2015 Mercedes-Benz E 2.1L Diesel · Y28 NAJ

The vehicle’s most recent MOT test on 17 December 2025 at 74,382 miles passed without any defects, confirming it remains roadworthy under current UK standards. The consistent pass history over the past three annual tests—with no advisories or failures—suggests a stable maintenance record, though the single failure in December 2023 at 52,508 miles (just 77 miles before passing the next day) appears anomalous and lacks explanatory defects. The absence of recurring issues in brakes, suspension, or emissions indicates no obvious pattern of neglect or deferred repairs. However, the 2023 failure date is unusually close to the subsequent pass, which warrants scrutiny of whether the vehicle was driven under test conditions or if minor oversights were overlooked. The mileage progression shows a steady average of approximately 6,762 miles per year, which aligns with typical usage for a vehicle of this age. There are no significant gaps or abrupt jumps in mileage between tests, though the 2023 failure followed closely by a pass suggests either a brief period of light use or a rushed inspection. The lack of advisories in any test implies no deferred maintenance was flagged by the tester, though this does not preclude hidden issues in components like suspension bushes or drivetrain seals. Given the clean MOT history, a buyer should prioritise an independent inspection of suspension components—particularly rear bushes and coil springs—due to the vehicle’s age and mileage. The brakes, while never failing, should be checked for uneven wear or binding calipers, as repeated high-mileage use may have contributed to subtle degradation. Exhaust emissions were never flagged, but a visual inspection of the catalytic converter and oxygen sensors is advisable, given their susceptibility to clogging or failure over time. Structural integrity, especially around wheel arches and sills, should also be examined for corrosion, as this is a common concern for Mercedes-Benz models of this era. The 2023 failure, though unexplained, hints at the possibility of a minor oversight in testing, so verifying recent service records for brake fluid changes, timing belt condition (if applicable), and fluid leaks would provide further reassurance.
