2026 BYD Seal U Boost DM-I Phev Auto 1.5L Hybrid electric · AF75 SFK

There is currently no MOT history available for this vehicle, which is consistent with its 2026 registration date. In the United Kingdom, new vehicles are exempt from the mandatory MOT testing regime for the first three years of their life. Consequently, it is impossible to establish a mechanical maintenance trend or identify a history of structural or safety defects through official DVSA records at this stage. The vehicle's roadworthiness must be evaluated based on its physical condition, the integrity of its components, and the presence of a verifiable manufacturer service history rather than past test outcomes. Regarding the recorded mileage, there is insufficient data to perform a comparative analysis against the vehicle's age. Without a documented mileage progression, it is impossible to determine whether the vehicle has been subjected to high annual usage or if it has been largely stationary. For a plug-in hybrid electric vehicle of this age, an absence of mileage can be as significant as high mileage, as prolonged periods of inactivity can lead to specific component degradation, particularly within the high-voltage battery systems, electronic control modules, and various fluid-based cooling circuits. As a prospective buyer, you should conduct a thorough physical inspection to compensate for the lack of MOT data. Given the vehicle's likely low mileage, pay close attention to the condition of the brake discs and calipers; vehicles that sit for extended periods can suffer from surface corrosion on the discs or binding calipers, which may manifest as a pulling sensation or a rhythmic scraping noise during a test drive. Inspect the tyres for any signs of perishing or sidewall cracking, which can occur even if the tread depth remains high if the vehicle has been stored in suboptimal conditions. Furthermore, verify the health of the 12V auxiliary battery, as these are prone to discharge if the vehicle is not driven regularly. Ensure that all fluid levels, including engine oil, coolant, and brake fluid, are correct and show no evidence of weeping or leaks from seals and hoses. For this specific PHEV model, confirm that the charging port and onboard charging equipment are in good working order and that the manufacturer's electronic service record is up to date. During your test drive, listen for any unusual suspension clunks or vibrations that might indicate issues with the bushings or mounting points, despite the vehicle's young age.
