2015 Mercedes-Benz Citan 1.5L Diesel · WM65 BHE

The most recent MOT tests on this 2015 Mercedes-Benz Citan, conducted just three months ago on 8 April 2026, reveal an unusual but technically stable roadworthiness pattern. Despite two consecutive tests at 166,823 miles—one passed, one failed without recorded defects—the absence of recurring advisories or defects suggests the vehicle was either driven to the test centre in a minimal condition or the failure was procedural (e.g., minor administrative oversight). The lack of any structural or mechanical advisories in the past three tests implies no progressive issues with suspension bushes, coil springs, or binding calipers, which are common failure points at this mileage. However, the repeated failures at the same mileage without explanation warrant scrutiny of whether the vehicle was genuinely roadworthy at the time or if the tests were conducted under non-standard circumstances. The recorded mileage of 166,823 miles over approximately 11 years—averaging around 15,166 miles annually—indicates unusually high usage for a vehicle of this age. The gap between tests is consistent, with roughly 11,000 miles between each MOT, suggesting regular but aggressive driving. Notably, there is no evidence of prolonged periods of inactivity, which could have mitigated wear on components like the exhaust system or fuel injection. The most recent test occurred just three months ago, which is well within the 12-month MOT cycle, but the dual test at the same mileage raises questions about whether the vehicle was maintained between these dates or if critical components were overlooked. Given the lack of advisories in the MOT history, a buyer should prioritise an independent inspection of high-wear items that are not routinely tested under MOT regulations. Focus on the suspension system—particularly the rear trailing arms and control arms for excessive play or corrosion—and the brake system, including rear brake discs for uneven wear or binding. The high mileage also increases the likelihood of minor corrosion in wheel arches or underbody components, so a thorough examination of structural integrity is advisable. While the MOT record does not indicate major failures, the repeated test anomalies at the same mileage suggest a need for verification of service history, particularly for items like timing belt tensioners, differential fluid levels, and fuel injection health, which are not covered by the MOT but critical for long-term reliability.
