2009 Mercedes CLK 2.1L Diesel · BJ09 HWD

The vehicle is currently roadworthy but the maintenance history reveals a trend of reactive rather than preventative care. While the car passed its most recent test in November 2025 at 177,880 miles, this followed a significant failure just two weeks prior. The record indicates a persistent struggle to address aging components, particularly within the braking system and suspension. Despite the pass, the recurring nature of corrosion advisories on brake pipes and structural members suggests that parts are only replaced once they reach a point of failure or near-failure status. At 177,880 miles over 17 years, the Mercedes averages approximately 10,464 miles per year, which is consistent with typical usage for a luxury coupe of this age. The data shows a high frequency of testing between November 2023 and November 2025, where the vehicle covered over 4,000 miles in two years. This consistent mileage explains the steady wear on rubber components and metal surfaces, but the rapid succession of failures during this period suggests the vehicle was pushed to the limits of its current mechanical condition. A buyer must conduct a thorough inspection of the rear sub-frame, which was flagged as corroded in both the 2024 and 2025 tests. While the tester did not deem it seriously weakened, structural rust on Mercedes chassis often progresses rapidly once. The steering rack also requires attention, as play in the inner joints has been noted consistently since 2023 and 2024 without a recorded repair. This indicates a significant mechanical weakness that could affect handling precision and safety if not addressed. The braking system is the primary area of concern due to a history of excessive corrosion on pipes, pitted discs, and fluctuating performance. The October 2025 failure for fluctuating front brakes and corroded pipes highlights that the hydraulic system is reaching the end of its effective service life. Additionally, the suspension history shows a pattern of failing components including fractured coil springs and perished ball joint dust covers. Any prospective buyer should budget for immediate overhaul of the suspension bushings and brake integrity to ensure the vehicle remains reliable for continued use.
