2011 Citroen C4 1.6L Diesel · HN11 AAZ

The Citroën C4’s most recent MOT test on 2025-05-09 at 143,165 miles passed without defects, confirming current roadworthiness. However, the history reveals an inconsistent pattern: two consecutive failures at 129,762 miles in April 2023, followed by a clean pass just days later at the same mileage, suggests either a temporary oversight or a minor, easily corrected issue. The subsequent tests in early 2024—another failure at 137,257 miles followed by a pass at 137,258 miles—implies a similar pattern of quick resolution. While no recurring major faults are logged, the repeated failures at identical mileages warrant scrutiny of components prone to sudden failure, such as brake systems or suspension linkages, which might have been addressed between tests. The recorded mileage of 143,165 miles over 15 years averages approximately 9,544 miles annually, a rate consistent with typical light-to-moderate usage. There are no extended gaps between tests beyond the standard 12-month interval, though the back-to-back failures at 129,762 and 137,258 miles indicate either rushed repairs or a brief period where maintenance lapses occurred. The absence of advisories or partial passes suggests no ongoing, unresolved issues were carried over between tests, but the repeated failures at nearly identical mileages could imply a recurring mechanical quirk, such as a brake caliper binding or a suspension bush failing at a predictable wear threshold. Given this history, a prospective buyer should prioritise an in-person inspection of the brake system, particularly the rear calipers and discs, which are often flagged in such patterns. The repeated failures at similar mileages may indicate wear in suspension components—check rear bushes, coil springs, and track rods for excessive play or corrosion. Exhaust emissions should also be monitored, as minor leaks can sometimes go unnoticed until test day. While the vehicle has passed its most recent MOT, the history hints at potential areas of deferred maintenance, so verifying service records for brake fluid changes, suspension servicing, and rust treatment—especially around wheel arches and sills—would be prudent. The lack of advisories is reassuring, but the mechanical inconsistencies demand thorough verification.
