2017 Peugeot Horizon 1.6L Diesel · SF67 CDY

A 2017 Peugeot Horizon with this much distance on the clock presents a roadworthiness profile dominated by usage rather than by isolated mechanical defects. Across eight recorded DVSA tests spanning 2020 to 2026, the vehicle has not failed a single examination, and only three advisories have been raised in total. The most recent test on 9 June 2026 recorded a pass with a single advisory for a slightly discoloured nearside rear direction indicator, while the three prior annual tests in 2025, 2024, and 2023 returned clean results with no advisories at all. The only earlier flagging of note sits in the 2022 August test, which captured a deteriorating rear number plate and cracking or perishing on both front tyres. The overall trend is therefore one of consistent roadworthiness rather than a chronic deterioration pattern, with advisories that are minor and largely cosmetic in nature rather than structural or safety-critical. Against an age of approximately nine years, the recorded 182,768 miles equates to a mean accumulation of around 20,300 miles per year, which is high for a passenger vehicle of this vintage and substantially above the typical 7,000 to 10,000 miles expected of privately used cars. The MOT history shows tests in 2020, 2021 (two occasions), 2022 (two occasions), 2023, 2024, 2025, and 2026, with no extended gaps that would suggest prolonged standing off-road, and the regular annual cadence combined with high mileage points to sustained commercial or long-distance private use. From a mechanical standpoint, this kind of mileage profile concentrates wear on the consumables and mid-life drivetrain components rather than on body corrosion, meaning closer attention should be paid to clutches, dual-mass flywheels, turbochargers (where fitted), injector condition, and the supporting engine ancillaries such as water pumps, timing chain stretch, and engine mounts. For a prospective buyer, the priority components to interrogate are the suspension and braking systems, which carry the heaviest workload on a high-mileage vehicle but have produced no advisories on record. On a test drive, listen for knocking or clonking over uneven surfaces that would suggest worn anti-roll bar links, droop links, or trailing arm bushes, and feel for vagueness or wandering through the steering that can indicate worn front wishbones or track rod ends. Inspect the brake pedal for excessive travel or sponginess, which on a diesel platform of this age can indicate binding or seized caliper slide pins rather than simple pad wear, and check the discs for an obvious lip or scored surface. Pay particular attention to any diesel-specific concerns such as EGR valve sticking, DPF warning lights on the dash, and turbo whistle or surge under load, all of which become more probable at this mileage even though the MOT emissions testing has not yet flagged them. The advisories that have been recorded also merit focused verification. The 2022 front tyre perishing notes, although recorded as slight, suggest that the original rubber compound had reached the end of its service life; confirm that the replacement tyres currently fitted are of consistent quality and have adequate tread depth across the full width, as uneven wear can mask suspension geometry issues. The deteriorated rear number plate is purely an administrative and cosmetic item and should not influence the mechanical evaluation, but it is worth checking that no further deterioration has occurred since the advisory was raised. Finally, the slightly discoloured rear indicator lens noted at the most recent test does not affect function, but it is a sensible prompt to walk around the vehicle and confirm that all other lenses are intact, that the wiper blades clear the screen effectively, and that there is no evidence of fluid leaks beneath the engine or rear differential when the vehicle is moved from a cold start.
