2001 Peugeot 806 2.0L Diesel · GV51 KWP

The vehicle's roadworthiness shows a concerning trend of persistent corrosion and recurring mechanical issues despite passing recent tests. The most recent test on 21 October 2025 at 74,418 miles flagged a corroded front brake pipe covered in grease, a defect that has appeared in almost every MOT since at least 2018. While the vehicle has passed its tests, the repetition of this specific advisory suggests that while the immediate safety risk is being managed, the underlying issue of component degradation is not being fully resolved. The mileage pattern indicates very low usage for a 25-year-old vehicle, averaging approximately 2,977 miles per year. This low annual distance is evident in the progression from 49,345 miles in 2013 to 74,418 miles in 2025. While low mileage often implies less drivetrain wear, it can also lead to issues such as seized components or accelerated corrosion due to the vehicle standing for extended periods. The gaps between tests are consistent, but the mechanical history suggests the vehicle has struggled with age-related deterioration rather than high-mileage wear. A prospective buyer must prioritize a thorough inspection of the vehicle's structural integrity and braking system. The record shows significant historical concerns regarding corrosion, specifically a failed test in October 2022 where the offside front sub-frame was found to be seriously weakened at the lower arm mounting point. Furthermore, the November 2019 failure highlighted excessive corrosion on suspension component mounting areas and sills. These are serious structural risks that require physical verification to ensure the chassis remains sound. The suspension and braking components also require close scrutiny. The tester has repeatedly flagged worn bushes, specifically in the anti-roll bar and suspension arms, as seen in the October 2024 test at 72,109 miles. Recurring issues with brake pipes and pitted discs, such as those noted in 2023 and 2020, suggest that the braking system is in a state of constant maintenance. Given the history of fractured coil springs and exhaust leaks, a detailed check of all underside components is essential to confirm that recent repairs have addressed the root causes of these recurring failures.
