2.7 Vehicle Coverage
The MaxScan VAG405 VW/AUDI Code Scanner is specially
designed 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 Connector (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-style 2x2 Data Link Connector (DTC), you
need to have a 2x2 cabling adapter which is not included in this
product package.
