2025 BYD Seal U Boost DM-I Phev Auto Hybrid electric (clean) · LE25 DYC

The DVSA records show that no MOT test has been logged for this 2025 BYD Seal U‑Boost DM‑I PHEV, meaning there is no documented outcome to assess whether the vehicle’s maintenance history is stable, deteriorating or improving. The absence of any MOT entries suggests either that the car has not yet reached the point at which a test is required, or that the test has not been recorded with the DVSA database; consequently no trend can be established from official data. Mileage information is not supplied, so an objective comparison with the vehicle’s age cannot be made. For a 2025 model, a typical annual accumulation would be in the region of eight to twelve thousand miles, giving an expected figure of roughly twenty‑four to thirty‑six thousand miles by 2026. In the absence of a recorded odometer reading, the prospective buyer should treat the vehicle as potentially low‑mileage but must verify the actual distance travelled through the service book, any digital vehicle‑history reports, and a physical inspection of the instrument cluster and wear patterns on the tyres and steering components. Given the lack of MOT data and an unknown mileage figure, the buyer should conduct a thorough visual and functional examination focused on time‑related wear. The tyre sidewalls should be inspected for cracking, dry rot or uneven tread wear that may indicate mis‑alignment or suspension degradation; the alloy wheels ought to be checked for corrosion, especially around the valve stems, as standing vehicles can develop rust on the rim beads. The high‑voltage battery pack and the 12‑volt auxiliary battery should be tested for state of charge and capacity, since a PHEV that has been idle for extended periods can suffer cell imbalance or sulfation, leading to reduced electric‑drive range and potential warning lights on the dash. Brake discs and pads should be examined for surface rust, glazing or uneven wear, and the calipers should be turned to feel for any binding that could cause shudder under braking. On the road, the buyer should listen for any clunk, squeak or rattle emanating from the suspension bushes, control arms or subframe, which could signal worn bushings or deteriorated coil springs. A test‑drive should include a gentle acceleration to assess the electric motor’s torque delivery and any hesitation that might point to battery management issues, followed by a steady deceleration to gauge regenerative braking performance. Finally, the buyer should confirm that the service history includes calendar‑based fluid changes—engine oil, coolant, brake fluid and the hybrid coolant—because fluids degrade over time even when the vehicle is not driven heavily, and any lapse can lead to premature component wear or corrosion.
