2009 Citroen C4 1.6L Diesel · YF58 ABK

A recurring theme across the MOT record is structural corrosion and safety‑critical component degradation, highlighted by the 2021‑12‑09 failure which listed an excessively corroded off‑side rear suspension mounting, severely weakened near‑side and off‑side front seat‑belt anchorages, and a fractured off‑side front coil spring, alongside a missing near‑side rear brake pad. These major defects have appeared alongside a series of recurring advisories for front brake disc surface wear, brake binding, and multiple lighting failures, indicating that the vehicle’s core safety systems have required repeated remedial attention rather than showing a clean, improving trend. With 97,420 mi recorded on a 2009 model, the average annual accumulation is roughly 5,700 mi, well below the typical UK usage for a vehicle of this age. The MOT history shows tests in consecutive years with both passes and fails, and a cluster of results in 2020 where a pass and a fail were recorded within days, suggesting periods of intermittent use or possibly short‑term repairs that were not fully resolved. Low mileage does not preclude the progression of rust on suspension mounting points or seat‑belt anchorages, especially if the car has spent extended periods stationary, so the mileage figure should be considered alongside the corrosion‑related failures rather than as an indicator of overall wear. Prospective buyers should concentrate on the suspension and chassis integrity first. Inspect the off‑side rear suspension mounting area for flaking rust, pitting, or compromised welds, and verify that there is no excessive play when the wheel is rocked laterally or when the vehicle is lifted. Examine both front seat‑belt anchor points for signs of corrosion, cracking, or weakened metal, and test the belt retraction for smooth operation. The fractured front coil spring recorded in 2020 warrants a visual check of the spring’s condition and an assessment of ride height symmetry; any uneven stance, clunking over bumps, or visible spring damage would confirm the need for replacement. The brake system also demands attention. Confirm that both rear brake pads are present and of even thickness, and probe the pedal for any sponginess, judder, or pull that could indicate lingering binding noted in earlier advisories. Inspect the front discs for deep scoring or excessive pitting beyond normal wear, and listen for squeal or grinding under braking. Finally, verify that all position lamps, stop lamps, and the registration‑plate lamp operate correctly, and ensure the trailer socket is securely mounted and electrically sound. A thorough mechanical inspection of these identified areas will reveal whether the vehicle’s safety‑critical systems have been adequately restored or if further remedial work is required before committing to purchase.
