2003 Mercedes-Benz CLK 2.7L Diesel · OO03 ACG

The vehicle is currently roadworthy, having passed its latest MOT on 8 July 2026 at 60,908 miles. However, the maintenance trend shows a reactive pattern where significant faults are only addressed after a failure. The recent failure in April 2026 is particularly concerning, as the engine failed the test due to excessive black smoke emissions and an inoperative engine malfunction light. This follows a period of instability in early 2025 where the car failed for missing wheel bolts, a fractured coil spring, and worn track rod ends. The mileage profile is exceptionally low for a 23-year-old vehicle, averaging approximately 2,650 miles per year. There are long intervals between tests, such as the two-year gap between October 2022 and April 2024. While low mileage generally reduces wear on the drivetrain and engine, it often leads to the degradation of rubber components and fluid systems due to inactivity. The record shows the car has covered only 4,050 miles between April 2025 and July 2026. A physical inspection must focus on the suspension and braking systems, which show a history of recurring issues. The record repeatedly notes worn front suspension arm bushes and wheel bearing play dating back to 2017, 2018, and 2021. Corrosion on the rear brake pipes was noted in both 2016 and 2018, requiring a thorough check for structural integrity of the hydraulic lines. Given the recent emissions failure for black smoke, the buyer should verify the fuel system and turbo health to ensure the lean or rich condition has been properly rectified beyond a simple sensor reset.
