2009 Mercedes-Benz C 2.1L Diesel · LM58 AYL

The vehicle presents a concerning mechanical profile characterized by a trend of worsening structural and suspension neglect. While the most recent test in November 2025 at 86,519 miles passed, it followed a failure for insufficient washer fluid and noted a worn rear lower arm bush. The November 2024 failure at 84,647 miles was particularly critical, revealing an inoperative engine management system light and extensive corrosion issues that suggest significant preventative maintenance has been deferred over several years. At 17 years old, the recorded 86,519 miles is remarkably low, averaging just over 5,000 miles per year. This low usage pattern explains the advanced physical degradation of rubber-based components, such as the perished tyres and perished suspension bushes noted between 2023 and 2024. However, the low mileage has not protected the vehicle from atmospheric oxidation, particularly on the rear subframe and brake pipework, which appear to be deteriorating due to age and environmental exposure rather than mechanical wear and tear. A buyer must prioritise a thorough physical inspection of the rear subframe and chassis mounts, as the record consistently flags corrosion across the subframe, lower sections, and coil springs. The 2024 report specifically noted that under trays prevented a full examination of the vehicle, which may have hidden deeper structural rot. The buyer should also assess the condition of all flexible brake hoses and ferrules, given that corrosion has been a recurring advisory for the last three tests. The suspension-related issues involving worn lower arms and seized brake pads indicate a history of reactive rather than proactive maintenance. Given the previous failure for an inoperative engine light in 2024, a professional diagnostic scan is essential to ensure the fault was properly rectified. While the low mileage is attractive, the documented evidence of structural rust and failing rubber components suggests the vehicle may require immediate investment to ensure long-term roadworthiness.
