Fitment guarantee and VIN verification

Each Gateway module undergoes inspection for mechanical damage, signs of water ingress, and intact pins in the connection sockets.

Fitment note: The Gateway module serves as the main Component Protection node and stores vehicle configuration data. Replacement requires removing Component Protection, adding the module to the VIN, and programming it at a specialized service center. Before purchase, we recommend verifying the suffix letter (G) against the vehicle's VIN.
