2002 Peugeot 406 2.0L Diesel · MH02 HTY

Recorded against a single Dipped-beam headlamp failure in late 2020, the MOT history for this Peugeot 406 otherwise reads as a stable, largely clean sequence of pass results running from December 2019 through to the most recent test on 13 January 2026. The vehicle has been presented for testing every year without any subsequent failure, and the last four examinations have all returned passes with no advisories or minors recorded, suggesting that the most recent roadworthiness position is consistent with the longer trend. The only meaningful defects in the documented record are the 2020 headlamp Major items, a 2019 cluster of tyre wear and brake balance advisories, and a 2021 advisory pair relating to the handbrake mechanism and a rear shock absorber. The cumulative picture is one of a vehicle that has remained compliant at test, with isolated wear issues flagged along the way rather than any escalating or systemic defect pattern. Mileage of 161,340 miles across roughly 24 years equates to an annual accumulation of approximately 6,700 miles, which sits broadly in line with average use for a vehicle of this age. The testing intervals are annual and contiguous, with no prolonged lay-up gaps, and the mileage trend within the MOT record is incremental rather than erratic, consistent with steady driving rather than extended storage or sudden heavy use. For a diesel-engined 406 of this vintage and mileage, this usage pattern implies that consumables such as clutch, turbocharger, dual mass flywheel, suspension components and brake hydraulics will have been worked regularly but not excessively, and that corrosion progression has continued normally rather than being accelerated by long periods of disuse. The 2021 advisory concerning the rear nearside shock absorber showing light oil misting is the single most important item to investigate physically, as external oil film on a damper is the early indicator of internal seal failure, and Peugeot 406 rear dampers are known to deteriorate progressively once misting begins. On a test drive, listen for clonking or knocking from the rear over uneven surfaces, particularly mid-corner over bumps, and observe whether the body takes more than one oscillation to settle after pressing down on each rear corner. The accompanying handbrake advisory noting the nearside rear could do with a service warrants checking the lever travel, the feel of the ratchet mechanism, and whether the vehicle pulls to one side or holds less securely on an incline, with specific attention to the condition of the rear caliper mechanisms and cables. Because the 2019 test flagged front brake imbalance with all four tyres worn close to the legal limit, the brake discs and pads should be inspected for lipping, hot judder under firm pedal pressure, and any pulling to either side during braking, while the tyres should be checked for uneven shoulder wear which can indicate alignment or suspension geometry wear. Beyond these flagged items, prospective buyers should make a point of examining the front suspension arms, anti-roll bar bushes and top mounts for splitting or play, as these are common wear points on high-mileage 406s and are not specifically itemised in the MOT record but typically accompany the mileage shown. The underbody and subframe areas should be inspected for corrosion, paying particular attention to the rear subframe mounting points and the inner sills, which are known corrosion zones on this model. Steering should be checked for looseness around straight-ahead and for any clonks over speed humps, which can indicate worn drop-link bushes. Given the 2020 dipped-beam headlamp failure, both headlamp units and their connector integrity should be confirmed, and the cooling system, including the radiator, hoses, and water pump area, warrants a visual check given the age and mileage of the vehicle.
