2021 Peugeot Boxer 435 PRO L3H2 Bluehdi 2.2L Diesel · PY71 AZR

A 2021 Peugeot Boxer 435 PRO L3H2 BlueHDi with only two MOT tests on file and a completely clean pass record at both appointments presents a very limited data set from which to draw mechanical conclusions. The most recent test on 18 December 2025 was issued with no advisories or defects recorded, following an equally clean pass on 9 December 2024. While the absence of recorded advisories across both tests is a positive indicator for the immediate inspection items covered under the MOT regime, it is worth noting that the vehicle only became eligible for testing on 1 December 2024, so the available history captures just the first year of mandatory testing rather than a long-term pattern. Without earlier data points, the trend is simply that the vehicle has passed every test it has undergone, but no longitudinal pattern of wear can yet be established from DVSA records alone. With 56,335 miles recorded on a five-year-old vehicle, the Boxer is accumulating approximately 11,267 miles per year, which sits broadly within the expected range for a commercial van of this type. This mileage profile suggests regular working use rather than periods of extended standing, which is mechanically beneficial for a diesel-powered vehicle of this class. Routine running helps to keep the diesel particulate filter active, maintains battery charge, and prevents the oil seals and rubber components typical of light commercial vehicles from drying out. The mileage is sufficient to have generated meaningful wear on consumable items such as brake pads, discs, tyres, and clutches, but it is not so high as to suggest imminent major mechanical intervention based on mileage alone. Given the clean MOT history, there are no specific components flagged by previous advisories that require targeted follow-up inspection during a viewing, but a prospective buyer should still focus on areas that commonly affect high-mileage Boxers. On a test drive, listen for any clonking or knocking from the front suspension over uneven surfaces, as the Boxer is known for wear in the lower suspension arms and anti-roll bar bushes. Check for uneven tyre wear, particularly on the front axle, which can indicate misalignment or worn suspension components. The steering should feel precise without vibration or pulling to one side under braking, and the clutch should engage smoothly without slipping under load, as dual-mass flywheel replacement on these BlueHDi units can be costly if neglected. Under-bonnet, the BlueHDi engine should be examined for any signs of oil leaks around the sump, cam cover, and turbo piping, and the coolant system should be checked for leaks at the known weak points around the EGR cooler and thermostat housing. Inspect the underside for any corrosion on the brake lines, fuel lines, and subframe, particularly given that light commercial vehicles often operate in environments where road salt accelerates chassis corrosion. The AdBlue system and diesel particulate filter should be confirmed as functioning without warning lights illuminated, as repairs in these emissions components can be expensive. Finally, verify that the timing belt or cambelt replacement interval has been observed according to Peugeot's service schedule, as neglect of this item on a high-mileage diesel can result in catastrophic engine damage.
