2009 Mercedes-Benz C 2.1L Diesel · GF09 CKJ

The vehicle passed its most recent test on 20 November 2025 at 83,023 miles, yet the preceding failure on 18 November reveals significant underlying mechanical neglect. The tester initially rejected the car due to a leaking nearside rear brake pipe and an excessively corroded offside front brake pipe, alongside an inability to test brake performance. While repairs addressed these immediate failures to secure a pass, the persistence of multiple corrosion advisories on the remaining brake lines and rear coil springs suggests a worsening structural trend. Usage has been consistently low for a 17-year-old vehicle, averaging roughly 4,900 miles annually. The record shows a distinct increase in activity between November 2024 and November 2025, with the odometer rising from 74,996 miles to 83,023 miles. This 8,000-mile jump over a single year contrasts with the prior period, indicating the car is no longer sitting idle but is now accumulating distance at a rate that may accelerate wear on the ageing suspension and hydraulic components. A physical inspection must prioritise the braking system and chassis integrity. The history notes corroded brake pipes covered in grease and perishing front tyres, which points to age-related degradation rather than heavy wear. The rear coil springs were flagged for corrosion in late 2025, following severely deteriorated anti-roll bar dust covers recorded in 2023. These issues imply the vehicle has been exposed to moisture or stored in damp conditions, necessitating a close check for structural rust on the undercarriage before purchase.
