  • πŸ”‹ Battery charge - if the voltage is low, the central locking may not operate.
  • πŸ”Œ fuse F36 (10A) in the block under the steering wheel - it is responsible for the electric drive of the sunroof.
  • πŸšͺ State of door limit switches - if at least one door is not completely closed, the system may block opening.
