2025 BYD Dolphin Active EV Electric · HV25 BOU

Absence of any recorded MOT tests for the 2025 BYD Dolphin Active EV means there is currently no official evidence of its roadworthiness, leaving the mechanical condition of the vehicle unverified by the DVSA. Because the car is less than three years old, it would not yet have been required to undergo a statutory MOT, so the lack of data does not imply a pattern of failures but simply a gap in formal testing. Mileage information has not been supplied, preventing any comparison of annual kilometre accumulation against typical usage for a vehicle of this age. Without a recorded odometer reading, it is impossible to gauge whether the Dolphin has been driven lightly, heavily, or intermittently, and consequently the wear levels on drivetrain, suspension and braking components cannot be inferred from mileage alone. Given the absence of MOT‑recorded defects, a prospective buyer should arrange a comprehensive pre‑purchase inspection that concentrates on the EV‑specific systems and the conventional mechanical items that would normally be examined at an MOT. For the high‑voltage battery pack, request a state‑of‑charge and health report from the dealer or a qualified EV technician, and listen for any abnormal humming or excessive heat from the cooling circuit during a short drive. Inspect the battery cooling hoses and connections for signs of leakage or corrosion, and verify that the vehicle’s on‑board diagnostics display no fault codes relating to the battery management system. During the road test, pay close attention to the steering feel and suspension response; any clunking over bumps may indicate worn bushings or deteriorated coil‑spring mounts that would ordinarily be flagged at a MOT. Evaluate the regenerative braking engagement and the conventional hydraulic brakes for consistent pedal travel and the absence of pulsation, which could reveal hidden disc or caliper wear. Finally, have a qualified mechanic perform a visual inspection of the chassis for any concealed corrosion, especially around the under‑body and wheel arches, and confirm that all lighting, horn and emissions‑related systems (such as the exhaust‑gas recirculation valve, if fitted) operate within legal limits before committing to purchase.
