MERCEDES-BENZ E350 AMG LINE BLUETEC PREM A2015 · 3.0L Diesel

The vehicle’s most recent MOT test on 2025-11-04 confirms it passed without defects at 31,119 miles, though it failed a preliminary check just two weeks earlier on 2025-10-22 at 31,102 miles. This abrupt failure followed by immediate re-passage suggests either a minor procedural oversight or a last-minute correction of a non-structural issue, as no defects were formally recorded. The preceding tests in 2024, 2023, and 2022 all passed cleanly with no advisories or faults, indicating a stable maintenance pattern over the past five years. However, the lack of any recorded issues does not preclude hidden wear—particularly in high-stress components like turbochargers, diesel particulate filters, or suspension mounts, which are common failure points in this model at this mileage. The recorded mileage of 31,119 miles over eleven years—approximately 2,829 miles annually—is unusually low for a vehicle of this age, suggesting either minimal use or prolonged periods of inactivity. The gap between the 2022 and 2023 tests (289 days) and the 2024 and 2025 tests (365 days) aligns with standard MOT intervals, but the abrupt failure followed by re-testing in late 2025 warrants scrutiny. Such low mileage can mask deeper issues, as components may not have endured sufficient stress to reveal wear patterns. Conversely, it may also imply the vehicle was stored in conditions that could have accelerated corrosion or degraded fluids. Given the absence of recorded defects, a prospective buyer should prioritise an independent inspection of the turbocharged diesel system, particularly the turbocharger bearings and intercooler hoses, which are prone to failure in this model. The suspension should be closely examined for worn or leaking bushes, particularly at the rear, where AMG-tuned vehicles often experience premature deterioration. Brake calipers and discs should be checked for uneven wear or binding, as the 2025 failure—though unexplained—could hint at a recurring issue. Structural integrity, especially around the sills and wheel arches, should be assessed for corrosion, given the vehicle’s age and potential exposure to road salt or moisture. Finally, the diesel particulate filter (DPF) and exhaust system should be inspected for clogging or leaks, as these are common failure points in BlueTec-equipped Mercedes.
