2015 Citroen C4 1.6L Diesel · THZ 5012

Recurring structural failures within the rear suspension system define the mechanical history of this Citroen C4, which passed its most recent MOT on 18 April 2026 only after rectifying major fractures to both rear coil springs. This pattern of failure is significant, as the vehicle required identical repairs for the same rear coil spring fractures in May 2025, indicating either a recurring fatigue issue or the installation of components that failed to withstand standard road use. While the current status is a pass, the persistent advisory regarding wear in the rear axle swivel pins and bushes suggests that the rear suspension geometry remains a primary area of concern that has not yet been fully resolved. With a recorded total of 49,879 miles over an eleven-year lifespan, the vehicle averages approximately 4,534 miles per annum, placing it well below the national average for a car of this age. While this low usage might suggest limited exposure to high-speed motorway wear, the repeated suspension failures indicate that the vehicle has likely been subjected to harsh road conditions or heavy loading that the rear components were unable to accommodate. Prospective buyers should note that low-mileage vehicles that sit for extended periods can experience accelerated degradation of rubber components and seals, which may explain the ongoing issues with the rear axle bushes and the previous front shock absorber damping advisories recorded in 2022. During your test drive, focus your attention on the rear of the vehicle when traversing uneven road surfaces or speed humps. Listen specifically for any metallic clunking, knocking, or creaking sounds emanating from the rear wheel arches, as these are primary indicators that the rear axle swivel pins and bushes have reached the end of their service life. If the vehicle feels unsettled or bounces excessively after hitting a bump, it suggests that the rear suspension is failing to dampen movement correctly, potentially pointing to further issues with the recently replaced coil springs or the surrounding mounting points. Beyond the rear suspension, ensure the dashboard instrumentation is fully functional, particularly the tyre pressure monitoring system and the supplementary restraint system, both of which were flagged as faulty during the 2025 testing cycle. Verify that all warning lights illuminate upon ignition and extinguish once the engine is running, as any lingering faults in these electronic systems can indicate deeper wiring or sensor issues. Furthermore, pay close attention to the front end for any signs of steering pull or uneven tyre wear, as the reduced damping effect previously noted in the front shock absorbers could lead to compromised handling and premature wear on other steering components if those units have not been addressed since the 2022 inspection.
