2026 BYD Sealion 5 Comfort Phev Auto 1.5L Hybrid electric (clean) · LE75 MYF

No MOT test history is currently recorded for this 2026 BYD Sealion 5 Comfort PHEV automatic, and consequently there is no official DVSA test outcome to report. As the vehicle is registered in 2026, it is likely too new to have yet required its first compulsory MOT test, which is mandated only after three years from the date of first registration. In the absence of any test records, the prospective buyer cannot rely on official pass or failure data to establish a maintenance trend or to identify recurring defect patterns. The absence of MOT history at this stage should be regarded as a neutral factor rather than a red flag, provided that the vehicle is being sold well within its first three years of registration. Recorded mileage is not available, and with such limited data it is impossible to make any meaningful comparison between annual usage and the vehicle's age. A new plug-in hybrid of this type could plausibly be used for low-mileage urban commuting, moderate mixed driving, or higher mileage longer-distance motoring, each of which places different demands on components such as the high-voltage battery, the petrol engine, the regenerative braking system, and the conventional friction braking components. Buyers should request full dealer or independent service records and a documented mileage history to verify usage patterns, as inconsistencies or rapid mileage accumulation can be an indicator of prior fleet, rental, or chauffeur use, which may bring accelerated wear on tyres, brakes, and suspension components. In the absence of MOT data, a thorough physical inspection is essential. The tyres should be examined closely for any signs of sidewall perishing or cracking from age or prolonged standing, even if tread depth appears adequate, and particular attention paid to ensure that all four tyres are of matching specification and age, which is important for the proper functioning of any traction or stability control systems. Brake discs and calipers on a vehicle that may have stood for extended periods are prone to surface corrosion and seizing; therefore, the calipers should be checked for smooth operation and the discs inspected for any significant lipping, pitting, or uneven wear that would suggest binding. The high-voltage battery state of health should be verified through a diagnostic scan, and the 12-volt auxiliary battery tested for adequate cranking voltage, as modern PHEVs are highly dependent on the integrity of both systems. Time-based servicing items should also be carefully reviewed regardless of mileage. Engine oil, coolant, brake fluid, and transmission fluid all degrade with calendar age and require periodic replacement according to manufacturer schedules, and the absence of recent mileage does not negate this requirement. The underbody and suspension components, including coil springs, bushes, and anti-roll bar links, should be inspected for any signs of standing corrosion, fluid leaks from the petrol engine, or deterioration of rubber components that may have occurred while the vehicle was stationary. Given the plug-in hybrid powertrain, it is also prudent to confirm the operation of both the electric drive mode and the petrol engine transition, ensuring that the charging cable and port are undamaged and that the vehicle's software systems are fully updated. Any service history, warranty documentation, and prior diagnostic reports should be scrutinised carefully to confirm that the vehicle has been maintained in accordance with BYD's official schedule.
