2026 BYD Seal U Boost DM-I Phev Auto 1.5L Hybrid electric (clean) · SP60 AGE

The DVSA records show that no MOT test has been recorded for this 2026 BYD SEAL U BOOST DM‑I PHEV, which is expected for a vehicle that is less than three years old and therefore not yet subject to a statutory test. Consequently there is no trend data to assess, and the maintenance history cannot be judged as stable, worsening or improving from MOT results alone. Mileage information is not supplied, so a quantitative comparison with the vehicle’s age cannot be made. Assuming the car is a recent registration, typical annual mileage for a new PHEV would be in the range of 5‑8 000 miles per year for a private owner; any substantially higher figure would suggest intensive use and could accelerate wear on the brake discs, tyre tread and suspension bushings, while very low mileage might indicate prolonged periods of storage which can affect battery electrolyte balance and cause tyre sidewall perishing. Given the lack of MOT data and the likely low‑to‑moderate usage, the buyer should focus on age‑related inspections. Examine the tyre sidewalls for cracking, dry rot or uneven wear that can develop even on low‑kilometre cars left stationary for long periods. Verify that the 12‑volt auxiliary battery is holding charge and that the high‑voltage pack shows no warning lights on the instrument cluster; a full charge‑hold test at a reputable service centre can confirm the health of the lithium‑ion modules. Check all fluid reservoirs – brake fluid, coolant and power‑steering fluid – for correct level and any signs of contamination, as these fluids degrade over calendar time regardless of mileage. During a test drive, listen for any clunk or squeak from the front suspension, particularly around the control‑arm bushes and coil‑spring mounts, which can develop early if the vehicle has been subjected to rough road surfaces while still under warranty. Observe the braking response for any pulsation or delayed pedal return that might indicate early disc corrosion or caliper sticking, especially if the car has been parked for extended periods. Finally, confirm that the service book contains the manufacturer’s scheduled 12‑month or 10 000‑mile service entry, and that any software updates for the PHEV’s battery management system have been applied, as these are critical to long‑term reliability and resale value.
