2009 Mercedes CLK 2.1L Diesel · BK09 WWB

The vehicle is currently roadworthy but the maintenance history reveals a worsening trend regarding structural and corrosion-related components. The most recent test in January 2026 at 110,216 miles identified significant corrosion on both the nearside and offside front brake pipes, which were obscured by grease, suggesting reactive rather preventative maintenance. While the car passed, the presence of general underbody corrosion at the rear indicates that the structural integrity is beginning to succumb to environmental degradation despite the relatively low mileage. At 110,216 miles over 17 years, the CLK has averaged approximately 6,500 miles per year, which is consistent with a low-useage profile. The data shows very short intervals between tests recently, with only 568 miles recorded between April 2024 and January 2026. This low annual mileage explains the accumulation of corrosion on various metal components and suggests the vehicle may spend long periods sitting stationary, which often leads to the perishing of rubber parts and accelerated oxidation rather than mechanical wear. A buyer must conduct a thorough physical inspection of the front suspension and steering assembly. The record shows recurring issues with the steering rack inner joints and front lower suspension arm bushes dating back to 2022 and 2023. Furthermore, the failure in March 2022 due to a fractured offside front coil spring and an excessively worn anti-roll bar pin highlights that the suspension-related components are a known point of failure for this example. The buyer should specifically check the rear spring mountings, which were flagged for corrosion in both 2023 and 2024. Specific attention is required for the brake lines and underbody condition. The tester flagged corroded brake pipes in the latest inspection, and the fact that they were covered in substances may have masked the extent of the rust. Given the documented history of general underbody corrosion and corroded anti-roll bars, a professional inspection is necessary to ensure that the rust has not progressed from surface areas to structural members. The history of perishing tyres in 2022 and 2023 also indicates that age-based components are reaching the end regardless of the low mileage recorded.
