2004 Mercedes CLK 1.8L Petrol · MB04 JOU

The current roadworthiness of this Mercedes CLK is poor, following a significant and concerning decline in mechanical maintenance standards. While the vehicle held a clean record in 2023, the most recent test in April 2026 resulted in critical failures across engine, safety, and suspension systems. The transition from a pass to a comprehensive failure involving major exhaust leaks and electronic stability faults indicates that the vehicle requires immediate and extensive mechanical attention to be road legal again. At 22 years old, the recorded mileage of 173,293 miles averages to approximately 7,877 miles per year, which is consistent with typical usage for a luxury coupe. However, there is a notable increase in activity with nearly 17,000 miles covered between April 2024 and April 2026. This period of use, combined with the vehicle's age, appears to have accelerated the wear on aging components, leading to the rapid succession of mechanical deplet seen in the recent history. A prospective buyer must conduct a thorough physical inspection of the front suspension, as the history shows recurring issues with fractured coil springs, worn track rod ends, and insecure anti-roll bar linkages. The recent failure of the nearside front wheel bearing with excessive play suggests that the entire hub and steering assembly may be nearing the end. Furthermore, the braking system requires close scrutiny given the repeated warnings regarding thin pads, pitted discs, and a parking brake that now falls below efficiency requirements. The engine and emissions systems also present significant risks due to the inoperative check engine light, failed lambda readings, and major exhaust leaks. These faults suggest deeper electronic or sensor issues that could be costly to diagnose. Before purchasing, a buyer should verify the structural integrity of the chassis and ensure that the neglect indicated by the recent mechanical failures has not masked underlying rust or deeper drivetrain damage.
