2025 BYD Seal 6 Comfort LTE DM-I Phev A Hybrid electric (clean) · LE75 CYP

As of the assessment date in September 2026, there is no official DVSA MOT test history recorded for this 2025 BYD SEAL. Under current UK roadworthiness legislation, vehicles first registered within the last three years are legally exempt from compulsory MOT testing until they reach the appropriate anniversary, meaning this absence of data is entirely expected and cannot be interpreted as a positive or negative maintenance indicator. With no test outcomes, advisories, or failure records available for review, it is not possible to establish a maintenance trend. The prospective buyer must therefore rely entirely on a comprehensive pre-purchase inspection, dealer service records, and the manufacturer's warranty documentation to gauge the mechanical condition of this plug-in hybrid vehicle. The recorded mileage is listed as unknown, and there is insufficient data to compare annual usage against the vehicle's age or to identify any unusual gaps or rapid accumulation patterns. Given that the car is only a year old and based on a modern hybrid powertrain, average annual mileage for this sector typically ranges between 8,000 and 12,000 miles, though plug-in hybrids often record lower figures due to urban electric-only running. The absence of verifiable mileage history makes it essential to confirm the exact odometer reading at the point of sale and cross-reference it with any digital service records held by franchised dealers, ensuring there is no clocking discrepancy and that the high-voltage battery and 1.5-litre petrol engine have been exercised appropriately rather than left dormant. Given the lack of MOT data, physical inspection should focus on age-related and standing-related degradation even at this early stage. Tyres should be examined closely for sidewall cracking, perishing, or uneven wear patterns, particularly as a PHEV of this weight and torque output places considerable demand on the contact patches, and any original fitment over twelve months old may have begun to harden. Brake discs and calipers should be inspected for corrosion or binding, as vehicles driven predominantly in electric mode rely heavily on regenerative braking, which can lead to conventional friction components seizing from infrequent use. The 12V auxiliary battery should be tested for state of charge, the high-voltage traction battery health should be verified through a diagnostic scan, and all fluid levels including coolant, brake fluid, and the petrol engine oil should be checked for condition and service intervals, as time-based degradation can occur regardless of mileage covered. On a test drive, particular attention should be paid to the transition between electric and petrol power, listening for any unexpected vibrations, clonks from the suspension over uneven surfaces, or harshness from the continuously variable transmission. The regenerative braking system should be assessed for consistency, and the driver should ensure there are no warning lights illuminated on the digital dashboard, particularly relating to the hybrid system, emissions, or brake regeneration. Finally, verifying that the onboard charging system functions correctly via both domestic and dedicated rapid sources will confirm the integrity of the plug-in hybrid drivetrain, while ensuring all manufacturer recalls and software updates have been completed will provide additional peace of mind before committing to the purchase.
