2017 Mercedes-Benz A-Class 1.5L Diesel · LL67 ADV

The 2017 Mercedes-Benz A-Class shows a stable roadworthiness trend with no defects recorded across its most recent MOT tests, including the April 2025 pass at 69,960 miles. The sole failure in May 2024—curiously at the same mileage as the preceding pass—appears anomalous rather than indicative of a recurring issue, as no defects were logged. The vehicle’s last test occurred just over a year ago, which is acceptable but not ideal for a car of this age, as critical components like suspension bushes, brake calipers, and exhaust systems may degrade beyond MOT thresholds in that period. The absence of advisories in any test suggests no hidden or deferred concerns were noted by the tester. Mileage progression reveals a consistent pattern of roughly 7,800 miles annually, which is typical for a vehicle of this age and usage class. The gap between the September 2022 test at 33,937 miles and the May 2023 pass at 37,662 miles—just over 3,700 miles in eight months—indicates no prolonged periods of inactivity. However, the rapid accumulation of 15,000 miles between May 2023 and May 2024 suggests either heavy usage or a change in ownership, which could accelerate wear on high-mileage components. The most recent 15,921 miles since April 2025 aligns with this trend, though the lack of advisories in the latest test does not preclude unseen deterioration in areas like coil springs, brake pads, or steering dampers. Given the clean MOT history, a buyer should prioritise an independent inspection of suspension integrity, particularly the rear coil springs and bushes, which are common failure points in this model. The binding brake caliper advisory from the 2024 failure—despite the pass—warrants verification of rear brake function and pad thickness, as repeated binding can indicate warped discs or seized hardware. Exhaust emissions should also be checked, as the 2024 failure may have been a sensor or catalytic converter issue masked by subsequent tests. Structural corrosion, especially around wheel arches and sills, should be inspected, as the vehicle’s age and mileage increase the risk of hidden rust compromising body panels or subframes. Tyre condition, despite no MOT failures, should be scrutinised, as the 2023 and 2024 tests suggest either inconsistent tread depth monitoring or recent replacements.
