2003 Peugeot 406 2.0L Diesel · KX52 DLF

The vehicle’s most recent MOT test on 2025-05-30 confirms it passed without defects at 140,753 miles, following a rare failure just eight days prior at 140,749 miles. This anomaly—where the car failed once then passed immediately—suggests either a minor oversight in the first test or a temporary issue resolved before retesting. The preceding MOT history from 2022 to 2024 shows consistent passes with no recorded faults, indicating a stable maintenance pattern over the past four years. However, the lack of advisories or defects across all tests implies either meticulous upkeep or that critical components have not yet reached their natural wear thresholds. The absence of recurring advisories for suspension bushes, coil springs, or binding calipers is particularly notable, as these are common failure points in a vehicle of this age and mileage. The recorded mileage of 140,753 miles over 23 years equates to approximately 6,120 miles annually, which is typical for a car of this vintage. There are no significant gaps in mileage between tests, suggesting the vehicle has been driven steadily without prolonged periods of inactivity. The 14-day gap between the 2025 failure and pass does not indicate rapid mileage accumulation but rather a retest scenario. While this average mileage per year aligns with expected wear, a buyer should verify whether the odometer reading has been tampered with, as the consistency of the numbers does not guarantee accuracy. Given the lack of recorded defects or advisories in the MOT history, the primary focus for an in-person inspection should centre on high-wear components that are not routinely tested by the MOT. The suspension—particularly the rear coil springs and bushes—should be examined for excessive play, corrosion, or cracking, as these are often silent failures that do not always trigger MOT failures until they become severe. Brake discs and pads, though not flagged in tests, warrant close inspection for uneven wear or glazing, which could indicate binding calipers or inadequate bleeding. Structural integrity, especially around the wheel arches and sills, should be assessed for corrosion, as a 2003 Peugeot is prone to rust in these areas. Finally, the exhaust system should be checked for leaks or excessive corrosion, as catalytic converter failures are a common late-stage issue in this model. The absence of advisories does not preclude these areas from requiring attention.
