2026 BYD Sealion 5 Comfort Phev Auto 1.5L Hybrid electric · LC26 PLU

As a 2026 model year BYD Sealion 5 Comfort PHEV, this vehicle is currently within its first year of registration and therefore has no recorded DVSA MOT history, as it will not become eligible for its first MOT test until three years after first registration. Consequently, there are no test outcomes, advisory notices, or failure points to evaluate against the official MOT database, meaning the maintenance trend cannot be assessed through statutory testing records at this stage. Any appraisal of this vehicle's roadworthiness must therefore rely entirely on a physical inspection, pre-delivery inspection records, and the manufacturer's service history rather than on governmental test data. The recorded mileage is listed as unknown, which makes it impossible to calculate an accurate annual usage rate or to determine whether the vehicle has been driven consistently, used predominantly for short urban journeys, or left standing for extended periods. For a plug-in hybrid of this type, both very low mileage and exclusively short-trip usage can present specific mechanical concerns, including potential degradation of the high-voltage traction battery due to irregular charging cycles, increased carbon build-up in the combustion engine from insufficient running temperature, and accelerated wear of conventional service items such as engine oil and coolant. A prospective buyer should establish the true mileage through the vehicle's on-board trip computer, the digital service record, or a connected app history, and should verify whether the car has predominantly been charged and used in EV mode or has seen regular long-distance running to keep the internal combustion components in good working order. In the absence of MOT data, a thorough physical inspection becomes paramount. The buyer should check all four tyres, including the spare or repair kit, for signs of sidewall perishing or cracking, as even low-mileage tyres deteriorate with age and exposure to ultraviolet light, and the production date code on each sidewall should be reviewed to ensure the tyres are not excessively old. The braking system, particularly the rear calipers and discs, should be examined for corrosion or seizure resulting from prolonged standing, while the 12-volt auxiliary battery and the high-voltage hybrid battery state of health should be verified through diagnostic equipment capable of reading the BYD systems. All fluid reservoirs, including the engine oil, coolant, brake fluid, and any reduction gear or hybrid transmission fluid, should be inspected for correct level and condition, bearing in mind that brake fluid is hygroscopic and typically requires replacement every two years regardless of mileage, and engine oil in a PHEV that rarely runs the combustion engine may still degrade over time. On a test drive, the prospective buyer should pay close attention to the transition between electric and hybrid modes, listening for any unusual mechanical clunks, vibrations, or hesitation that could indicate issues with the hybrid drivetrain or engine mounts. The regenerative braking system should be tested across its various settings to ensure smooth deceleration without warning intervention from the friction brakes, and the vehicle should be driven over uneven road surfaces to detect any suspension knocks, thuds, or rattles that might suggest worn bushes, dampers, or anti-roll bar links. The infotainment system, driver assistance functions, and charging port operation should all be verified for correct function, and the vehicle should be subjected to a professional pre-purchase inspection by a technician familiar with BYD plug-in hybrid models to confirm the integrity of the high-voltage system, the condition of the battery pack, and the completeness of the manufacturer's warranty coverage before any commitment to purchase is made.
