Please Note: Older VCDS versions may not support all of the model years listed. In this particular case you will see that only the HEX+CAN series interface is compatible.
Look horizontally across the VCDS Compatibility Chart until you find the Model Year 2006 and you can determine which interface(s) is required for that Chassis. Note that the Chassis Type “4F” is listed under that model. See the Model information Column for Audi to find the A6 Model. The 7th and 8th digits are 4F for Audi A6 (4F), the 10th digit is 6 which stands for Model Year (MY) 2006.
The Chassis type will usually be found in these digits. To find the Chassis Type for your car, look at the 7th and 8th digits of the VIN number. The following VCDS Compatibility Charts are based on Model and Chassis Type.
