2018 Mercedes-Benz A-Class 1.5L Diesel · L13 LBN

The most recent MOT test on August 13, 2025, confirms the vehicle remains roadworthy with no defects recorded at 52,828 miles. This represents a stable maintenance pattern over the past three years, with no recurring advisories or failures. The absence of defects in both the 2025 and 2023 tests suggests the vehicle has been subject to consistent, if not rigorous, servicing. However, the 2024 failure at 38,992 miles—despite passing just two weeks prior—indicates a brief but unexplained lapse in compliance. The subsequent tests in 2024 and 2025 passed without issue, implying the issue was either rectified or the vehicle was driven below the 12-month threshold before retesting. The mileage progression reveals a steady but moderate usage pattern, averaging around 6,600 miles annually. The gap between the 2022 and 2023 tests (15,081 miles in 12 months) is the most aggressive, while the 2024 failure at 38,992 miles—just 10,875 miles after the 2023 pass—suggests either a temporary reduction in mileage or a deliberate deferral of the test. The final 9,622 miles since the 2025 pass align with typical annual usage, though the lack of a 2026 test means no recent verification of critical systems. This could indicate the vehicle has been driven below the 12-month threshold or, less likely, has been stored without a test. Given the clean MOT history, priority should be given to inspecting high-wear components not directly tested by the MOT. The suspension—particularly rear bushes and coil springs—should be examined for excessive play or corrosion, as these are not routinely checked but critical for handling and safety. Brake discs and calipers warrant close scrutiny, especially if the 2024 failure was related to braking performance, though no specifics are recorded. Structural integrity, including underbody corrosion and wheel arch protection, should be assessed, given the vehicle’s age and typical exposure to road salt. Finally, verify the condition of the exhaust system for leaks or damage, as emissions-related failures are not always captured in the MOT but can indicate broader mechanical neglect.
