2001 Peugeot Boxer 1.9L Diesel · DK51 AUM

The vehicle presents an improving maintenance trend regarding its structural integrity, following a period of significant deterioration. The most recent test on 7 October 2025 at 74,131 miles passed with a note that the body was freshly undersealed. This follows a critical failure in May 2023, where the tester flagged extensive corrosion across both inner and outer sills, inner arches, and suspension component mountings. The transition from those severe structural defects to clean passes in April and October 2025 suggests that major remedial work was undertaken to address the previous corrosion issues. The mileage pattern indicates very light use for a 25-year-old vehicle, averaging approximately 2,965 miles per year. The recorded mileage has progressed steadily from 58,472 miles in June 2015 to 74,131 miles in October 2025. While low mileage generally reduces drivetrain wear, the long intervals between significant mileage increases, such as the gap between 2017 and 2019, often correlate with vehicles being stored for extended periods. This period of inactivity can contribute to the perishing of rubber components and the development of corrosion, both of which appear in the historical record. A prospective buyer must conduct a thorough physical inspection of the chassis and sills to ensure the recent undersealing has effectively halted the progressive corrosion seen in earlier years. The 2023 failure highlighted significant rot in the offside front and nearside rear structural areas, so the integrity of these specific mounting points must be verified. Although the recent tests show no active defects, the history of corroded brake pipes and suspension mountings warrants a close examination of the entire braking system and all suspension-to-chassis connections. The recurring issues with tyre perishing and brake pipe corrosion suggest that while the vehicle is mechanically functional, it is susceptible to environmental degradation due to low usage. Inspect the condition of all rubber seals, hoses, and tyres for signs of age-related cracking. Particular attention should be paid to the underside to confirm that the recent undersealing is a permanent repair rather than a cosmetic mask for ongoing structural decay.
