2011 Mercedes-Benz E 3.0L Diesel · ND11 SYU

The vehicle’s most recent MOT test on 2025-11-25—just six months ago—confirms it passed without defects, though it failed the prior test on 2025-11-11 at nearly identical mileage (149,856 vs. 150,650). This abrupt reversal suggests either a last-minute repair or a minor oversight in the test itself, as no defects were logged in either instance. The pattern remains stable over the past three years, with consistent annual testing and no recurring advisories or major failures beyond these two consecutive passes and fails. The absence of any advisory notes implies no ongoing issues were noted by testers, though the lack of defects on failure could indicate a technicality rather than a genuine mechanical concern. Mileage progression shows a steady accumulation of approximately 10,000 miles annually, which aligns with typical usage for a vehicle of this age. The gap between the 2024 and 2023 tests (around 5,000 miles) suggests the car was either stored briefly or driven lightly during that period, but no extended inactivity is evident. There are no red flags in the mileage pattern—no sudden spikes or prolonged stagnation—that would warrant further suspicion of neglect or misuse. Given the lack of recorded defects or advisories, the most prudent areas for an in-person inspection would focus on high-wear components typically overlooked in MOT testing. The suspension system—particularly coil springs, bushes, and shock absorbers—should be scrutinised for uneven wear or fluid leaks, as these are common failure points in older Mercedes-Benz models. Brake systems, including calipers, pads, and discs, should be checked for uneven wear or binding, especially if the vehicle was driven through wet or heavy conditions between tests. Structural integrity, particularly around wheel arches and underbody, should be examined for corrosion, as this is a critical but often silent risk in vehicles of this age. Finally, the exhaust system should be inspected for leaks or excessive rust, as these can affect emissions and structural stability over time.
