BYD Sealion 7 Maintenance, Tyres and Parts Planning

Use the market- and year-specific owner information rather than a generic EV interval. Record time and distance triggers, fluid specifications, brake checks, thermal-system work and inspection items. Export history may not appear in destination dealer systems.

After arrival, plan tyre pressures and condition, wheel alignment, brakes, suspension, wipers, filters, lighting, 12-volt battery, thermal fluids and diagnostic scan. Do not change high-voltage parts or fluids without correct procedures and specifications.

Record front and rear sizes, load and speed ratings, production dates and brand compatibility. AWD or performance grades may use larger or staggered tyres. Verify local supply and replacement policy; mismatched rolling dimensions can affect control systems.

Identify a workshop able to read relevant BYD systems and follow safe high-voltage isolation. Ask how software, calibration and parts coding are handled. A general scan tool may show basic codes without providing the required service function.

Select a routine filter, a wear component and an immobilising electronic or charging part. Find the VIN-based number, source, lead time, coding need and shipping constraints. This small exercise exposes realistic downtime and working-capital needs.

Store inspection, diagnostics, part numbers, invoices, software versions, tyre changes and charging faults outside a region-locked app. Good records support later service and resale and help distinguish export preparation from subsequent wear.

Close this specific file by placing market-specific service schedule, arrival baseline checklist and complete tyre codes in one dated candidate record. The reviewer should be able to confirm that ev is not called maintenance-free and that high-voltage work has a competence boundary. Name the person or provider responsible for every unresolved point, add a realistic cost or consequence, and state what evidence will change the decision. If the VIN, version, condition or destination basis changes, reopen this file instead of carrying the previous conclusion into a different purchase.

A useful decision records what is verified, what remains seller-stated and what was not tested. Attach a consequence and owner to each open item. Do not let a broad assurance replace a missing VIN record, charge test, condition image or destination opinion. Acceptance should be explicit: proceed, proceed with a priced condition, obtain more evidence, or reject. A replacement VIN never inherits an earlier acceptance.

Give images, scans, diagnostics and quotations a date, source and vehicle identity. Preserve originals before translation or editing. If custody, software, repair, route or candidate changes, identify which conclusions expire and repeat the affected checks instead of silently carrying them forward. Before inland release, read the same identity, propulsion, value and parties across contract, invoice, inspection and shipping drafts. Registration and customs remain separate destination checks.
