2009 Mercedes-Benz CLK 1.8L Petrol · TY06 RAW

The most recent MOT test on the 2009 Mercedes-Benz CLK was conducted on 2025-08-13, resulting in a passing outcome, though it did not entirely clear the vehicle of its previous issues. The trend in maintenance history reveals a pattern of recurring, critical mechanical failures that have persisted over the past few years, particularly in the suspension and braking systems. The 2025 test alone highlighted deteriorating brake hoses on both the near and offside rear, which are advisory defects but indicate a developing risk of failure if left unaddressed. The failure in 2025-08-08 was more severe, with major defects including a fractured front coil spring and excessively worn ball joints on both sides of the front suspension, which are critical components that compromise vehicle handling and stability. These repeated failures suggest either a lack of timely maintenance or underlying structural wear that has not been adequately mitigated, warranting cautious optimism that the latest MOT reflects either improved condition or a temporary reprieve from deeper issues. The vehicle’s recorded mileage of 101,912 miles at the time of this assessment is unusually low for its age, standing at approximately 5,995 miles per year—a rate that is far below the expected wear rate for a car of this vintage. Such low mileage can result from prolonged periods of inactivity, particularly if the vehicle has been stored without regular use, which can exacerbate issues like corrosion, fluid degradation, and component stiffness. However, the absence of higher mileage accumulation does not necessarily mean the vehicle is well-maintained; instead, it may indicate that wear has been deferred, potentially leading to more severe failures when the car is eventually put into regular service. The suspension and braking systems, in particular, are prone to accelerated deterioration when a vehicle stands idle for extended periods, as seen in the repeated MOT failures. Given the recurring suspension and braking defects, the prospective buyer should conduct a thorough inspection of the front and rear suspension components. Focus on the front coil springs, which were fractured in 2025-08-08, and the ball joints, which were excessively worn—both symptoms of significant mechanical stress. During a test drive, listen for unusual clunks or rattles from the suspension, particularly when the vehicle is driven over bumps or at speed, which may indicate loose or failing components. The brake system should be inspected for any signs of vibration, pulsation, or reduced braking efficiency, as well as checking for fluid leaks around the brake hoses, which were noted as slightly deteriorated in the latest MOT. Additionally, visually inspect the brake discs for warping, scoring, or excessive thickness wear, and ensure the calipers are not binding, which could lead to uneven braking performance or premature failure. For the buyer, the vehicle’s age and low mileage profile necessitate a more rigorous inspection than a typical high-mileage car, as age-related issues like tyre sidewall perishing, standing corrosion, and fluid degradation from lack of use can be more pronounced. Begin with a visual check of the tyres for cracks or perishing in the sidewall, which can compromise structural integrity, especially if the vehicle has been stored for long periods. The 12-volt battery should be tested for charge retention and physical condition, as prolonged disuse can lead to corrosion or internal failure. The engine bay and undercarriage should be inspected for signs of rust, particularly around wheel arches, exhaust systems, and suspension mounts, which are common areas for corrosion to develop. Fluid levels should be checked, with particular attention to the brake, coolant, and transmission fluids, as these can degrade over time even without regular use. If the vehicle has not been serviced according to the manufacturer’s schedule, verify the presence of any service book stamps or records for oil changes, filter replacements, and timing belt servicing, as these are critical for long-term reliability. Finally, a professional inspection by a qualified mechanic should be arranged to assess the condition of the suspension components, brakes, and other high-wear areas that have been flagged in the MOT history, ensuring no underlying issues have been overlooked.
