable working cycles. The relatively uniform mileage recorded between tests indicates the odometer reading is consistent and likely accurate. The recurring rear brake disc advisories from the 2024 and 2025 tests point to a need for inspection of both rear discs, as the pitting and scoring noted will progressively reduce braking efficiency and may eventually lead to replacement. On a test drive, listen for any brake shudder under firm application, particularly through the pedal, and observe whether the vehicle pulls to one side, which could indicate uneven disc wear or a binding caliper. The nearside rear coil spring corrosion advisory from 2021, while not resulting in a failure at the time, should be physically inspected for any further deterioration, as corroded springs can fracture and compromise ride height and handling. Symptoms of a failing coil spring include a noticeable drop on one corner, unusual clonks over uneven surfaces, or uneven tyre wear. Additionally, the offside rear tyre wear advisory from 2024, combined with the nearside front inner tyre advisory from 2023, suggests monitoring of wheel alignment and suspension geometry, particularly the bushes and wishbones, which can wear under high mileage. Given the vehicle's age and accumulated mileage, a prospective buyer should conduct a thorough physical inspection beyond the MOT record. Check all tyres, including the spare if fitted, for sidewall cracking or perishing consistent with age, even if tread depth remains legal, and verify that replacements are of consistent specification. Inspect the condition of the 12-volt battery, as Mercedes-Benz vehicles of this era are sensitive to voltage fluctuations which can trigger electrical warnings. Examine the underside, suspension arms, and subframe for corrosion, paying particular attention to the rear coil springs already flagged. Verify that the service book contains evidence of regular oil and filter changes at appropriate intervals, and confirm the timing belt or chain replacement history according to Mercedes-Benz schedule. Finally, request a pre-purchase inspection from a Mercedes-Benz specialist or a competent independent garage, focusing on the automatic gearbox operation, turbocharger function if applicable, and a diagnostic scan for any stored fault codes that would not surface during a standard MOT assessment.
