2015 Citroen C4 1.2L Petrol · CK15 XGZ

The Citroen C4 presents a stable but imperfect maintenance profile as of its most recent MOT on 11 June 2025 at 85,939 miles. That initial test failed on multiple lighting defects and a worn nearside front suspension arm ball joint, yet the retest passed on the same day at the identical mileage, indicating the faults were addressed promptly. The 2024 cycle followed the same pattern, a failure for lighting defects and a headlamp fault rectified within the same session. This suggests the owner reacts to MOT failures rather than proactively maintaining the vehicle between tests. The trend is neither clearly worsening nor improving, but the repeated reliance on same-day retests points to a reactive rather than preventative approach to upkeep. The mileage progression tells a consistent story. Between the June 2023 pass at 76,910 miles and the June 2024 test at 81,194 miles, the car covered 4,284 miles in twelve months. The following year it added just 4,745 miles to reach 85,939 by June 2025. Annual distances of roughly 4,300 to 4,700 miles sit well below the typical 7,800-mile annual average implied by the car's age. This is low-mileage use for an eleven-year-old vehicle, which can mean fewer consumable replacements but also raises the possibility of long periods standing idle, a condition that can accelerate rubber deterioration and brake corrosion. The recurring theme across the MOT record is electrical, specifically rear and registration plate lighting. Failures appeared in both 2024 and 2025, affecting stop lamps, position lamps, and the number plate lamp. While these are minor defects, their repetition hints at a wiring, grounding, or switch issue that may not have been fully resolved. A buyer should inspect the rear light clusters, loom connections, and boot wiring for corrosion or chafing, particularly where the harness passes through the tailgate hinge area, a known weak point on Citroen C4 models. The nearside front suspension arm ball joint flagged in the 2025 test is the most mechanically significant finding. Although the advisory noted only slight play and the retest passed, any play in a ball joint indicates wear that will progress. A buyer should have the front suspension and steering joints physically loaded and inspected, checking for deterioration in the track rod ends and wishbone bushes. At nearly 86,000 miles, the dampers, coil springs, and top mounts deserve close scrutiny for leaks, sag, or cracking, especially given the car's age and the likelihood of original suspension components still being in place.
