2007 Mercedes-Benz E 2.1L Diesel · BF57 ADV

The most recent MOT record from July 2023 reveals an unusual double-test scenario at 143,157 miles, where the vehicle passed once and failed once without any recorded defects. This suggests the failure was likely procedural—potentially due to a minor administrative oversight rather than a mechanical issue. The preceding test in May 2022 at 142,156 miles passed cleanly, indicating no persistent faults were carried forward. While the lack of defects in the latest tests implies no overt structural or safety-critical failures, the double-test anomaly warrants scrutiny, as it may hint at irregularities in the testing process or undocumented pre-test maintenance. Overall, the trend appears stable, though the recent history lacks depth to confirm long-term reliability beyond the past year. The vehicle’s mileage progression shows a consistent average of approximately 7,535 miles per year, which aligns with typical usage for its age. The gap between the 2022 and 2023 tests spans just over a year, with only 1,001 miles accumulated—a period of relatively low activity. This suggests the car was either lightly used or stood unused for extended periods, which could accelerate certain forms of wear, such as suspension perishing or brake fluid degradation. The absence of mileage spikes or drops indicates no extreme driving conditions, but the static periods may have allowed minor issues to develop undetected. Given the sparse defect history, a buyer should prioritise an in-person inspection of high-wear components that aren’t always captured in MOT tests. The suspension—particularly rear bushes and coil springs—should be examined for dryness or cracking, as prolonged inactivity can embrittle rubber and metal parts. Brake systems, including calipers and pads, warrant close inspection for uneven wear or binding, especially if the vehicle was stationary for long stretches, as this can lead to seized components. Structural integrity, particularly around wheel arches and sills, should be checked for corrosion, as Mercedes-Benz models of this era are prone to rust in these areas. Finally, the exhaust system and emissions controls should be visually inspected for leaks or damage, as these are often overlooked but critical for compliance and performance.
