2026 BYD Seal 6 Comfort DM-I Phev Auto Hybrid electric (clean) · LG26 PFD

No MOT history is currently available for this 2026 BYD SEAL 6 COMFORT DM-I PHEV AUTO, which is entirely expected given that the vehicle is of the current registration year and would not yet have accrued the minimum three years of age required to fall within the statutory MOT testing window under DVSA regulations. As a brand new or near-new vehicle, there are no recorded pass or fail outcomes, advisories, or defect trends to evaluate, meaning any assessment of a stable, worsening, or improving maintenance pattern cannot be drawn from official testing data at this stage. The absence of MOT history should therefore be interpreted as a neutral data gap rather than a negative indicator, with the buyer advised to rely instead on the manufacturer's warranty cover, pre-delivery inspection records, and the supplying franchised dealer documentation to verify the vehicle's roadworthy condition. Regarding recorded mileage, no odometer reading has been supplied, and there is insufficient data to compare the vehicle's usage against its age. Given the September 2026 registration date and the current evaluation date, the vehicle is at most a few months old, meaning any mileage accrued would represent only initial delivery miles and early ownership running. Without comparative mileage data across previous test records, it is not possible to identify gaps in usage, periods of standing, or accelerated accumulation that could carry mechanical implications. The buyer should therefore request a clear written record of the current odometer reading and verify it against the warranty and service book entries to establish a baseline for future maintenance planning. As this is a new-generation plug-in hybrid electric vehicle with no prior MOT record to scrutinise, the buyer should focus practical inspection efforts on age- and standing-related degradation rather than wear-based defects. Although the tyres will not yet be subject to tread wear concerns, it is prudent to inspect the sidewalls for any manufacturing date coding anomalies or transit damage, confirm correct pressures in both the conventional and any temporary mobility components, and verify that the 12V auxiliary battery, which remains a known service item on PHEV powertrains regardless of age, is functioning correctly with no dashboard warnings relating to hybrid system readiness or state of charge irregularities. The high-voltage traction battery should be confirmed as holding adequate charge through a full overnight domestic charging session and a subsequent extended drive cycle to verify consistent electric-only range against the manufacturer's claimed figures. Additional inspection priorities should include a thorough under-bonnet and under-vehicle examination for any transit-related fluid leaks from the petrol engine oil circuit, coolant reservoir, or PHEV-specific cooling systems, as even factory-fresh vehicles can occasionally exhibit weeping gaskets or loose hose clips prior to delivery. The brake discs and calipers, although unlikely to show significant wear, should be checked for any surface corrosion from short delivery journeys, as new vehicles that have completed only slow-speed delivery miles are particularly susceptible to disc surface oxidation that can manifest as initial brake shudder under the first firm application. All factory-fitted drive belts should be confirmed correctly tensioned, and the exhaust system, including any particulate filters associated with the petrol range-extender unit, should be visually checked for secure mounting and absence of rattles on a road test. Finally, the buyer should verify that the service book is correctly opened and stamped or digitally recorded by the supplying dealer, that the in-car infotainment, driver assistance, and safety systems such as autonomous emergency braking and lane keep assist are fully functional through a comprehensive system walkthrough, and that all owner manuals, charging cables, and locking wheel nut keys are present and accounted for before completing the purchase.
