2009 Citroen Grand C4 Picasso 1.6L Diesel · BN59 XTP

Recurring issues with braking components and a developing oil leak define the mechanical profile of this Citroen Grand C4 Picasso, as evidenced by the most recent MOT pass on 09 September 2025. The vehicle has demonstrated a persistent pattern of advisories regarding front brake disc wear and pitting, alongside a history of brake pad thinning that led to a dangerous failure in September 2024. While the recent test shows the vehicle is roadworthy, the presence of an oil leak and damaged seat belt webbing indicates that several mechanical and safety-related items remain flagged for attention. The recorded mileage of 99,587 miles over a 17-year period represents a relatively low annual accumulation of approximately 5,858 miles. While this lower usage rate often implies less frequent drivetrain wear, it can also mean components like seals and gaskets are subject to different stresses, such as those associated with shorter journeys or longer periods of inactivity. In this specific case, the low mileage has not prevented the emergence of recurring advisory items, particularly regarding the braking system and external fittings. A physical inspection during a test drive should focus heavily on the braking system and the reported oil leak. Given the repeated advisories for pitted and scored front brake discs, as well as the history of thin brake pads, listen for any squealing or grinding noises during deceleration and check for any pulsation or judder through the brake pedal, which can indicate uneven disc wear. The advisory for an oil leak, though noted as not excessive in the 2025 test, requires careful observation of the engine bay and underbody for fresh seepage, as persistent leaks can lead to more significant issues if left unaddressed. Additional attention should be paid to the nearside front tyre, which was recorded as being worn close to the legal limit or worn on the edge in the latest test. Check for any uneven tread wear, which could suggest underlying suspension or alignment issues. Furthermore, the damaged nearside front seat belt webbing noted in the 2025 advisory is a safety concern that should be inspected for fraying or weakness. Finally, verify the operation of the registration plate lamp and the condition of the nearside non-obligatory mirror to ensure all minor electrical and external component defects identified in previous tests have been rectified.
