LeafSpy is designed for the 2011 thru 2017 Nissan Leaf. For the 2018 Leaf you will need LeafSpy Pro which supports all model years. Before you purchase "Leaf Spy" or the more advanced "Leaf Spy Pro" please be sure to first install the Free version "Leaf Spy Lite" to confirm you have a phone (or android device) and ELM327 OBDII Bluetooth adapter that works with your Leaf.
