2009 Mercedes-Benz CLK 2.0L Petrol · HG09 YLF

The 2009 Mercedes-Benz CLK presents a stable mechanical trend, culminating in a clean pass on 14 August 2025 at 171,301 miles with zero defects recorded. The preceding test on 13 August 2025 shows a failure at the identical mileage, yet notably, no defects were recorded for this failure either. This indicates an administrative anomaly rather than a sudden mechanical breakdown, as the vehicle passed the following day without any recorded repairs or advisories. The maintenance trend remains consistently stable, demonstrating no recurring mechanical faults across the documented history. The mileage accumulation aligns precisely with typical annual usage for a vehicle of this age. Between the August 2023 test at 151,379 miles and the August 2024 test at 161,749 miles, the CLK covered 10,370 miles. The subsequent year saw a near-identical accumulation of 9,552 miles, reaching 171,301 miles by August 2025. This steady, consistent progression rules out prolonged periods of standing or sudden high-mileage surges, suggesting regular, predictable use that keeps lubricants circulating and components exercised. Despite the absence of recorded defects, a 17-year-old CLK with 171,000 miles demands a rigorous physical inspection focused on structural integrity and age-related deterioration. Buyers should thoroughly examine the subframes, sills, and suspension mounting points for corrosion, a common issue on vehicles of this vintage. The condition of the suspension bushes, coil springs, and shock absorbers requires close scrutiny, as high-mileage wear often manifests as cracking or settling before triggering an MOT failure. Brake disc thickness and caliper operation also warrant verification, alongside a detailed check of the exhaust system for leaks or catalytic converter efficiency, ensuring the powertrain remains compliant and mechanically sound.
