2009 Mercedes-Benz E 2.1L Diesel · NG09 EWB

This Mercedes-Benz E, tested most recently on August 8, 2023, currently holds a valid MOT with no recorded defects. The test history reveals an unusual pattern: two consecutive failures in July 2023, both without specific faults logged, followed by a pass in August of the same year. While the most recent test is over three years old—far exceeding the standard 12-month validity period—there is no evidence of recurring mechanical issues in the official record. The absence of advisories or repeated failures suggests the vehicle was either driven to a test centre for a routine check or the failures may have been administrative in nature. However, the lack of recent testing raises questions about whether critical components, such as suspension bushes or brake calipers, have been inspected or replaced since 2023. The recorded mileage of 135,645 miles over approximately 17 years equates to an average of around 8,000 miles annually, which is typical for a vehicle of this age. There are no significant gaps or spikes in the data to suggest prolonged neglect or rapid wear, though the sparse MOT history—with only four entries spanning five years—limits visibility into long-term maintenance habits. The most notable irregularity is the two back-to-back failures in July 2023, which could imply either a temporary administrative oversight or a brief period of uncertainty before the vehicle passed in August. Without additional service records, it is impossible to confirm whether routine maintenance, such as fluid changes or brake inspections, has been consistently performed. Given the lack of specific faults in the MOT history, a buyer should prioritise an independent inspection of high-wear components that are not routinely covered by the test. The suspension system—particularly the rear bushes and coil springs—should be examined for excessive play or corrosion, as these are common failure points in high-mileage Mercedes-Benz models. Binding or unevenly worn brake calipers, particularly on the rear, warrant close scrutiny, as the test centre’s failure in July 2023 may have been related to such issues. Structural integrity, including underbody corrosion around the sills and wheel arches, should also be assessed, as this is a critical but often overlooked aspect of roadworthiness in older vehicles. Finally, the exhaust system should be checked for leaks or excessive rust, as catalytic converter failures are not tested under MOT but can lead to costly repairs. The absence of advisories does not guarantee these areas are sound, so a thorough mechanical examination is essential.
