Audi/VW CAN+KKL Interfaces
for Diagnostic
-
If
the PC you're planning to use has a Serial Port, then we
suggest you get a Serial Interface. Serial
interfaces are less expensive and have slightly more precise
protocol timing. They are also completely
compatible with older versions of Windows (Windows 95, 98,
ME, NT4 and 2000). Serial Interfaces can also be used
with Desktop PC's since they are compatible with standard
RS232 extension cords (which we stock in 15', 25' and 50'
lengths).
-
If
you have a newer laptop which doesn't have a Serial Port,
then you must get a USB interface.
Add-on USB<->Serial Converters are not supported!
USB interfaces require Windows 98, ME, 2000 or XP.
They will not work with Windows 95 or NT4!
USB interfaces work best with Windows XP.
CAN stands for
Controller Area Network and is a different diagnostic
hardware/software method from the system used on older
vehicles. All Golf-5 platform cars (including Golf-5, VW
Touran, new VW Caddy, Seat Altea, new Skoda Octavia, new Audi
A3) as well as the 2004+ Audi A8L and new Audi A6.
Audis
that require Dual K-Lines:
-
All B6/8E
chassis A4/S4 models with Xenon headlights.
-
All 2002 and
newer A6 models, including the Allroad.
"Difficult"
older cars
Include those with
1991-1994 Audi TDI engines which run the diagnostic protocols
at 240 (yes, two hundred forty) bits per second,
1993-1994 Audi 2.6L engines with Hella ECU's, as well as any
older car that has the "Check Engine" light
connected to the L-Line (check wiring diagrams -- we don't
have an exact list).
"Lame
Port" laptops
Include many
Compaq Presario Laptops, some Acer models, and some
ultra-portable Dell models which have the serial port on a
separate port expander. All of our current Interfaces
(shown above) work fine with these PC's. Our
older ISO-COM (no longer in production) and many third-party
interfaces based on opto-couplers do not work
with these PC's.
