2004 Peugeot Boxer 2.0L Diesel · D19 KAF

Corrosion management is the primary mechanical concern for this Peugeot Boxer, specifically regarding the vehicle's structural integrity and exhaust system. While the most recent test on 12 January 2026 resulted in a pass with no defects, the history shows a recurring pattern of oxidation on critical areas. Previous inspections flagged corrosion on the central silencer and the front coil spring, alongside more significant concerns regarding the offside front upper vehicle structure and inner arch. Although the 2025 advisory noted that the offside front outer sill corrosion was not structural, the presence of these multiple corrosion points across the chassis and bodywork suggests a vehicle that requires close monitoring to ensure surface oxidation does not progress into structural failure. The recorded mileage of 61,219 miles is exceptionally low for a 22-year-old commercial vehicle, averaging approximately 2,783 miles per year. This usage profile indicates the vehicle has spent significant periods stationary or has been used only for very light, intermittent duties. Mechanically, while this low mileage suggests minimal wear on the engine, gearbox, and drivetrain, it also increases the risk of age-related degradation. Long periods of inactivity can lead to the drying out of rubber seals, perished suspension bushes, and the development of surface rust on brake discs and exhaust components, which aligns with the corrosion issues noted in the MOT history. A prospective buyer should pay close attention to the chassis and bodywork during a physical inspection, specifically looking for any signs of bubbling paint or advancing rust around the previously flagged offside front inner arch and outer sill. On a test drive, listen carefully for any metallic clunking or knocking sounds when traversing uneven surfaces, which could indicate that the previously corroded front coil spring or associated suspension components have developed play. Additionally, pay attention to the exhaust note; any unusual droning or increased vibration might suggest that the corrosion on the central silencer has progressed to the point of affecting exhaust flow or mounting stability. Further scrutiny should be applied to the steering and suspension response to ensure that the low mileage has not resulted in seized components or perished rubber elements. Check for any pulling to one side or steering heaviness, which could stem from the structural corrosion areas affecting suspension geometry. Given the history of an insecure battery carrier, ensure the battery is firmly seated and the mounting hardware is intact to prevent electrical issues or physical damage during transit. The transition from a failure in early 2023 to a clean pass in 2026 suggests a period of maintenance, but the underlying tendency for corrosion remains the defining characteristic of this vehicle's long-term roadworthiness.
