2018 Citroen Unknown 2.0L Diesel · SP18 AHX

The vehicle remains roadworthy, though the maintenance trend shows a shift from previously clean records to emerging mechanical concerns. The most recent test in March 2026 at 35,371 miles passed despite a recorded non-excessive oil leak and an active TPMS warning light. While these issues did not cause a failure, the appearance of an oil leak suggests the vehicle is beginning to show signs of age-related seal or gasket degradation that were not present in earlier inspections. The mileage profile is consistently low for an eight-year-old vehicle, averaging approximately 4,400 miles per year. Between February 2022 and February 2024, the car covered only 10,908 miles, indicating very light usage. However, there was a noticeable increase in usage between February 2024 and March 2026, where the vehicle clocked 12,560 miles in just two years. This uptick in activity correlates with the first instances of significant wear on the braking system noted in the February 2025 test. A buyer must scrutinise the braking system, as the February 2025 test at 29,280 miles flagged thin front brake pads and pitted or scored discs on both front wheels. These issues often occur on low-mileage cars that sit for long periods, allowing corrosion to form on metal surfaces. The oil leak identified in the 2026 test requires a physical inspection to determine if it originates from a simple cover gasket or a more critical engine component. Additionally, the active TPMS light should be diagnosed to ensure it is merely a faulty sensor rather than a slow pressure leak in one of the tyres.
