2008 Mercedes-Benz CLS 3.0L Diesel · AV08 ROU

The most recent MOT inspection on 18 February 2026 resulted in a pass, but the vehicle's maintenance history indicates a concerning trend of deteriorating steering and suspension components. While the vehicle has successfully passed its recent tests, the frequency and nature of the advisories suggest that mechanical wear is progressing across several critical systems. The transition from major failures in previous years to a series of multiple advisories in the latest test indicates that while the vehicle is being kept roadworthy, it is currently at a stage where multiple component replacements will soon be necessary to maintain safety and handling standards. With 124,701 miles recorded over approximately 18 years, this Mercedes-Benz CLS has averaged roughly 6,928 miles per year. This is considered low to moderate annual usage, which is typical for a premium grand tourer. While lower mileage generally implies less drivetrain wear, it can often lead to other age-related issues such as rubber component degradation and fluid stagnation. In this specific case, the mileage profile aligns with the observed deterioration of suspension bushes, ball joints, and tyre sidewalls, where the lack of high-speed motorway running may have contributed to the perishing of rubber elements and the accumulation of corrosion on brake lines and springs. A prospective buyer must pay close attention to the steering and front-end geometry during a test drive. The recent advisories regarding play in the nearside and offside drag link end ball joints, as well as the nearside front lower suspension arm ball joint, are significant. You should listen for rhythmic clunking or knocking sounds when driving over uneven road surfaces or when turning the steering wheel at low speeds. Additionally, the advisory for a worn steering column top bearing may manifest as a vague or notched sensation through the steering wheel. Given the history of steering rack play noted in previous years, any wandering sensation at cruising speeds or a lack of precision in direction changes should be treated as a sign of impending steering system failure. The braking system and tyre condition also require immediate scrutiny. The history of corroded brake pipes and corroded hoses suggests that the hydraulic lines are nearing the end of their reliable service life; check for any signs of weeping fluid or excessive surface corrosion on the metal lines. The advisory regarding an offside front tyre showing signs of cracking or perishing indicates that the rubber is losing its structural integrity due to age rather than tread wear. Inspect all tyres for sidewall perishing and ensure the tread depth is sufficient. Furthermore, given the history of corroded coil springs, you should visually inspect the rear suspension for heavy scaling or fractures, as spring failure can lead to sudden vehicle instability.
