2009 Citroen C4 1.6L Diesel · PJ59 LWN

Structural deformation to the nearside outer sill and persistent wear within the front suspension arm bushes define the primary mechanical narrative for this Citroen C4, which has otherwise maintained a consistent pass rate despite recurring minor defects. While the vehicle successfully passed its most recent MOT on 12 December 2024, the history reveals a pattern of intermittent failures related to basic lighting and interior safety components, alongside long-standing advisories regarding the vehicle's structural integrity and exhaust system. The record suggests a vehicle that requires ongoing monitoring of its chassis and suspension mounting points rather than one with a clean bill of health. Accumulating 89,882 miles over seventeen years results in an average of approximately 5,287 miles per annum, a figure that sits well below the typical usage profile for a vehicle of this age. This low-mileage trend, punctuated by consistent annual testing, indicates that the car has not been subjected to high-intensity motorway use but has instead experienced frequent short-distance cycles. Such usage patterns often accelerate the deterioration of exhaust systems due to moisture buildup and can lead to the stiffening of rubber suspension components, which aligns with the recurring advisories noted in the vehicle's history regarding suspension arm bushes and exhaust gas leaks. Prospective buyers should conduct a thorough physical inspection of the nearside outer sill, as the recurring advisory regarding structural deformation indicates potential past impact or corrosion damage that warrants professional assessment. During a test drive, pay close attention to the front end of the vehicle when navigating uneven road surfaces or speed humps; any audible knocking or clunking sounds, or a lack of steering precision, would suggest that the previously noted suspension arm bush wear has progressed beyond the advisory stage and now requires component replacement. Furthermore, the history of pitted and scored brake discs suggests that the braking system should be checked for pedal judder under moderate braking, as well as any signs of binding calipers that could cause the vehicle to pull to one side. The exhaust system also requires specific attention, given the repeated advisories for minor leaks between 2020 and 2023. Listen for any blowing or rasping noises when the engine is under load, as these leaks can often worsen over time and may eventually result in failure during an emissions test. Because the vehicle has experienced multiple lighting-related failures, ensure that all exterior lamps, including the dipped beams and registration plate lights, are fully functional. Finally, verify the condition of the brake pedal anti-slip provision, as the 2024 failure for its absence indicates a need to inspect the pedal rubbers for excessive wear, which can compromise driver safety in wet conditions.
