Full support for dual-K lines found in "new" (B6/8E chassis Audi A4 and 2002+ Audi A6, A8, etc.  Q: What is CAN and why is it important?  A: CAN stands for Controller Area Network. CAN is a new means of communicating with the can for diagnostics used by the latest generations of VW, Audi, SEAT, and Skoda vehicles. Unlike the older ISO9141 system which a used a single K-line for diagnostic communications, the new CAN-Bus system uses a twisted pair of wires with differential signaling. CAN is considerably faster than ISO-9141 (500 kpbs vs. 10.4 kbps). Both new hardware and new software are required in order to communicate with cars using CAN for diagnostics.  Q: Does VAG-COM work with cars that require direct CAN access for diagnostics?  A: Yes! We have integrated CAN compatibility since the Release 404.0 version of VAG-COM, but as CAN uses different hardware, new interfaces are required in order to communicate with a CAN-based car. These are now available as well. The new HEX-COM+CAN and HEX-USB+CAN interfaces are fully compatible with the new latest cars which require a direct CAN connection.  Features:  1. USB connector plugs into most modern laptops!  2.
