Will VAG-COM work with my car?
VAG-COM
will work with most Volkswagen and Audi models sold worldwide from
1994 to 2009+. It will work with some cars as early as 1990. It
will also work with most 1996-2009+ SEAT and Skoda models.
Certain
2003 and newer models (see below) do require the CAN-enabled interfaces
(HEX-USB or Micro-CAN), whereas earlier cars only require the KII-USB
interfaces.
If your
VW or Audi has a 16-pin OBD-II style Data Link Connector, VAG-COM will
definitely work. If your car has the old '2x2' Data Link Connection,
please check the wiring to the connectors: if there are four wires,
VAG-COM should work. If there are only three, it won't.
Please
see these Application
Charts where you can select your model and see which modules
can communicate with VAG-COM. Also see the Ross-Tech Issues
page for a few things that may not work as expected.
What
is CAN and why is that different to the earlier cars?
CAN stands
for Controller Area Network. CAN is a new means of communicating with
the car for diagnostics used by the latest generations of VW, Audi,
SEAT, and Skoda vehicles (certain models from 2003). Unlike the older
ISO9141 system which 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.
Which
VW/Audi/Seat/Skoda cars use CAN for diagnostics?
Some examples
of the newer cars that require the CAN-enabled interface are:
- All Golf-5
platform cars (A5 platform) including:
- 2003+
VW Touran (1T chassis)
- 2004+
VW Golf (1K 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)
- 2005+
Golf Plus (5M chassis)
- 2005+
Seat Leon (1P chassis)
- 2005.5+
Jetta (1K chassis)
- 2006+
Eos (1F 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)
Requires VAG-COM version 500.0 or newer!
- 2005.5+
VW Passat (B6 Platform, 3C chassis)
Will
a HEX-USB interface work with the earlier non-CAN cars?
Yes. The
HEX interfaces support the earlier non-CAN cars as well as the later
CAN-enabled cars.
How
do I access the earlier cars with the 2x2 diagnostic connector or the
VW LT Van with the round Mercedes connector?
You can
purchase the 2x2 extension cable
for just £15 (inc VAT and delivery) or the LT
Van adapter for just £34 (inc VAT and delivery).
What
are the computer requirements?
A PC running
Windows. The minimum recommended spec is:
- at
least a 500 MHz Pentium-3 (or AMD equivalent)
- 64MB of RAM
- Windows 98SE or newer. (Windows XP or newer for best performance)
VAG-COM
may work on some lesser PC's, but anything less than the above recommendation
is unsupported. USB interfaces will not work at all with Windows 95 or NT4.
Available disk-space is a total non-issue, VAG-COM requires less than 25 MB.
Systems running Windows in a virtualized environment (for example Virtual PC on a Mac) are not supported.
