2.8 Vehicle Coverage
The VAG Scanner is speciallydesigned to work with most
Volkswagen and Audis sold worldwide of 1990 or newer models.
If a VW / AUDI has a 16-pin OBD - II style Data Link Con-
nector (DTC), the code reader will certainly work. If it has an old-
style 2x2 Data Link Connector (DTC), then it depends on whether
there are 4 or 3 wires connecting to the pins. If there are 4 wires,
each connecting a pin, then it will work. If there are only 3 wires,
leaving one pin disconnected, then it will not work.
For VW/AUDI with old-style2x2 Data Link Conneetor(DTC),
you need to have a 2x2 cabling adapter which is not included
in this product package.
