2023 Peugeot 308 GT Premium SW SS Phev Auto 1.6L Hybrid electric (clean) · BA23 FXP

The most recent DVSA MOT test recorded against this 2023 Peugeot 308 GT Premium SW PHEV is a Pass dated 14 August 2026, with no advisories or defects noted on the certificate. However, it is worth noting that the same date also carries a Fail entry for a major defect on the offside front tyre, where a cut in excess of the prescribed limits exposed the ply or cords. This is significant because an MOT failure and pass recorded on the same day strongly suggests the tyre was replaced and the vehicle subsequently re-presented and passed within hours or days, rather than indicating any underlying structural or mechanical concern with the car. The overall maintenance trend therefore appears stable, with no recurring advisory items across the visible test history and no evidence of deterioration in brake, suspension, suspension component, or emissions performance. With a recorded mileage of 18,038 miles over approximately three years, this vehicle is accumulating at roughly 6,000 miles annually, which is broadly typical for a modern PHEV of this class and consistent with mixed commuting and occasional longer journey use. There are no significant gaps in the mileage record to suggest prolonged periods of standing, nor any unusually rapid accumulation that would indicate high-stress use such as heavy motorway mileage or frequent towing. The PHEV powertrain should have been exercised regularly enough to maintain battery conditioning and keep the combustion engine and its ancillaries, including the 12V auxiliary battery, oil, and coolant systems, in sound working order. The hybrid system and high-voltage battery condition cannot be assessed through MOT data alone, so independent verification of state of health through a dealer or specialist diagnostic read would be prudent. Given the clean MOT record and modest usage profile, a prospective buyer should focus on age- and use-related items rather than chasing specific defect patterns. The tyres, being a relatively recent fitment to clear the August 2026 test, should be inspected for even wear across the axle and for any sidewall perishing or cracking, as Peugeot original-equipment tyres on lower-mileage cars can develop age-related degradation well before the tread is exhausted. Particular attention should be paid to the offside front corner to confirm the replacement tyre is of correct specification, load index, and speed rating, and that the tracking geometry has not been disturbed by any impact that caused the original cut. A test drive should include moderate-speed cornering over uneven surfaces to listen for any suspension knocking, as low annual mileage can allow bushes and top mounts to seize slightly, and firm brake applications from around 40 mph to confirm there is no shudder or pull that might indicate disc corrosion from standing or light caliper binding. Finally, although the MOT history is clean, several time-based service items warrant verification before purchase. The 12V auxiliary battery in PHEVs is known to suffer from parasitic drain and may require replacement regardless of mileage, so its resting voltage and state of charge should be checked. Brake fluid is hygroscopic and typically requires replacement every two to three years irrespective of use, and the coolant and transmission fluids should be confirmed as within their manufacturer service intervals. The high-voltage traction battery and charging system should be verified through a diagnostic tool capable of reading the actual state of health rather than just the displayed range, as PHEV range figures can mask significant cell degradation. A thorough under-the-air examination for any fluid leaks from the petrol engine, gearbox, or rear electric drive unit, together with a check of the charging cable, plug, and port for damage or scorching, would complete a sensible age-appropriate inspection.
