2025 BYD Seal 6 Comfort LTE DM-I Phev A Hybrid electric (clean) · LE75 DOJ

The DVSA database contains no MOT record for the 2025 BYD Seal 6 Comfort LTE DM‑I PHEV, meaning that no official test has been logged and consequently there is no basis on which to judge a maintenance trend; the absence of data precludes any assessment of whether the vehicle’s condition has been stable, deteriorating or improving over time. Mileage for the vehicle is not supplied, so a quantitative comparison with its 2025 model year cannot be made. Assuming a typical annual accumulation of between eight and twelve thousand miles for a privately‑owned car, a vehicle of this age would normally sit in the low‑to‑mid‑teens of thousands; however, an unknown figure could indicate either very low usage, perhaps as a secondary or weekend car, or a lack of proper odometer recording. Low mileage would generally reduce wear on engine, transmission and suspension components, whereas a high, undocumented figure could mask accelerated fatigue of bushings, CV joints and brake wear, and would warrant a more thorough inspection for hidden mileage‑related deterioration. In the absence of a recorded MOT, the buyer should perform a comprehensive visual and tactile examination of the tyre sidewalls for cracking, dry rot or uneven wear that can develop with age even on low‑kilometre cars, and confirm that tyre tread depth meets the legal minimum. The 12‑volt starter battery should be load‑tested to verify capacity, as older batteries can lose charge even when the vehicle sits idle, and the high‑voltage traction battery should be checked for any diagnostic fault codes, capacity loss or coolant level in the battery thermal management system. Brake discs and pads should be inspected for surface corrosion, glazing or uneven thickness, and the calipers examined for signs of sticking or fluid leakage, especially if the car has been stored for extended periods. Finally, all fluid reservoirs—engine oil, coolant, brake fluid and power‑steering fluid—should be examined for colour, level and any evidence of contamination, and the service book should be cross‑checked for timely oil changes, filter replacements and any manufacturer‑recommended calendar‑based servicing. Specific to the plug‑in hybrid architecture, the buyer must verify that the charging inlet and cable are free of corrosion and that the on‑board charger operates correctly, ideally by performing a full charge cycle and monitoring the state‑of‑charge display for consistency. The inverter and DC‑DC converter should be inspected for secure mounting and clean heat‑sink fins, as overheating can precipitate premature electronic failure. A diagnostic scan using a BYD‑compatible tool is advisable to confirm that the high‑voltage battery management system reports healthy cell balance and that any software updates recommended by the manufacturer have been applied. Listening for abnormal whine or vibration from the electric motor during acceleration, and feeling for any judder when the regenerative braking system engages, will help identify early mechanical or control‑system issues before they become costly repairs.
