VNCI JLR DoIP Jaguar Land Rover Diagnostic Interface

The VNCI JLR DoIP is essentially a diagnostic and programming interface tool that connects between a laptop (running Jaguar/Land Rover OEM software) and the vehicle’s OBD2 port. “DoIP” stands for Diagnostics over Internet Protocol — a modern communication protocol that newer JLR vehicles require for full diagnostics and advanced functions.
