BD Check is a calm, thorough checklist for your BYD handover, and for buying a used BYD. A handover is a good moment, and a busy one. A light scratch on a door, water inside a light, a warning on the screen or a missing charging adapter is easy to overlook while the paperwork waits. After you sign, it can be much harder to put right, so it helps to find it first. BD Check takes you through the car one point at a time and keeps a record of everything you find. • A step-by-step checklist for the Atto 3, Seal U DM-i (Sealion 6 in Australia), Dolphin Surf, Dolphin, Atto 2, Seal, Sealion 7 and Shark 6, and a general list for other BYD models • Electric and plug-in hybrid (DM-i): paint and body, glass, interior, screens, cameras, wheels, keys, charging and a short test drive • Checks based on the BYD owner's manuals • Mark each point OK or Not OK, and add a photo and a note to any issue • All issues in one place, ready to share as a PDF • A flashlight button for dim garages • Works offline.
