2021 Peugeot Boxer 2.2L Diesel · KN21 ACU

The latest MOT test for the 2021 Peugeot Boxer on 2025-10-24 resulted in a passing grade, though it was accompanied by several recurring advisories that indicate ongoing but manageable issues. The vehicle’s MOT history shows a pattern of consistent minor failures and advisories, particularly around oil leaks, power steering seepage, and suspension component wear, with no major failures or dangerous defects between tests. The fact that the vehicle passed the latest MOT despite these advisories suggests that the issues are either well-contained or within acceptable operational limits, though the buyer should be aware of their persistence and potential long-term implications. The absence of a failed test in the last year indicates a stable maintenance trend, though the advisories warrant closer attention to prevent escalation into more serious defects. The recorded mileage of 41,833 miles for a 2021 model represents a moderate annual usage rate of approximately 8,367 miles per year, which is within the expected range for this age group. This level of mileage is neither exceptionally high nor low for a vehicle of this age, though it does not rule out potential wear from periods of prolonged inactivity, which can accelerate corrosion and fluid degradation. For instance, standing for extended periods may lead to brake disc corrosion or caliper binding, particularly if the vehicle was left in a damp or humid environment. Conversely, lower-than-average mileage could suggest less aggressive driving or infrequent use, which might have contributed to the observed advisories, such as minor suspension wear or power steering component deterioration, as these issues can sometimes develop more slowly in vehicles that are not driven frequently. Given the recurring advisories—particularly the oil leaks, power steering seepage, and suspension arm bush wear—the buyer should conduct a thorough mechanical inspection to assess the severity and progression of these issues. On a test drive, listen for unusual noises such as clunks or rattles in the suspension, especially when driving over bumps or at speed, which may indicate worn suspension components or loose bushings. Check for any oil leaks under the vehicle, particularly around the oil pan, oil filter housing, and power steering reservoir, and visually inspect the power steering hoses for cracks or bulges that could compromise their integrity. Additionally, examine the suspension arms for excessive play or binding, which could suggest further deterioration in the rear bushings. Impending maintenance should include a full oil and filter change, as well as a check of the power steering fluid level and condition, with potential replacement of the power steering pump or hoses if leaks persist. The brake system, despite passing the latest MOT, should be inspected for even wear on the discs and pads, as the previous MOT failure highlighted a critical thickness below the legal minimum. For the buyer’s practical inspection, focus on the vehicle’s structural integrity and fluid condition, given its age and usage profile. Inspect the tyres for signs of sidewall cracking or perishing, which can occur even with moderate mileage if the vehicle has been stored for prolonged periods without rotation or rotation at low pressures. Check the brake discs for corrosion or uneven wear, particularly on the offside front, where the previous MOT noted potential issues. Verify the condition of the 12V battery, as prolonged inactivity can lead to sulphation or poor terminals, which may require a test or replacement if the battery is more than five years old. Finally, since the vehicle has not undergone a full service in recent years, consider checking the service book for any scheduled maintenance, such as timing belt replacement (if applicable), and ensure that fluids like brake fluid, coolant, and transmission fluid are within their service intervals, as these can degrade over time regardless of mileage. A comprehensive inspection of the exhaust system for leaks or corrosion is also advisable, given the advisories around power steering components, as exhaust leaks can indicate underlying structural or gasket issues.
