2016 DS DS4 1.2L Petrol · LR08 PAM

The latest MOT test result for the 2016 DS4 on 2025-09-09 was a pass, though it revealed a critical outstanding recall from Citroën requiring free repair for the offside front constant velocity (CV) joint boot failure, which was already confirmed as severely deteriorated in prior tests. The vehicle’s MOT history shows a pattern of recurring issues with the offside front CV joint boot, failing in 2023 and 2024 with split or insecure boots, and only passing in 2025 after the recall was addressed. While the 2025 test was clean aside from the recall advisory, the persistent failure of this component suggests either a fundamental design flaw in the joint boot design or potential substandard aftermarket replacement parts. Additionally, oil leaks from the engine and tyre wear approaching legal limits are recurring advisories, indicating underlying wear or potential fluid management issues that warrant further attention. The recorded mileage of 40,231 miles for a vehicle aged approximately ten years represents a relatively low annual usage rate of around 4,023 miles per year, which is unusual for a car of this age. Such low mileage often reflects periods of prolonged standing, particularly if the vehicle was used in a region with less traffic or was kept in a garage. However, this usage profile can mask significant internal wear, especially in components like the CV joints, suspension, and braking systems, which may have suffered from prolonged inactivity-induced corrosion or stiffness. The CV joint failures suggest that the joint itself may be prone to premature failure, even at relatively low mileage, potentially exacerbated by environmental exposure or poor maintenance practices during standstill periods. For a prospective buyer, the most critical inspection should focus on the CV joint assembly and surrounding drivetrain components. Visually inspect the offside front CV joint boot for signs of recent tears or fluid leaks, and check for excessive play or unusual noises when the vehicle is driven, particularly during cornering or acceleration. Listen for a grinding or clunking sound from the offside front wheel area, which may indicate binding or misalignment in the joint or adjacent suspension components. The recurring oil leak advisory suggests monitoring the engine oil level and checking for oil stains under the vehicle, as well as ensuring the oil filter and gaskets are in good condition. Additionally, verify the tyre condition beyond the legal limits noted in the MOT history; inspect for sidewall cracking or perishing, which can weaken tyre integrity over time, even at low mileage. Beyond the immediate defects, the DS4’s age and low mileage make it a candidate for thorough calendar-based maintenance checks. Given its age, the vehicle’s fluids—particularly the engine oil, brake fluid, and coolant—should be replaced according to manufacturer recommendations, even if mileage is low, as fluids degrade over time regardless of usage. Check the brake system for signs of corrosion on the discs or binding calipers, especially on the near-side front, where standing can accelerate rust formation. Inspect the suspension for signs of wear in bushes, coil springs, or struts, as prolonged inactivity can stiffen or crack these components. Finally, verify the battery health, as low usage can lead to a discharged or failing battery, and test the starter motor and electrical systems for responsiveness. A comprehensive inspection of the exhaust system for leaks or structural integrity is also advisable, given the potential for corrosion from standing.
