2009 Mercedes S-Class 3.0L Diesel · GF09 CKO

The vehicle's overall roadworthiness remains stable, as evidenced by the consistent passing of the MOT in April 2025, despite the significant mileage accumulation that occurred since that test. This stability is supported by the fact that the vehicle has passed the test in June 2026, indicating that the current date falls within a normal maintenance window for this age group. The maintenance trend is not improving, nor is it worsening; rather, it is a steady state where the vehicle continues to meet the safety standards without requiring urgent intervention. Regarding the mileage pattern, the data shows a distinct gap between the 2025 test and the 2024 test, where the vehicle was tested at 220,110 miles in April 2025 and subsequently failed at 214,961 miles in March 2024. This 5,149-mile gap suggests that the vehicle was not maintained during the transition period, which could indicate a lack of regular servicing or a reliance on a specific maintenance schedule that was not kept up to date. The high mileage for a 2009 model, averaging approximately 12,948 miles annually, places the vehicle in a category where consumable wear is a primary concern, particularly on the drivetrain and suspension components. Given the recurring faults recorded in the 2024 and 2025 tests, specifically the excessive wear on suspension bushings, ball joints, and brake discs, the vehicle presents a significant risk to its structural integrity. The presence of oil leaks and corrosion on brake pipes suggests that the braking system is compromised, which could lead to sudden failure. While the engine condition in the 2024 test was acceptable, the engine MIL in the 2025 test indicates that the engine may be inoperable or malfunctioning, a condition that requires immediate attention to prevent catastrophic overheating. A buyer should inspect the chassis for structural corrosion and check the suspension bushings and ball joints for excessive play, as these components are prone to failure under the high mileage and wear patterns observed.
