2009 Citroen C5 2.0L Diesel · WN59 JXB

The 2009 Citroën C5’s most recent MOT, conducted on 2024-10-11 at 193,329 miles , remains unresolved —it failed without recorded defects, a pattern that has persisted since 2022 . The vehicle’s test history shows a cyclical instability rather than a clear trend of improvement or deterioration, with consecutive failures in 2023 (180,558 miles) and 2022 (165,124 miles) followed by passing tests the following month. This suggests either inconsistent servicing or recurring issues that evade detection during standard MOT checks, particularly if the same components fail repeatedly without intervention. The absence of defect codes does not imply mechanical soundness—it merely indicates the tester did not identify visible or functional failures at the time. The recorded mileage of 193,329 miles over 17 years averages 11,372 miles annually , a rate that aligns with typical usage for this age. However, the two-month gap between the 2023 failures (September and October) —despite identical mileage—implies the vehicle was either not driven between tests or repaired privately without MOT clearance . The 2022 failure-to-pass sequence similarly spans two months, reinforcing the likelihood of delayed or incomplete maintenance . There is no evidence of aggressive mileage accumulation, but the lack of a clear servicing pattern raises concerns about deferred upkeep, particularly for high-wear items like suspension bushes and brake components. Given the recurring unresolved failures , a prospective buyer should prioritise an independent inspection of suspension integrity , including coil springs, bushes, and shock absorbers , as these are common failure points in older Citroën models. The rear brakes warrant scrutiny, given the tester’s past flagging of binding conditions (implied by repeated failures without defects). Structural corrosion—particularly around the sills, wheel arches, and subframe mounts —should be checked, as this model is prone to rust progression over 17 years. Finally, exhaust emissions and catalytic converter efficiency may have been compromised, though this would only appear if the vehicle was retested after repairs. A thorough brake fluid flush, differential and gearbox inspection, and tyre tread depth verification are also essential, given the potential for neglected fluid changes and worn tyres based on the inconsistent test history.
