2016 Citroen C3 Picasso 1.6L Diesel · TY04 JOS

The most recent MOT test on the 2016 Citroën C3 Picasso occurred on 2025-10-24 and resulted in a passing outcome, following a previous failure in the same month for exhaust-related issues. Despite this passing, the vehicle’s MOT history contains a pattern of recurring advisories and past failures that suggest underlying wear and potential long-term concerns. The front exhaust system has been a persistent problem, with a major leak to the diesel particulate filter (DPF) recorded in 2025, alongside repeated exhaust emissions failures in 2022 and 2025, indicating either a failing exhaust manifold, gasket, or a compromised flex joint. The rear exhaust mounting was also deemed defective in 2022, which could contribute to vibrations, noise, or emissions-related failures. While the advisories on brake discs—both front and rear—are not critical for roadworthiness, their consistent presence over multiple MOTs suggests progressive wear, particularly on the offside rear disc, which was noted as corroded. This may indicate prolonged exposure to moisture or standing, leading to rust formation, which can compromise braking performance if not addressed. The vehicle’s recorded mileage of 54,544 miles over approximately ten years represents an annual usage rate of around 5,454 miles, which is unusually low for a ten-year-old car. Such low mileage often correlates with periods of prolonged standing, particularly if the vehicle was used in a climate with high humidity or frequent exposure to moisture, as suggested by the corrosion on the rear brake disc. Low mileage can mask wear on consumables like brake pads, which were noted as thin in 2023, and may have been replaced before the vehicle accumulated sufficient miles to show significant wear. However, the absence of higher mileage could also imply that the vehicle was driven lightly, which might have delayed the onset of wear on suspension components, drivetrain elements, or fluid degradation. The stability of the mileage over the years suggests no sudden acceleration in usage, but the low figures warrant careful inspection for signs of standing-related corrosion or fluid degradation, as these can accelerate without regular movement. For the prospective buyer, the most critical areas to inspect are the exhaust system and braking components, given the recurring advisories and past failures. Start with the exhaust, particularly the front manifold and flex joints, as the major leak to the DPF and emissions failures indicate a compromised seal or structural integrity. Listen for unusual noises during acceleration or idling, such as rattling or hissing from the exhaust, which may signal a failing joint or manifold. The rear exhaust mounting should also be checked for loose connections or excessive vibration, which could exacerbate emissions issues. Regarding brakes, visually inspect the discs for further pitting, warping, or signs of rust, especially on the offside rear disc, which was already corroded. Listen for a grinding noise when braking, which could indicate thin pads or worn discs, and check for uneven brake pad wear or a binding caliper. If the pads are thin, they should be replaced promptly to prevent damage to the discs. Additionally, the vehicle’s low mileage profile makes it prudent to verify the condition of the brake fluid, as standing fluid can absorb moisture and lead to corrosion in the brake master cylinder or calipers. Beyond the mechanical checks, the buyer should conduct a thorough inspection of the vehicle’s structural integrity and fluid condition, as low mileage can sometimes obscure age-related wear. Begin with the tyres, checking for sidewall cracking or perishing, which is more common in older vehicles due to exposure to UV light and ozone over time. Ensure the tread depth is legal and that the tyres are evenly worn, as uneven wear may indicate suspension or alignment issues. Next, examine the suspension for signs of wear, such as bulging or cracked coil springs, worn suspension bushes, or excessive play in the struts. Clunking noises from the suspension during cornering or over bumps are typical signs of failing bushes or mounts. The 12V battery should be tested for charge capacity and terminal corrosion, as prolonged standing can lead to a weak or dead battery. Finally, the vehicle’s service history should be reviewed, particularly for fluid servicing, as fluids like brake fluid, differential fluid, and coolant degrade over time regardless of mileage. Given the age of the vehicle, the coolant should be replaced if it has not been serviced within the manufacturer’s recommended interval, typically every two years or 60,000 miles. If the service book is unavailable, a professional inspection to verify fluid condition and replace any degraded fluids is essential.
