2016 Citroen C3 Picasso 1.2L Petrol · GV66 OAB

A rear brake failure on the most recent test defines the mechanical story of this C3 Picasso. On 17 April 2026 the vehicle passed with no defects recorded, but that pass came immediately after a failure on 16 April 2026 in which the offside rear brake pads were measured at less than 1.5 mm and classified as Dangerous, alongside a Major defect for a significantly and obviously worn offside rear brake disc. The nearside rear pads were also flagged as wearing thin at the same test. The pattern through the MOT record is otherwise one of clean passes from 2019 through 2022, followed by a gradual emergence of wear-related items in 2024 and 2025, including front suspension ball joint play and dust cover deterioration, a slightly distorted offside front road wheel, and minor cuts and damage to the offside rear tyre. The 2026 failure therefore represents an escalation from advisory-level wear into a genuine safety defect, and any prospective buyer should treat the rear braking system as the foremost area requiring verification rather than relying on the subsequent pass certificate alone. The recorded mileage of 44,688 miles over a ten-year span equates to roughly 4,469 miles per year, which is notably low for the age and platform. MOT testing has been consistent on an annual basis from December 2019 through April 2026, with no multi-year gaps that would suggest extended standing-off-road periods, so the low accumulation appears to reflect genuinely light use rather than dormancy. From a mechanical standpoint, low annual mileage on a vehicle of this type typically reduces wear on drivetrain components and can prolong the life of interior and bodywork items, but it does increase the likelihood of dried-out suspension and driveline rubber, stale brake fluid, and corrosion where moisture settles on infrequently used components. The fact that the brake discs and pads were allowed to reach a Dangerous state despite this low usage is worth weighing carefully, as it suggests those particular components were either neglected over a long interval or suffered from corrosion pitting through underuse rather than frictional wear. For a physical inspection, attention should focus first on the rear braking system. Even though the vehicle subsequently passed, the offside rear disc was recorded as significantly worn, and replacement should be confirmed rather than assumed. On a test drive, listen for any scraping or grinding noise from the rear wheels on light braking, check for pulling to one side under firm stops, and feel for judder through the brake pedal which can indicate remaining disc run-out or corrosion. The nearside rear pads were also noted as thin and should be inspected for remaining friction material. Beyond the brakes, the 2024 advisory for slight play in the nearside front suspension arm ball joint warrants a road test over uneven surfaces; listen for clonking or knocking from the front end on speed humps and directional changes, and have the joint checked for any worsening play as it can progress from advisory to failure within a test cycle. The deteriorated offside front ball joint dust cover recorded as a Minor in 2024 should also be inspected to confirm whether it has since split fully, which would allow contamination and accelerate joint wear. The remaining advisories are comparatively minor but worth verifying on inspection. The offside front road wheel was noted as slightly distorted in 2025, which on a driven test would typically present as a vibration through the steering wheel at higher speeds; the wheel should be checked for any worsening buckle or crack around the rim. The offside rear tyre has appeared in three consecutive tests with minor cuts or inner wall damage, suggesting either repeated kerbing or a persistent issue with tyre choice or alignment, and the current tyres should be examined closely for sidewall integrity and tread depth. Finally, the minor offside windscreen damage recorded in 2025 is unlikely to be a structural concern but should be confirmed as remaining outside the driver's swept area. Overall, this vehicle presents a mixed record in which most components are stable, but the rear braking episode and the front suspension advisories form the core of any pre-purchase assessment.
