2020 Peugeot 508 Allure SW S/S Phev Auto 1.6L Hybrid electric (clean) · KS20 AEN

The vehicle presented passes its most recent MOT test dated 9 May 2026, although it should be noted that the same date also records a refusal-to-issue certificate for a non-functional windscreen washer, which is a present and easily rectified minor defect rather than a structural concern. Reviewing the four-year test history, there are no recurring mechanical failures, no structural advisories, no brake or suspension defects, and no exhaust or emissions concerns recorded; the only flagged items are an edge-wear advisory on both front tyres in 2025, a child seat obscuring belt inspection and a deteriorated wiper blade in 2024, and the washer issue in 2026. This represents a stable and improving maintenance trend, as each subsequent test has yielded less concerning output and no component has been flagged twice. The recorded mileage of 47,379 miles over six years equates to roughly 7,896 miles annually, which is broadly typical for a private-use estate of this age. The mileage progression between tests appears consistent, with no significant gaps suggesting long periods of standing and no excessive accumulation that would indicate high wear on consumables. For a PHEV powertrain, this mileage profile is reasonable, although it is worth confirming that the high-voltage battery has been exercised regularly, as plug-in hybrids left uncharged for prolonged periods can suffer cell degradation and reduced electric range. Although the MOT record is largely clean, the buyer should not rely solely on it for a roadworthiness judgement given the vehicle's age. Inspect all four tyres closely for sidewall perishing and cracking, as age-related rubber degradation occurs independently of tread depth and is not flagged at test; the 2025 advisory on both front tyres suggests a tendency towards edge wear, which can indicate worn front suspension bushes, top mounts, or tracking misalignment, so listen for clonks from the front end on uneven surfaces and verify the car tracks straight. Check the brake discs for any lipping or surface corrosion, particularly given the PHEV system allows low-speed driving on electric propulsion alone, which reduces brake application and can lead to corrosion build-up and potentially binding calipers over time; on a test drive, expect a firm pedal and steady response without shudder under braking. Additionally, verify the 12V auxiliary battery health, as Peugeot vehicles of this era are known for auxiliary battery failures that can trigger dashboard warning lights and drivetrain faults. Confirm the service book stamps align with Peugeot PHEV requirements, paying particular attention to brake fluid and coolant replacement, both of which are time-sensitive rather than mileage-sensitive and should have been refreshed within the last two to three years regardless of odometer reading. Inspect undertrays and the rear of the vehicle for any oil or coolant seepage, examine the charging cable and port for damage, and ensure the high-voltage system displays a healthy state of charge and realistic electric range. Finally, listen on start-up for any chain or timing rattle from the petrol engine, confirm smooth transitions between electric and hybrid modes, and ensure all warning lamps extinguish promptly upon ignition.
