2015 Citroen C4 1.6L Diesel · PX65 NAE

The Citroën C4’s most recent MOT test on January 5, 2026, at 70,131 miles confirms it passed without defects, though the December 2025 test at 69,936 miles—just 195 miles earlier—was a failure with no recorded issues. This abrupt retest suggests either a genuine oversight in scheduling or a temporary administrative error, as no defects were logged. The preceding tests in August 2024 and August 2023 also passed cleanly, indicating no consistent mechanical failures. However, the lack of advisories across all tests means even minor wear—such as suspension bushes, coil springs, or brake caliper binding—has not been formally noted by the tester. While the vehicle has not shown recurring faults, the retest raises questions about whether routine maintenance has been overlooked between services. The recorded mileage of 70,131 miles over 11 years averages approximately 6,376 miles annually, which aligns with typical usage for a vehicle of this age. There are no extreme gaps or sudden spikes in mileage between tests, though the interval between the August 2023 and August 2024 tests—just 12 months—is unusually short for a car approaching its 10th anniversary. This could imply either proactive servicing or an attempt to avoid MOT failure, though the absence of advisories in prior tests suggests no urgent mechanical concerns. The most recent 195-mile gap between the December 2025 failure and January 2026 pass is anomalous and warrants clarification, as it does not reflect normal wear patterns. Given the clean MOT history, a buyer should prioritise a thorough inspection of high-wear components that often go unnoticed without advisories. Focus on the suspension system—particularly the rear bushings and coil springs—for excessive play or corrosion, as these are common points of failure in C4 models. The braking system should be checked for uneven disc wear, binding calipers, or corrosion in the brake lines, especially if the vehicle has seen wet or salted roads. Structural integrity is another critical area; inspect the wheel arches, sills, and subframe for signs of rust penetration or weakened sections, as these can compromise safety over time. While the MOT record shows no red flags, these elements are typically beyond the scope of a basic test and require hands-on examination.
