• Automatic identification of control modules.
• Plain-language fault code descriptions.
• Guided procedures for common tasks.

3.2 What Type of Computer is Required to Run VCDS?

VCDS requires a Windows-based computer with a USB port. Ross-Tech officially supports Windows XP, Vista, 7, 8, and 10. While not officially supported, users have reported success running VCDS on Apple and Linux computers using virtualization software.

3.3 How Often are VCDS Software Updates Released?

Ross-Tech regularly releases software updates to improve functionality, add support for new vehicle models, and address any known issues. Updates are typically released several times a year and are available for free to registered users.

4. Choosing the Right VCDS Interface for Your Needs

Ross-Tech offers different VCDS interfaces to suit various needs and budgets. The two main options are the HEX-V2 and HEX-NET.

4.1 HEX-V2 vs. HEX-NET: Which VCDS Interface is Right for Me?

Here’s a comparison of the HEX-V2 and HEX-NET interfaces to help you choose the right one:

Feature	HEX-V2	HEX-NET
Connection	USB	USB & Wi-Fi
Vehicle Coverage	VAG (VW, Audi, Seat, Skoda, Bentley)	VAG (VW, Audi, Seat, Skoda, Bentley)
VIN Limit	Limited or Unlimited options	Unlimited
Mobile App	No	Yes (VCDS-Mobile)
