2009 Mercedes-Benz CLK 3.5L Petrol · GY09 HME

A recurring theme of front‑brake wear, rear‑brake‑pipe corrosion and a historic front‑coil‑spring fracture defines the mechanical narrative of this 2009 Mercedes‑Benz CLK. The most recent MOT on 12 March 2026 recorded a pass but flagged thin nearside and offside front pads and corroded rear brake pipes, echoing similar pad‑wear advisories from 2025 and a pattern of rear‑pipe greasing noted each year. The only recorded failure was the 23 March 2021 near‑front coil‑spring break, which was rectified before the subsequent pass on 25 March 2021; since then the record shows only advisory items, suggesting no further major structural failures but a steady accumulation of wear‑related notes. At 91 070 miles over 17 years the vehicle averages roughly 5 350 miles per annum, well below typical UK usage for a car of this age. The MOT chronology shows annual testing without significant gaps, indicating the odometer reading is likely representative of actual use rather than prolonged storage. Low annual mileage can mean slower wear on major power‑train components, yet it also raises the possibility of long periods of inactivity, which can accelerate corrosion on brake lines and rubber components, as reflected in the repeated rear‑pipe advisories. Prospective buyers should concentrate on the braking system. Verify pad thickness on both front wheels and inspect the rear brake pipes for rust, pitting or grease accumulation that could conceal leaks; listen for any hissing or fluid seepage when the brakes are applied. During a road test, the pedal should feel firm with consistent travel; any sponginess, judder or a noticeable pull to one side may indicate deteriorating pads, pipe corrosion or uneven caliper function. Examine the front coil spring area for any unusual clunking over bumps, which could reveal an incomplete repair of the 2021 fracture. The suspension and wheel‑bearing advisories merit targeted checks. The off‑side front suspension arm pin or bush was noted as worn in 2023, so feel for looseness or knocking when steering over uneven surfaces and watch for any steering wheel vibration at higher speeds. Slight play was recorded on both front wheel bearings; a low‑frequency hum or grinding that changes with wheel speed can confirm bearing wear. Inspect the tyre sidewalls for the cuts reported in 2024 and 2023, ensuring the tread depth remains within legal limits and that no progression toward ply exposure is evident. Finally, be aware that full under‑tray covers have been present on several tests, potentially masking hidden defects; request removal of these trays for a thorough visual inspection of the chassis, exhaust and under‑body components before finalising any purchase.
