2006 Peugeot 407 1.6L Diesel · DY56 AAN

The vehicle's roadworthiness shows signs of worsening following a period of relative stability. While the car passed tests between 2020 and 2023 without recorded defects, the most recent MOT on 15 June 2026 at 157,726 miles introduced two significant concerns. The tester flagged corrosion on the outer integral body structure, specifically affecting both outer sills, although the report notes structural rigidity remains largely intact. A front oil leak was also identified, though it was not classified as excessive at the time of testing. The mileage accumulation is consistent with a vehicle of this age, averaging approximately 7,886 miles per year over its lifespan. The record shows steady usage without significant periods of dormancy or sudden spikes in mileage. Between the December 2022 test at 144,824 miles and the December 2023 test at 152,545 miles, the vehicle covered roughly 7,700 miles, mirroring the long-term average. This predictable usage pattern suggests the vehicle has been in regular service rather than sitting stationary for extended periods. A prospective buyer must prioritise a thorough inspection of the vehicle's underside to assess the extent of the sill corrosion. While the 2026 report suggests the integrity is not yet compromised, rust on integral body structures can progress rapidly. The presence of a front oil leak also necessitates a closer look at the engine and associated seals to determine if the leak is a minor seepage or a symptom of a more significant mechanical failure. The history also reveals a recurring pattern of ABS faults, with the warning lamp appearing in multiple tests between 2016 and 2021. Although these issues appear to have been resolved or were not present during the 2022 to 2024 period, the electronic braking system should be verified for reliability. Previous advisories regarding pitted brake discs and suspension ball joint play suggest that while the car has been maintained, the buyer should check the current condition of all consumables, particularly the braking components and front suspension bushings.
