Does anyone know what version/type of vag-com I need for the above car? Looked at ross-tech, but there seem to be loads of diferent types.
All the software versions will work with your car, its just a matter of getting the right cable.
2007 A3 TDI 170 S Line
Sold - 2002 S3
The Ross-Tech KEY or HEX series interfaces will work with this car. The KEY series is intended for enthusiasts and the HEX series is the professional series. Pick the serial or the USB version according to your computer.
The HEX series adds the CAN diagnostic capability. You really do not need this for your car.
