Home › Models › BYD Seal › Repair
Welcome to the repair and maintenance hub for the BYD SEAL, a fully electric sports saloon launched in the UK in 2023. Maintaining an electric vehicle differs from traditional internal combustion engine cars because there is no petrol engine, exhaust system, or traditional multi-speed gearbox.
This hub connects you to general reference guides on the various systems within the BYD SEAL, from its high-voltage Blade Battery to its advanced infotainment and suspension setups. Because the BYD SEAL features complex electronics, Advanced Driver Assistance Systems (ADAS), and a high-voltage architecture, repairs are strictly dealer-only. High-voltage components must not be opened by owners. Always check your owner’s manual for user-level maintenance and confirm with an authorised BYD dealer or qualified workshop for complex diagnostics and repairs. BYD’s own procedure applies to all major service work.

Dealer-only work
Certain tasks on the BYD SEAL are classified as dangerous work and must only be undertaken by trained professionals. This includes any interaction with the orange high-voltage cables, the traction battery, airbag systems, steering components, and the sensors and cameras that enable the ADAS functions (like the 360° camera and Blind Spot Detection). Any interference with these systems by unqualified individuals may void the vehicle’s warranty and pose severe safety risks.
