2010 Citroen Relay 2.2L Diesel · SL10 PZE

The Citroën Relay’s most recent MOT test on 2024-05-16 resulted in a failure, though no defects were formally recorded—an anomaly in itself, as failures typically stem from specific mechanical or safety issues. The preceding tests from 2023 show a repeated pattern: two consecutive failures at 144,196 and 144,199 miles, followed by a pass at 144,199 miles just days later, suggesting either a retest or a minor oversight in the initial assessment. The trend since 2022 remains stable, with no recurring advisories or defects beyond the unexplained 2024 failure. This lack of documented faults does not equate to reliability, however, as the absence of recorded issues could imply either diligent maintenance or a failure to address underlying problems. The vehicle’s mileage progression of roughly 9,464 miles annually aligns with typical usage for its age, though the gap between the 2023 and 2024 tests—just under 7,200 miles—is unusually short for a car of this vintage. The rapid accumulation between 2021 (131,344 miles) and 2022 (138,131 miles) suggests either intensive use or a period of consistent driving, which may have accelerated wear on suspension components, brake systems, or drivetrain elements. The lack of advisories in prior tests does not preclude significant hidden deterioration, particularly in areas like coil springs, suspension bushes, or brake caliper binding, which often develop without immediate MOT failure. Given the absence of documented defects, a buyer should prioritise a thorough inspection of the suspension geometry, particularly the rear coil springs and bushes, which are prone to fatigue at this mileage. The brakes warrant close examination for uneven wear, binding calipers, or corrosion on the rear discs—common issues in older vehicles that may not trigger an MOT failure until they become severe. Structural integrity should also be assessed, focusing on the wheel arches, sills, and subframe for signs of corrosion, as rust can compromise the vehicle’s load-bearing capacity. The 2024 failure without recorded issues is particularly concerning; if no explanation is provided, it may indicate a test centre error or an unresolved mechanical concern that could resurface.
