Check the individual vehicle
Confirm trim, wheels, equipment, software and build details rather than relying on registration year alone. The MyBYD SEAL hub links the source and keeps missing fields visibly unverified.
For existing owners
A newer model-year feature does not automatically arrive through software on an earlier car. Hardware and homologation can differ.
