2020 Citroen C5 1.5L Diesel · ML20 VCM

A pattern of recurring brake wear advisories, tyre edge wear, and a single dangerous brake pad failure defines the mechanical profile of this 2020 Citroen C5 across its MOT history. The most recent test on 2026-07-08 resulted in a pass after an immediate retest following a failure for an offside front headlamp aim being too low, alongside a minor defect for an inoperative nearside registration plate lamp. Both front inner tyres were also flagged as advisory for being worn close to the legal limit on the inner edge. Looking back across the four recorded tests, brake-related advisories appear in three of them, with the 2024 test recording an offside rear outer brake pad less than 1.5 mm thick which was categorised as dangerous, requiring immediate rectification before the vehicle could be re-presented. Tyre wear on the inner or outer edges has also been flagged in three separate tests, and the 2025 test recorded a perished offside rear tyre on top of edge wear. While the vehicle has ultimately passed each annual assessment and the most recent outcome is a pass, the consistent recurrence of brake and tyre deterioration suggests that consumables on this chassis are being worked hard. At 58,480 miles over six years, the annual mileage accumulation of roughly 9,747 miles per year is broadly typical for a vehicle of this age, neither unusually low nor particularly high. There are no prolonged gaps between tests that would suggest extended periods off the road, with annual examinations recorded from 2023 through to mid-2026, which indicates reasonably consistent use. This level of usage is sufficient to keep mechanical components in regular operation, reducing risks associated with long-term standing such as seized brakes or dried seals, but it is also enough mileage to generate the kind of progressive wear seen in the MOT record. The combined effect of moderate annual mileage and the recurring brake and tyre advisories points to a vehicle that is being driven regularly but where consumable replacement appears to be occurring reactively rather than preventively. For a prospective buyer, the brake system warrants the closest physical inspection given its repeated appearance in the MOT record. The dangerous offside rear brake pad finding from 2024 means the caliper, slider pins, and rear brake disc on that side should be checked for binding or uneven wear, and the rear discs flagged as corroded and pitted in 2025 should be inspected for lipping and scored surfaces that could produce pedal judder under heavy braking. Listen for any scraping or grinding noise from the rear corners on a test drive, and verify that the handbrake holds firmly on an incline, as pitted rear discs often correlate with reduced handbrake efficiency. The front brake pads were also noted as wearing thin in 2024, so the front caliper condition and pad thickness should be confirmed, with attention to whether the vehicle pulls to one side under braking which could indicate a seized slider or contaminated friction material. The tyre wear pattern flagged across multiple tests, specifically inner edge wear on the front pair in 2026 and the nearside front in 2025, alongside the offside rear edge wear and perish recorded in 2024 and 2025, is consistent with either incorrect wheel alignment, worn suspension components, or a combination of both. On a test drive, the vehicle should be evaluated over uneven road surfaces for any knocking, clonking, or excess vertical travel from the front suspension, and particular attention paid to the condition of the lower wishbones, suspension bushes, and anti-roll bar drop links which are known wear items on Citroen chassis. Any steering pull, vagueness off-centre, or uneven steering effort when cornering would warrant further investigation into the front geometry. Finally, the persistent registration plate lamp minor defects recorded in both the 2025 and 2026 tests suggest an intermittent electrical issue with the lamp holder or wiring that should be checked, and the 2025 advisory of exhaust emissions being too clean to register, while not a cause for concern on a modern petrol or diesel, should be noted alongside confirmation that no dashboard warning lights are illuminated.
