2009 Mercedes-Benz C 2.1L Diesel · SP09 RKA

The most recent MOT test for this 2009 Mercedes-Benz C-class occurred in August 2023, where it failed due to a critical ABS fault and a fractured offside front coil spring, alongside persistent near-side seat belt webbing damage. The preceding MOT history reveals a pattern of recurring issues, particularly in the braking system and suspension components, with multiple failures in 2019 and 2023, indicating a concerning trend of mechanical degradation rather than stable maintenance. While earlier MOTs in 2020 and 2021 were clean apart from minor advisories, the vehicle’s overall condition suggests that wear and tear have progressed significantly over its 17-year lifespan, warranting cautious acquisition. The presence of advisories such as corroded brake pipes, worn suspension bushes, and binding rear service brakes further underscores the need for thorough pre-purchase inspection, as these conditions could escalate into major failures if left unaddressed. The vehicle’s recorded mileage of 192,652 miles over approximately 17 years represents an average annual usage of around 11,332 miles, which is typical for its age and class. However, the combination of this mileage with the MOT history suggests that the car has likely undergone periods of prolonged inactivity, potentially leading to additional wear from standing corrosion, particularly in the brake system and suspension components. Higher mileage generally accelerates consumable wear—such as brake pads, suspension bushes, and wheel bearings—but the vehicle’s age and the presence of multiple advisories related to corrosion and binding mechanisms indicate that fluid degradation and structural fatigue may also play significant roles. The 2019 failure for parking brake inefficiency and the 2023 ABS fault further imply that the braking system has been subjected to stress, potentially from frequent use or improper maintenance. For a prospective buyer, this vehicle requires a meticulous pre-purchase inspection to assess the severity of the recorded defects and their mechanical implications. Focus on the offside front coil spring fracture , which is a major structural failure and will necessitate immediate replacement, as it compromises ride quality and handling stability. During a test drive, listen for unusual suspension clunks or uneven ride height, which may indicate further suspension component wear. The ABS fault should be addressed promptly, as it may stem from failing sensors or wiring, leading to reduced braking effectiveness or even a complete loss of ABS functionality. Inspect the corroded brake pipes —particularly near the front and rear—checking for leaks, which could indicate internal corrosion or mechanical failure, and confirm that the brake system has been recently serviced to ensure fluid freshness. The binding rear service brakes and parking brake inefficiency suggest that the rear brake calipers or mechanisms may be seized or worn, leading to inconsistent stopping power; test for uneven brake pad wear or a spongy or uneven brake pedal feel. In addition to the above, conduct a thorough visual and functional check of the seat belt webbing , as fraying or damage can compromise occupant safety. The wheel bearings with slight play noted in 2019 and 2020 should be inspected for excessive noise or vibration, particularly at low speeds or when cornering, as this could indicate impending failure. The undertray fitted in 2019 may offer some protection against road debris, but it should be checked for damage or wear that could expose critical components to corrosion or impact. For age-related checks, examine the tyres for sidewall cracking or perishing, which can occur even at moderate mileage due to prolonged exposure to UV light and road salt. Verify the 12V battery health and ensure all electrical connections are tight, as the vehicle’s age and potential corrosion risks may affect starter and accessory performance. Finally, confirm that the service book has been updated, particularly for fluid servicing—oil, brake fluid, and coolant—since these degrade over time regardless of mileage. If the vehicle has been stored for extended periods, check for standing corrosion on the undercarriage, particularly around wheel arches and exhaust components, and ensure all fluids are topped up to prevent further degradation.
