2002 Transporter T.4 2.5L Diesel · SJ02 AGL

The vehicle is currently roadworthy but the most recent inspection indicates a shift toward worsening mechanical condition after years of clean records. While the van passed without defects between 2020 and 2023, the January 2026 test at 83,008 miles revealed several newly emerged issues. The presence of a front oil leak, corrosion on both front brake pipes, and black smoke emissions suggests that the vehicle is beginning to show its age despite the low annual mileage. The mileage profile is exceptionally low for a 24-year-old Transporter, averaging approximately 3,400 miles per year. The data shows a significant period of inactivity between April 2022 and March 2023, where the vehicle covered only 53 miles in three years. This pattern of intermittent use often leads to degradation of rubber-based components and internal corrosion of fluid lines due to stagnation. The recent jump of 3,346 miles between 2023 and 2026 indicates a sudden increase in usage, which may be stressing the aforementioned aging components. A physical inspection must focus heavily on the braking system and engine integrity. The tester flagged corroded brake pipes covered in grease, which often indicates an attempt to hide surface rust or poor maintenance of the hydraulic lines. A buyer should verify the condition of the front discs, which were already pitted in 2019, and ensure the brake pipes are not structurally compromised. The black smoke reported in 2026 points to a rich-running condition or potentially failing injectors, requiring a professional diagnostic check to prevent further engine wear. The front oil leak requires close scrutiny to determine if it is a simple seal failure or a more significant gasket issue. Given the low mileage and age, the chassis and suspension mounting should also be inspected for structural corrosion that may not be captured in an MOT until it reaches a critical threshold. The transition from clean records to multiple advisories suggests the vehicle is now entering a phase where preventative maintenance is essential to avoid costly mechanical failures.
