2009 Mercedes-Benz CLS 3.0L Diesel · FL09 ONW

The 2009 Mercedes-Benz CLS presents a highly stable and reassuring maintenance trend, culminating in a completely clean pass at its most recent MOT on 14 November 2025 at 85,967 miles. Recording zero defects across the last five consecutive annual tests demonstrates consistent mechanical integrity and diligent upkeep. This unblemished record indicates the vehicle has suffered no significant structural deterioration, braking faults, or suspension failures in recent years. The mileage accumulation aligns with light usage, averaging roughly 5,057 miles per year over its seventeen-year lifespan. Examining the chronological intervals reveals a period of minimal use between the November 2021 test at 79,441 miles and the November 2022 test at 80,120 miles, covering just 679 miles. Subsequent years show a steady increase in annual driving, climbing from 2,577 miles between 2022 and 2023 to 1,709 miles between 2024 and 2025. Such low mileage typically reduces wear on consumables and drivetrain components, though prolonged stationary periods can cause their own specific issues. Despite the flawless MOT history, a physical inspection must focus on the specific risks associated with a low-mileage, seventeen-year-old vehicle. Extended stationary periods often lead to perished rubber suspension bushes and deteriorating tyre sidewalls, even if tread depth remains legal. Inspect the brake discs for surface corrosion and check that the calipers have not seized from lack of use. Examine the exhaust system for moisture-induced corrosion and verify the structural integrity of the underbody, as older vehicles can be susceptible to corrosion over time.
