2010 Mercedes-Benz CLS 3.0L Diesel · FD10 VDX

The 2010 Mercedes-Benz CLS received its most recent MOT test on 2024-02-26, where it passed with several advisories relating to the front suspension ball joints, both offside and near-side, each exhibiting slight play indicative of wear beyond the legal minimum but not yet severe enough to fail the test. This follows a consistent pattern in the MOT history, with the same advisories recurring in 2023-03-06, suggesting a stable but ongoing issue rather than a sudden deterioration. The failure in 2021-12-03—particularly the tyre wear advisories and headlamp alignment major—was an outlier, likely due to either a period of higher mileage accumulation or less frequent maintenance, but subsequent tests have shown the vehicle’s roadworthiness has been restored. The recurring suspension advisories, however, indicate that the vehicle’s suspension system is under stress and will require proactive attention to prevent further degradation or potential failure. The recorded mileage of 162,463 miles for a vehicle aged 16 years represents a reasonable annual usage rate of approximately 10,154 miles per year, which is typical for a car of this age and class. This level of mileage suggests a moderate to heavy usage profile, with no apparent dramatic spikes or long periods of inactivity that might have exacerbated wear in specific systems. While lower mileage could imply less wear on consumables like fluids and brakes, higher mileage tends to accelerate the deterioration of suspension components, drivetrain elements, and internal engine wear over time. The absence of significant mileage gaps in the MOT history supports the likelihood of consistent usage, but the wear observed in the suspension ball joints and steering rack joints aligns with the expected progression for a vehicle with this mileage. For prospective buyers, the most critical areas to inspect during a physical examination and test drive are the front suspension components, particularly the upper and lower suspension arms, ball joints, and steering rack. Slight play in the ball joints, as noted in the MOT advisories, may cause a clunking or rattling noise when the vehicle is driven over bumps or corners, and excessive movement could lead to misalignment of the steering or uneven tyre wear. Listen for any persistent clunks or thumps from the front suspension during acceleration and braking, and check for uneven tyre wear patterns, which may indicate misalignment or suspension misalignment. Additionally, verify that the steering feels responsive without excessive resistance or binding, as play in the steering rack can lead to poor handling and potential alignment issues. Impending maintenance should include replacing the worn suspension ball joints and steering rack inner joints within the next 5,000 to 10,000 miles, depending on the severity of the wear, to prevent further deterioration and ensure safe operation. Beyond the suspension, the tyre advisories from the 2021 MOT—particularly the near-edge wear on the rear tyres—highlight the importance of a thorough tyre inspection. While the tyres have since been renewed, buyers should confirm that the tread depth is adequate and check for signs of sidewall damage or perishing, which can compromise safety, especially at higher speeds. The vehicle’s age and usage profile also warrant a check on the brake system for signs of corrosion or binding calipers, particularly if the car has been stationary for prolonged periods, as standing brake discs can corrode and cause binding during braking. Inspect the brake fluid for contamination or low levels, as brake fluid degrades over time and can lead to hydraulic failure. Lastly, given the vehicle’s age, verify that the service book records are up to date, particularly for fluid servicing (oil, coolant, brake fluid, and transmission fluid), as these fluids degrade over time regardless of mileage. A calendar-based service interval of every 2 years or 30,000 miles is recommended for fluid checks, and a full service every 60,000 to 100,000 miles is advisable for a vehicle of this age to maintain reliability.
