2001 Peugeot 406 2.0L Diesel · Y771 AGK

The vehicle passed its most recent MOT test on 19 March 2026 with a number of advisories and one minor defect recorded, indicating that while the car was deemed roadworthy at the point of test, several wear-related items require monitoring. Looking at the broader MOT history, the maintenance trend is broadly stable but with a clear progressive deterioration in several areas, most notably the brake discs and tyres, which have appeared as advisories on nearly every test for the past four years. The most recent failure on the same date for an ineffective front windscreen wiper is a straightforward serviceable item, and the recurring minor defect regarding the offside front outer drive shaft CV boot deterioration is a more pressing concern that warrants immediate attention before it progresses to a failure. Overall, the advisory pattern suggests an ageing vehicle where consumable wear items are accumulating and structural corrosion is beginning to manifest, particularly on the sub-frames and brake pipework. The recorded mileage of 140,419 miles against an approximate age of 25 years equates to an average of around 5,617 miles per year, which is notably low for the vehicle's age and points to either prolonged periods of standing or genuinely light usage. While low annual mileage reduces wear on major drivetrain components such as the engine, clutch, and gearbox internals, it simultaneously accelerates calendar-related degradation elsewhere, including ageing of rubber components, corrosion on exposed metal, and fluid degradation through lack of regular circulation. The MOT records do not show any obvious annual mileage gaps that would suggest long periods off the road, but the relatively even MOT test dates and consistent low-mileage progression imply a car that has been used sparingly and possibly stored for intervals, which carries its own mechanical implications. The recurring advisories across multiple tests deserve close scrutiny from a prospective buyer. The front and rear brake discs have been flagged as worn, pitted, or scored on every MOT since 2022, indicating progressive surface corrosion and wear that will eventually require disc replacement, particularly if sharp juddering or pulsing is felt through the brake pedal under firm application. The sub-frame corrosion flagged in 2025 and the corroded brake pipework noted in both 2024 and 2025 are of particular importance, as these structural and safety-critical items can deteriorate rapidly on a vehicle of this age and warrant a physical inspection underneath the car for any advanced rust, flaking, or perforation. The offside rear suspension arm damage noted in 2023 should be re-inspected for any crack propagation, and the deteriorating rear anti-roll bar linkage dust cover from the 2024 failure should be checked to ensure it has been renewed and that no excessive play has developed in the joint itself. The minor engine oil leak and rear exhaust leak are likely to be ongoing seepage items typical of an older Peugeot 406, but both should be monitored for escalation. Beyond the recorded defects, several age-related checks are strongly advised given the low mileage and the calendar age of the vehicle. The offside rear tyre flagged as worn close to the legal limit in the most recent test should be replaced immediately, and all four tyres should be inspected for sidewall cracking or perishing, which is common on infrequently used vehicles. The 12-volt battery is a likely candidate for renewal given the car's age, and the brake hydraulic fluid, engine coolant, and automatic or manual transmission fluid should be regarded as overdue for replacement purely on a time basis, regardless of the mileage covered. On a test drive, particular attention should be paid to any clonks or knocking from the front and rear suspension over uneven surfaces, any binding or dragging sensation from the brakes suggesting seized calipers from standing, and any signs of hesitation, misfire, or excessive smoke from the exhaust indicating neglected servicing. Finally, the deteriorated rear registration plate and headlamp lens deterioration flagged in the records are indicative of the general cosmetic and optical ageing of the vehicle, and any prospective purchase should be accompanied by a thorough pre-purchase inspection on a ramp to verify the structural integrity of the sub-frames and the condition of the underbody brake and fuel lines.
