2017 Citroen C4 Grand Picasso 1.6L Diesel · H4 FET

The most recent MOT, carried out on 4 July 2026, was passed but recorded an advisory that the off‑side front tyre is worn close to the legal limit and shows edge wear. Earlier advisories in the last six years relate to the same tyre developing slight cracking and a rear brake disc that is pitted but not yet critically thinned. Apart from a headlamp lens product note in 2020, the remaining tests were clean, indicating that the vehicle has generally been maintained in a stable condition with only gradual wear appearing on high‑stress components rather than any sudden deterioration. With 48,269 miles logged on a 2017 model, the average annual distance is roughly 5,300 miles, well below the typical UK usage of 8‑10 000 miles per year. Such low mileage suggests the car has either been driven lightly or has spent extended periods stationary. Light use reduces wear on the engine, transmission, and suspension, but it also means that age‑related degradation—particularly tyre perishing, battery electrolyte loss and corrosion of seals—may be more pronounced than mileage‑driven wear would suggest. Prospective buyers should give the off‑side front tyre immediate attention; measure the tread depth (minimum legal is 1.6 mm) and inspect the sidewall for any cracking, bulging or dry‑rot, as the advisory indicates edge wear that can accelerate failure. A tyre that is close to the limit should be replaced promptly, and the remaining three tyres should be checked for age using the DOT code, with any tyre older than six years considered for replacement regardless of tread. The rear brake disc, flagged as pitted, should be measured for remaining thickness; if the scoring is extensive or the disc is within 1 mm of the minimum safe thickness, resurfacing or replacement will be required. During a test drive listen for any brake shudder, pulsation or uneven braking effort, which would confirm disc wear or caliper binding. Given the vehicle’s age and low mileage, a thorough visual inspection for time‑related issues is essential. Examine the under‑carriage, wheel arches and suspension mounting points for surface rust or corrosion, especially around the front sub‑frame and rear axle housings. Test the 12‑V battery with a load tester or have it checked at a garage, as batteries can lose capacity after several years of inactivity. Verify that engine oil, brake fluid and coolant have been replaced within the manufacturer’s calendar intervals; fluid samples should be clear and free of moisture or sludge. Finally, confirm that the service book contains regular oil changes and any recommended timing‑belt or chain service, as these are critical for long‑term reliability even on low‑kilometre cars.
