  -- Eliminates the most common failure mode.

The car end of this interface is an OBD-II type connector which plugs right in to most 1994 and newer VW's and 1996 and newer Audis.   Most 1990-1995 Audis and 1990-1993 VW's have the "2x2" data link connector, click here for more info.

Extending this Interface:

The cable on this adapter is about 6 feet long -- just right for most laptops.    You may be able to extend this interface another 6 to 10 feet with a USB extension cord, but we don't recommend or support it because the USB standard does not allow extension cords!   If you plan to use a desktop PC, please order a HEX-COM instead. 

Notes:

• This interface requires a special driver to be installed on your PC.  It does not emulate a COM port.   That means this interface will not work with any other software besides VAG-COM.

• We do not sell any interface adapters  as a "Stand-Alone" products.   We only sell them with our VAG-COM software.

Known Issues:

• This interface performs best with Windows-XP.   It can be used with Windows 98, ME, or 2000, but Performance may be significantly degraded by using an OS other than Windows XP. If you are planning to keep using Windows 98, ME, or 2000, we recommend using a Quatech card with one of our Serial Interfaces as per our FAQ.

• The TWIN-USB prefers to be plugged into the car before being plugged into the PC.  On some laptops, the TWIN-USB may not work correctly if you plug it into the PC before you plug it into the car.   If a TWIN-USB won't "Talk" to the car, first go to the Options Screen, click TEST and make sure your the TWIN-USB is identified correctly.     If VAG-COM correctly identifies it, do the following: 
  -  Leave the TWIN-USB plugged into the car.
  -  Unplug it from the PC for 10 seconds
  -  Plug it back into the PC and wait 10 more seconds.
  This will fix almost all "TWIN USB Won't Talk" problems.
