1997 Peugeot 806 2.0L Diesel · P175 AWL

A near-thirty-year-old Peugeot 806 returning a fully clear MOT on 20 November 2025, with not a single advisory, minor defect, or component comment recorded against the test, is a genuinely unusual outcome for a vehicle of this vintage and platform. The history is consistent rather than progressive: pass on 6 December 2023, a no-defects failure on 5 November 2024 followed by a clean pass on 22 November 2024, then another no-defects failure on 7 November 2025 immediately followed by a pass on 20 November 2025. That back-to-back pass/fail pattern with no recorded defect is a strong indicator that the failures were almost certainly administrative or procedural in nature, such as tyre condition at the time of test or an emissions preparation issue that was remedied within days, rather than a mechanical deterioration curve. Mechanically, the trend is therefore one of stability rather than decline, although the absence of any advisory data across five tests means there is no public record of component wear rates to draw on. At 149,149 recorded miles over roughly 29 years, the annual accumulation sits at approximately 5,143 miles, which is exceptionally low for a family MPV of this era. Peugeot 806s of this generation were typically used as high-mileage family transport, so this figure suggests the car has either been a second or third vehicle, a weekend or holiday-use machine, or has spent extended periods off the road between intermittent use. The MOT gap pattern, with tests only appearing in 2023, 2024, and 2025, supports the possibility of significant lay-up periods earlier in the vehicle's life, which carries well-known implications for a French MPV of this age: perished rubber components, dried suspension bushes, corroded brake calipers and pipes, oxidation in the cooling system, and brittle fuel hoses. The mileage is not high enough to imply worn-out major mechanical items such as the engine or gearbox purely on odometer evidence, but the combination of age and light use is arguably a greater concern for a buyer than high miles would be on a younger car. A prospective buyer should treat the clean test record as encouraging but not conclusive, because the MOT inspection does not cover many of the components most likely to trouble a 1997 806 that has seen long periods of inactivity. On a test drive, listen for clonks or knocks from the front suspension over speed humps and rough surfaces, which would point to worn lower wishbone bushes, anti-roll bar drop links, or top mount deterioration, all of which are common on this platform and would not necessarily have generated an advisory if the wear was within tolerance on the day. Check for uneven tyre wear across both axles, as this is a tell-tale of geometry issues arising from softened suspension bushes. Brake pedal feel should be firm and progressive with no sponginess, and the vehicle should pull up squarely without any pulling to one side, which would suggest a binding or seized caliper after long storage. Under the bonnet, the buyer should look for signs of oil misting or weeping around the cam belt area, the crankshaft seals, and the rocker cover gasket, as these engines are known to develop minor leaks with age, and any staining in these areas can mask more serious issues. Inspect all coolant and fuel hoses for cracking or softness, and confirm the cooling system holds pressure with no visible staining at the water pump or thermostat housing. On the underside, examine the subframe mounting points, brake pipes along their full length, and the fuel lines for any surface corrosion, as the MOT result is only a snapshot. Verify that the timing belt has documentary evidence of recent replacement, as a 29-year-old unit is well beyond any safe interval regardless of mileage. Finally, confirm there are no warning lights on the dashboard, that the air conditioning system functions, and that all the powered rear door and seat mechanisms operate correctly, as electrical faults in the rear quarter of the 806 are a known weak point and would not be visible on the MOT record.
