HEX-USB-CAN VAG-COM FOR 512.4

USB connector plugs into most modern laptops! (USB 1.1 or 2.0)
Compatible with the latest cars which require a direct CAN connection for diagnostics including all Golf-5 platform cars and latest Audi A3, A6 and A8.
Protocol timing indistinguishable from a real VAG/VAS tool. Works reliably even with "difficult" control modules such as the 1991-1994 1Z Audi TDIs and the 1993-1994 Audi 2.6L with Hella ECU.
Built-In VAG-Saver functionality -- instantly alerts the user if either the K/K1 line or the L/K2 line is shorted to Ground or Vbatt.
Full support for dual-K lines found in "new" (B6/8E chassis Audi A4 and 2002+ Audi A6 -- no VAS-6017 required -- no manual switches!
Fully backwards compatible with older cars using a single K-line or
K plus L.
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: What Cars Use CAN for Diagnostics? (Click on the links of info on each vehicle)
All Golf-5 platform cars (A5 platform) including:
2004+ VW Golf (1K chassis)
2003+ VW Touran (1T chassis)
2004+ VW Caddy (2K chassis)
2004+ Audi A3 (8P chassis)
2004+ Seat Altea (5P chassis)
2004+ Skoda Octavia (1Z chassis)
2005+ Seat Toledo (5P chassis)
2003+ Audi A8 and A8L (D3 platform, 4E chassis)
2005+ Audi A6 (C6 platform, 4F chassis)
2005+ Audi A4 ("B7" platform) (some control modules)

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.

Q: Do the CAN-Bus Interfaces also work with older vehicles that use the k-line?
A: Yes! The HEX-COM+CAN and HEX-USB+CAN are fully backwards compatible with older vehicles that use either single or dual K-lines as well, so they work with all VW/Audi/SEAT/Skoda from 1996-2005.
