MERCEDES-BENZ S-Class2013 · 3.0L Diesel

The vehicle’s most recent MOT on 2025-09-04 at 176,004 miles recorded a pass with no defects, but a prior failure on 2025-08-26 at the same mileage suggests unresolved issues. This abrupt shift from failure to pass without recorded defects raises concerns about the reliability of the testing process or potential temporary fixes. The absence of specific mechanical findings in both tests limits definitive conclusions, though the repeated testing within a month indicates potential underlying problems requiring further investigation. The vehicle’s mileage of 176,004 miles at 13 years old equates to approximately 13,539 miles annually, significantly above average for its age. This high usage rate likely accelerates wear on components such as brakes, suspension, and drivetrain. The MOT history shows consistent annual testing, with mileage increasing from 125,178 miles in 2022 to 176,004 miles in 2025, suggesting regular operation but no evidence of prolonged inactivity. The lack of defects in earlier tests does not preclude hidden deterioration, particularly in non-MOT-covered areas like exhaust emissions or structural integrity. A buyer should prioritize a detailed inspection of suspension components, including bushes and coil springs, which may show wear from high mileage. The failed 2025 test, even without recorded defects, warrants scrutiny of brake systems for binding calipers or uneven disc wear, common in vehicles with heavy use. Corrosion and exhaust system integrity should also be checked, as these are often overlooked in MOTs. The vehicle’s maintenance pattern suggests a need for thorough mechanical evaluation beyond the test records to confirm long-term reliability.
