2009 Mercedes-Benz CLK 2.1L Diesel · J55 KAM

A remarkably clean DVSA history defines this 2009 Mercedes-Benz CLK, presenting a track record of roadworthiness unmarred by advisories or recorded defects across all five tests on file. Both failure entries from late 2023 and early 2026 returned no defect entries, suggesting both retests were abandoned or withdrawn before examiner findings were logged, or that the reasons for refusal were of a minor and rapidly rectified nature. The intervening passes at 2023-12-06, 2025-02-03, and most recently 2026-02-11 all cleared without a single advisory, which for a chassis of this vintage is a notably favourable indicator. With no recorded brake, suspension, exhaust, lighting, or corrosion findings throughout the entire history, the vehicle presents as one that has either been conscientiously maintained or has not yet developed the wear patterns typical of its age. At 74,082 miles over a seventeen-year lifespan, this CLK has averaged roughly 4,358 miles annually, a figure well below the typical mileage for a car of its age and class. This low accumulation rate points to either genuinely limited use as a secondary or leisure vehicle, or extended periods of inactivity between drives. Mechanically, low annual mileage on a Mercedes of this era carries specific implications rather than being an unqualified positive. Seals, gaskets, and flexible rubber components such as suspension bushes, anti-roll bar links, and engine mountings are susceptible to drying, perishing, and seizing when not exercised regularly, while brake discs and pads can develop lip corrosion and binding caliper behaviour from infrequent use. Coolant and brake fluid also degrade through age rather than mileage alone, and a vehicle that has covered fewer miles will nonetheless have absorbed the full seventeen years of fluid ageing. Conversely, the low figure means the major mechanical consumables such as the clutch, drivetrain, and major brake components are likely to have substantial remaining service life. For a prospective buyer conducting a physical inspection, the absence of recorded advisories means there is no specific flagged component to target, so attention should shift to the areas most likely to suffer on a low-mileage Mercedes of this generation. On a test drive, listen carefully for clonks or knocks from the front suspension over uneven surfaces, particularly indicative of perished top mounts, control arm bushes, or anti-roll bar drop links, all common failure points on the W209 chassis. Apply the brakes firmly from speed and check for any judder through the pedal, which would suggest lipped or corroded front discs, and verify that the vehicle pulls away cleanly without any grabbing or dragging sensation that could indicate binding caliper sliders. On a quiet stretch, release the steering at low speed to check for any pulling to one side, which can point to uneven corrosion on the brake discs or suspension component wear. Beneath the vehicle, inspect the rear subframe mounting areas, the front suspension lower arms, and the brake pipe runs for any surface corrosion, as even cars with clean MOT histories can develop localised rust in these zones between tests. Additional checks appropriate to a low-mileage example include a thorough inspection of all fluid levels and condition, with particular emphasis on the coolant, which on Mercedes vehicles of this era can degrade and contribute to cooling system component wear if not replaced on a time-based schedule. Inspect the undertray and engine sump area for any signs of historic weeping seals, as dried residue may indicate past leaks that have since sealed through disuse. Examine the condition of the tyres for any flat-spotting, sidewall cracking, or uneven shoulder wear, which on a vehicle that has stood for extended periods can compromise roadholding even with adequate tread depth. Finally, verify that the air conditioning system functions effectively, as refrigerant seals and compressor clutches on infrequently driven Mercedes vehicles frequently require attention, and ensure that the comprehensive service history is available to confirm that age-related maintenance items such as timing chains, coolant, and brake fluid have been addressed on schedule rather than solely by mileage.
