2025 BYD Dolphin Design EV Electric · FH74 MPY

As of the latest available DVSA records, there is no MOT history on file for this 2025 BYD DOLPHIN DESIGN EV, which is entirely consistent with its age. In the United Kingdom, vehicles first registered less than three years before the current date are exempt from compulsory MOT testing, meaning a car of this model year would not yet have required its first statutory roadworthiness examination. Consequently, no advisory notes, failure points, or defect trends can be evaluated from official data. The absence of an MOT record therefore reflects the vehicle's newness rather than any oversight or irregularity in compliance, and there is no historical maintenance trend, whether stable, worsening, or improving, against which to benchmark the car's condition. Recorded mileage is not provided for this vehicle, and the available data is insufficient to draw meaningful comparisons between annual usage and the car's age. Because the model year is 2025 and the assessment date is September 2026, the vehicle is approximately one year old, and any mileage figure would represent a relatively short accumulation period. Without confirmed odometer readings across multiple data points, it is not possible to determine whether the car has been used lightly as a secondary urban runabout, driven at an average rate, or accumulated higher mileage consistent with commuter or fleet use. Buyers should verify the current odometer reading against the sale listing and, where possible, request the digital mileage record from any connected telematics or service history documentation, as EVs with low recorded distance may still have experienced significant calendar-based degradation of certain components irrespective of distance covered. Given the absence of MOT history and the limited mileage context, the prospective buyer should undertake a thorough physical inspection focused on age and time-related deterioration rather than distance-based wear. Tyres should be examined closely for sidewall perishing, cracking, and ozone-related degradation, which can affect relatively new tyres left standing for prolonged periods; tread depth should be measured even if the wear pattern appears minimal, and the manufacturing date code on the sidewall should be checked for age. Brake components warrant particular attention on a low-mileage or infrequently driven EV, as the regenerative braking system reduces reliance on conventional friction braking, which can lead to corrosion on the brake discs and potential caliper binding from prolonged inactivity. On a test drive, listen for any scraping or pulsation through the brake pedal, as corroded discs may produce juddering under initial application, and verify that the vehicle rolls freely with no resistance when lifted or pushed. Additional checks appropriate to this profile include verification of the 12V auxiliary battery state of health, as low-use vehicles are prone to premature depletion of the conventional lead-acid battery, which can trigger dashboard warnings and starting faults even on EVs. High-voltage battery management diagnostics should ideally be requested from a BYD-authorised dealer to confirm state of charge retention and cell balance, particularly if the vehicle has been stored for extended periods. Coolant systems for the electric drivetrain and battery thermal management should be inspected for any signs of leakage or staining, and the charging port, cable, and connector examined for wear or damage. Finally, buyers should confirm that all time-based servicing schedules, including brake fluid replacement, cabin filter changes, and reduction gear oil inspection, have been carried out in accordance with manufacturer intervals rather than purely mileage-based criteria, and should request full dealership service records to evidence compliance with BYD's warranty conditions.
